1. BASIS OF PRESENTATION

Basis of Presentation

Southwest Airlines Co. (the "Company" or "Southwest") operates Southwest Airlines, a major passenger airline that provides scheduled air transportation in the United States and near-international markets. The unaudited Condensed Consolidated Financial Statements include accounts of the Company and its wholly owned subsidiaries.

The accompanying unaudited Condensed Consolidated Financial Statements of the Company and its subsidiaries have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles in the United States ("GAAP") for complete financial statements as required in Form 10-K. The unaudited Condensed Consolidated Financial Statements for the interim periods ended June 30, 2026 and 2025 include all adjustments which are, in the opinion of management, necessary for a fair presentation of the results for the interim periods. This includes all normal and recurring adjustments and elimination of significant intercompany transactions. Financial results for the Company and airlines in general can be seasonal in nature. In most markets the Company serves, demand for air travel has historically been greater, and, therefore, revenues in the airline industry tend to be stronger, during the summer months and peak travel periods, including holidays. As a result, in many cases, the Company's results of operations reflect this seasonality. However, air travel is also significantly impacted by general economic conditions, the amount of disposable income available to consumers and changes in consumer behavior, unemployment levels, corporate travel budgets, global pandemics, extreme or severe weather and natural disasters, fears or actual acts of terrorism or war, governmental actions, and other factors beyond the Company's control. These and other factors, such as the price of jet fuel in some periods, have created, and may continue to create, significant volatility in the Company's financial results. Operating results for the three and six months ended June 30, 2026, are not necessarily indicative of the results that may be expected for future quarters or for the year ended December 31, 2026. For further information, refer to the Consolidated Financial Statements and footnotes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2025.

Breakage Revenue

During second quarter 2026, in association with its former policy in which flight credits (funds that may be applied towards future travel) did not expire, the Company determined that a reversal of a portion of previously recognized, prior years' breakage revenue was warranted. Following the Company's prior policy decision in July 2022 to eliminate the expiration date on flight credits issued, approximately $7.9 billion in non-expiring flight credits were issued by the Company between July 2022 and December 2025, and the Company had previously estimated, based on both historical and projected redemption behavior at that time, approximately 23 percent of those non-expiring flight credits would not be redeemed by Customers, and correspondingly recorded estimated breakage revenue for those amounts over the time period July 2022 through December 2025. Based on the most recent flight credit redemption trends and updated projections of future redemptions for the remaining available non-expiring flight credits, the Company now believes that approximately 20 percent of the non-expiring flight credits originally issued between July 2022 and December 2025 will not be redeemed by Customers. Approximately $1.8 billion of such flight credits remain available as of June 30, 2026. As a result of this change in estimate, the Company is recording a second quarter 2026 reversal of breakage revenue of $285 million. No breakage revenue related to this population of non-expiring flight credits was recognized in first half 2026; thus, the entire amount of the second quarter 2026 breakage revenue reversal relates to years 2022 through 2025.

The timing of this adjustment in the second quarter 2026 was impacted by a combination of quantitative trends and qualitative factors affecting Customer behavior, including the Company's recent significant business transformation initiatives, changes to fare products and distribution channels, and changes to its flight credit policies. These factors altered historical Customer redemption patterns and reduced the predictive value of historical information observed during the period in which the credits were issued. As a result, management determined that Customer behavior

[Notes to Condensed Consolidated Financial Statements](#ibb50983d4ceb408f939747d9c4b61ba4_28) Southwest Airlines Co.  Notes to Condensed Consolidated Financial Statements  (unaudited)

observed through the second quarter of 2026 provided a more reliable basis for estimating the ultimate level of unredeemed flight credits than had previously been determined.

The Company implemented a change to its flight credit policy, in which flight credits created from reservations booked and ticketed or voluntarily changed on or after May 28, 2025, will typically have a specified expiration date of one year or less, depending on the type of fare purchased and form of payment used. However, some non-expiring flight credits continued to be issued subsequent to May 28, 2025, primarily due to reservations for future travel that were already in place as of that date that were subsequently modified or cancelled. This second quarter 2026 breakage revenue adjustment, and its corresponding increase to Air Traffic Liability, resulted in the following impact to results:

| (in millions, except per share amounts) | Three months ended June 30, 2026 |
| --- | --- |
| Breakage revenue adjustment | $(285) |
| Net income* | (185) |
| Net income per basic share | (0.38) |
| Net income per diluted share | (0.37) |

 * net of profit-sharing benefit and income taxes

Breakage estimates are based on Customers' historical travel behavior as well as assumptions about their future travel behavior. Assumptions about the Customers' future travel behavior can be impacted by several factors including but not limited to: fare increases; fare sales; changes to the Company's ticketing policies; changes to the Company’s refund, exchange, and unused flight credit policies; seat availability; economic factors; and the Company's observations about changes in actual Customer use of flight credits. See Note 5 for further information.

Operating Segments and Related Disclosures

The Company's chief operating decision maker, the Company's President, Chief Executive Officer, & Vice Chairman of the Board of Directors, assesses performance for the Company's single reportable segment and decides how to allocate resources based on its Net income or loss (see the unaudited Condensed Consolidated Statement of Comprehensive Income).

For single reportable segment-level financial information, total assets, revenues from external Customers, depreciation and amortization expense, interest income and interest expense, provision for income taxes, other non-operating expenses, and significant non-cash transactions, see Item 1. Financial Statements.

2. NEW ACCOUNTING PRONOUNCEMENTS

On May 19, 2026, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2026‑02, Environmental Credits and Environmental Credit Obligations (Topic 818), which establishes a new accounting model for environmental credits and related obligations. ASU 2026-02 provides guidance on the recognition, measurement, presentation, and disclosure of environmental credits, as well as obligations that may be settled using such credits. Under ASU 2026-02, environmental credits are recognized as assets when it is probable they will be used to satisfy a compliance obligation, transferred, or otherwise utilized in a qualifying manner. The accounting for these credits, including subsequent measurement, depends on whether they are expected to be used for compliance or noncompliance purposes. ASU 2026-02 also requires entities to recognize environmental credit obligations as activities occur that give rise to a regulatory requirement and introduces a measurement approach that is generally linked to the cost basis of credits expected to be used to settle such obligations. This standard is effective for public business entities for annual reporting periods beginning after December 15, 2027, including

[Notes to Condensed Consolidated Financial Statements](#ibb50983d4ceb408f939747d9c4b61ba4_28) Southwest Airlines Co.  Notes to Condensed Consolidated Financial Statements  (unaudited)

interim periods within those annual periods, with early adoption permitted. The Company is evaluating this new standard, but does not expect it to have a significant impact on its financial statement presentation or results.

On September 18, 2025, the FASB issued ASU 2025-06, Accounting for and Disclosure of Software Costs. The new standard modernizes the guidance to reflect the software development approaches currently being used by removing all references to "development stages" from Accounting Standards Codification ("ASC") 350-40 Intangibles—Goodwill and Other - Internal-Use Software. Under ASU 2025-06, only the following criteria in ASC 350-40-25-12(b) and (c) must be met for entities to begin capitalizing software costs: (i) management, with the relevant authority, implicitly or explicitly authorizes and commits to funding a computer software project and (ii) it is probable that the project will be completed and the software will be used to perform the function intended (referred to as the "probable-to-complete recognition threshold"). This standard is effective for all entities for annual reporting periods beginning after December 15, 2027, and interim reporting periods within those annual reporting periods, with early adoption permitted. Entities may apply the guidance prospectively, retrospectively, or via a modified prospective transition method. The Company is evaluating this new standard, but does not expect it to have a significant impact on its financial statement presentation or results.

On July 30, 2025, the FASB issued ASU 2025-05, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets. This standard includes the option for entities to elect a practical expedient that assumes current conditions as of the balance sheet date do not change for the remaining life of the asset as a part of estimating expected credit losses. The Company has elected this practical expedient as of first quarter 2026, and there was no significant impact on its financial statement presentation or disclosures.

On November 4, 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. This standard responds to investor input by requiring public companies to disclose, in interim and annual reporting periods, additional information about certain expenses in the notes to the financial statements. This standard does not change the presentation of expense information or expense captions reported on the face of the income statement. This standard is effective for all entities that are subject to Subtopic 220-40, for annual periods beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027, but early adoption is permitted. The Company is evaluating this new standard, but does not expect it to have a significant impact on its financial statement presentation or results.

3. FINANCIAL DERIVATIVE INSTRUMENTS

Fuel Contracts

Airline operators are inherently dependent upon energy to operate and, therefore, are impacted by changes in jet fuel prices. Furthermore, jet fuel typically represents one of the largest operating expenses for airlines. The Company has historically aimed to reduce volatility in operating expenses through its fuel hedging program. However, based on higher fuel hedging premium costs over time and other factors, the Company discontinued its fuel hedging program and terminated its remaining portfolio of fuel hedging contracts, which were scheduled to settle through 2027, to effectively close its fuel hedging portfolio during 2025. The Company does not intend to add additional fuel derivatives.

The Company recorded expenses associated with fuel derivative contracts that settled during the three and six months ended June 30, 2025 and for amounts that remain in Accumulated Other Comprehensive Income ("AOCI") associated with previously terminated hedges during the three and six months ended June 30, 2026 and 2025. These expenses are reflected as a component of Aircraft fuel and related taxes expense within the unaudited Condensed Consolidated Statement of Comprehensive Income:

| --- | --- | --- | --- | --- |
| Fuel derivative contracts | — | $40 | — | $69 |

As of June 30, 2026, approximately $79 million remained in AOCI related to these previously closed positions, with approximately $58 million to be recognized in the remainder of 2026 and $21 million to be recognized in 2027. This balance in AOCI, which does not include any tax impact, will also be characterized as premium expense and similarly reclassified as an increase to Aircraft fuel and related taxes expense in future periods when the originally forecasted transactions occur (through the end of 2027) and is net of the impact of the cash proceeds from the hedge terminations. See Note 4 for additional information on AOCI.

All cash flows associated with purchasing and selling fuel derivatives (including terminations) are classified as Other operating cash flows in the unaudited Condensed Consolidated Statement of Cash Flows.

Interest Rate Derivatives

The Company holds interest rate swap agreements, which collectively qualify as a fair value hedge, related to its $750 million 5.25% unsecured notes due 2035. The primary objective for the Company's use of these agreements is to hedge against changes in the fair value of the debt instrument caused by changes in market interest rates, specifically SOFR, by converting the fixed rate interest of the debt to a floating rate. Under these agreements, the Company pays SOFR plus a margin on the notional amount of the debt and receives payments based on the fixed stated rate of the notes.

The fair values of the interest rate swap agreements, which are adjusted regularly, have been aggregated by counterparty for classification in the unaudited Condensed Consolidated Balance Sheet. The following table presents the location of the Company’s interest rate derivative instruments within the unaudited Condensed Consolidated Balance Sheet:

| Derivatives designated as hedges | Derivatives designated as hedges / Balance Sheet | Liability derivatives / Fair value at | Liability derivatives / Fair value at |
| --- | --- | --- | --- |
| (in millions) | location | 6/30/2026 | 12/31/2025 |
| Interest rate derivative contracts | Other noncurrent liabilities | 28 | 16 |

The corresponding offsetting adjustment related to the liability (or asset) associated with the Company’s fair value hedges is to Long-term debt less current maturities.

4. COMPREHENSIVE INCOME

Comprehensive income (loss) includes changes in the fair value of certain financial derivative instruments that qualified for hedge accounting and actuarial gains/losses arising from the Company’s postretirement benefit obligation. The Company terminated its remaining portfolio of fuel hedging contracts during second quarter 2025, which were scheduled to settle through 2027, to effectively close its fuel hedging portfolio and program. See Note 3. The differences between Net income and Comprehensive income for the three and six months ended June 30, 2026 and 2025 were as follows:

| (in millions) | Three months ended June 30, 2026 | Three months ended June 30, 2025 |

5. REVENUE

Passenger Revenues

The Company’s contracts with its Customers primarily consist of ticket sales, which are initially deferred as Air traffic liability. Passenger revenue associated with tickets is recognized when the performance obligation to the Customer is satisfied, which is primarily when travel is provided. For air travel on Southwest, the amount of tickets (which includes flight credits—also referred to as partial tickets) that will go unused, referred to as breakage, is estimated and recognized in Passenger revenue once the scheduled flight date has passed, in proportion to the pattern of rights exercised by the Customer.

Revenue is categorized by revenue source as the Company believes this best depicts the nature, amount, timing, and uncertainty of revenue and cash flow. The following tables provide the components of Passenger revenue and Other revenue recognized for the three and six months ended June 30, 2026 and 2025:

[Notes to Condensed Consolidated Financial Statements](#ibb50983d4ceb408f939747d9c4b61ba4_28) Southwest Airlines Co.  Notes to Condensed Consolidated Financial Statements  (unaudited)

| (in millions) | Three months ended June 30, 2026 | Three months ended June 30, 2025 | Six months ended June 30, 2026 | Six months ended June 30, 2025 |
| --- | --- | --- | --- | --- |
| Passenger non-loyalty | $6,104 | $5,448 | $11,292 | $10,214 |
| Passenger loyalty - air transportation | 766 | 870 | 1,454 | 1,670 |
| Passenger ancillary sold separately (b) | 875 | 309 | 1,591 | 554 |
| Total passenger revenues | $7,745 | $6,627 | $14,337 | $12,438 |

(a) Includes a reversal of previously recognized breakage revenue of approximately $285 million, related to the periods July 2022 through December 2025. See Note 1 for further information.

(b) The increase in Passenger ancillary sold separately in the three and six months ended June 30, 2026 as compared with the respective prior periods was due to the Company's initiative to implement new ancillary products—bag fees for most fare products beginning May 28, 2025, and operating assigned and extra legroom seating for travel beginning January 27, 2026, which includes the co-brand impact associated with those initiatives.

| (in millions) | Three months ended June 30, 2026 | Three months ended June 30, 2025 | Six months ended June 30, 2026 | Six months ended June 30, 2025 |
| --- | --- | --- | --- | --- |
| Loyalty program | $578 | $536 | $1,135 | $1,081 |
| Other | 59 | 37 | 117 | 67 |
| Total other revenues | $637 | $573 | $1,252 | $1,148 |

Through the Company's co-branded credit card agreement ("Co-brand Agreement") with JPMorgan Chase Bank, N.A. ("Chase"), the Company sells loyalty points, certain marketing benefits, which consist of the use of the Southwest Airlines brand and access to Rapid Rewards Member lists, licensing and advertising elements, the use of the Company’s resource team, and other airline benefits. The Company allocates consideration received to performance obligations based on the relative standalone selling price of those obligations.

In 2025, the Company and Chase amended the Co-brand Agreement—in the first quarter to extend the term of the agreement and add enhanced airline benefits for Cardmembers associated with the Company's planned assigned and extra legroom seating initiative, which went into effect on January 27, 2026, and again in the second quarter to add benefits to Cardmembers related to the Company's changes in its checked bag policy that went into effect on May 28, 2025. For each change to the agreement, the Company estimated the selling prices and volumes over the term of the amended agreement in order to determine the allocation of proceeds to each of the three performance obligations identified in the agreement, which have been characterized as a transportation component, a marketing component, and an airline benefits component. The allocations utilized are reviewed to determine if adjustment is necessary any time there is a modification to the Co-brand Agreement.

The Company defers revenue for points earned by Customers through the Co-brand Agreement and subsequently records Passenger revenue related to loyalty point redemptions for air travel when the travel is delivered. The marketing elements are recognized as Other revenue and the airline benefits are recognized as Passenger revenue when the performance obligations related to those services are satisfied, which is generally the same period consideration is received from Chase. As a result of the 2025 amendments to the Co-brand Agreement, a larger portion of the Company's co-brand Chase® Visa credit card benefits from Chase are now being classified within Passenger revenues commensurate with the Company's ability to satisfy the associated performance obligations, which began in mid-2025 associated with its change in policy for checked bags, and in first quarter 2026 associated with its implementation of assigned and extra legroom seating initiatives.

As of June 30, 2026, and December 31, 2025, the components of Air traffic liability, including contract liabilities based on tickets sold and unused flight credits available to the Customer, both of which are net of recorded breakage, and loyalty points available for redemption, within the unaudited Condensed Consolidated Balance Sheet were as follows:

[Notes to Condensed Consolidated Financial Statements](#ibb50983d4ceb408f939747d9c4b61ba4_28) Southwest Airlines Co.  Notes to Condensed Consolidated Financial Statements  (unaudited)

| (in millions) | Balance as of / June 30, 2026 | Balance as of / December 31, 2025 |
| --- | --- | --- |
| Air traffic liability - passenger travel and ancillary passenger services | $4,010 | $2,830 |
| Air traffic liability - loyalty program | 4,174 | 4,334 |
| Total Air traffic liability | $8,184 | $7,164 |

The balance in Air traffic liability - passenger travel and ancillary passenger services also includes flight credits not currently associated with a ticket that can be applied by Customers towards the purchase of future travel. These flight credits are typically created as a result of a prior ticket cancellation or exchange, and are recorded net of associated breakage. Rollforwards of the Company's Air traffic liability - loyalty program for the three and six months ended June 30, 2026 and 2025 were as follows:

| (in millions) | Three months ended June 30, 2026 | Three months ended June 30, 2025 | Six months ended June 30, 2026 | Six months ended June 30, 2025 |
| --- | --- | --- | --- | --- |
| Air traffic liability - loyalty program - beginning balance | $4,278 | $4,841 | $4,334 | $4,849 |
| Amounts deferred associated with points awarded | 695 | 748 | 1,357 | 1,565 |
| Revenue recognized from points redeemed - Passenger | (766) | (870) | (1,454) | (1,670) |
| Revenue recognized from points redeemed - Other | (33) | (26) | (63) | (51) |
| Air traffic liability - loyalty program - ending balance | $4,174 | $4,693 | $4,174 | $4,693 |

Air traffic liability includes consideration received for ticket and loyalty related performance obligations which have not been satisfied. Rollforwards of the amounts included in Air traffic liability as of June 30, 2026 and 2025 were as follows:

| (in millions) | Six months ended June 30, 2026 | Six months ended June 30, 2025 |
| --- | --- | --- |
| Air traffic liability - beginning balance | $7,164 | $8,242 |
| Current period sales (a) | 14,891 | 12,489 |
| Revenue from amounts included in contract liability opening balances | (3,515) | (3,855) |
| Revenue from current period sales | (10,356) | (8,580) |
| Air traffic liability - ending balance | $8,184 | $8,296 |

(a)Current period sales include passenger travel, ancillary services, flight loyalty, and partner loyalty

On May 28, 2025, the Company implemented a change to its flight credit policy. Flight credits created from reservations booked and ticketed or voluntarily changed on or after May 28, 2025, will typically have a specified expiration date of one year or less, depending on the type of fare purchased and form of payment used. Flight credits issued between July 28, 2022, and May 28, 2025, including any future issuances associated with bookings made prior to the policy change on May 28, 2025, do not have an expiration date.

However, some non-expiring flight credits continued to be issued subsequent to May 28, 2025, primarily due to reservations for future travel that were already in place as of that date that were subsequently modified or cancelled. During second quarter 2026, in association with its former policy in which flight credits did not expire, the Company determined that a reversal of a portion of previously recognized breakage revenue was warranted. Approximately $7.9 billion in non-expiring flight credits were issued by the Company between July 2022 and December 2025. The Company had estimated a portion of those non-expiring flight credits would not be redeemed by Customers, and correspondingly recorded estimated breakage for those amounts over those periods. Due to higher-than-projected Customer redemptions of these non-expiring flight credits, along with updated projections of future redemptions, the Company has revised its estimates with regard to the remaining non-expiring flight credits that remain available for redemption. The Company determined that a reversal of a portion of previously recognized

[Notes to Condensed Consolidated Financial Statements](#ibb50983d4ceb408f939747d9c4b61ba4_28) Southwest Airlines Co.  Notes to Condensed Consolidated Financial Statements  (unaudited)

breakage revenue of $285 million was warranted and recorded this adjustment during the three months ended June 30, 2026. This change in breakage revenue, and the corresponding impact to Passenger revenue, is considered a change in estimate (see Note 1 for further clarification).

The Company issues vacation travel credits for cancelled bookings resulting from the Getaways by Southwest™ ("Getaways") product, and these credits have an 18-month expiration period from the original booking date. As the Company believes that a portion of Customer travel credits (both flight credits and Getaways travel credits) issued will not be redeemed, it estimates and records breakage associated with such amounts.

The amount of Customer travel credits represents approximately 6 percent and 5 percent of the total Air traffic liability balance as of June 30, 2026, and December 31, 2025, respectively.    

6. NET INCOME PER SHARE

The following table sets forth the computation of basic and diluted net income per share (in millions, except per share amounts). Basic net income per share is calculated by dividing Net income by the weighted average of shares outstanding during the period. Diluted net income per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock. For the three and six months ended June 30, 2025, an immaterial number of shares related to the Company's restricted stock units were excluded from the denominator because inclusion of such shares would be antidilutive. There were no antidilutive restricted stock units for the three and six months ended June 30, 2026. During second quarter 2025, the Company's remaining balance of 1.25 percent Convertible Senior Notes due 2025 (the "Convertible Notes") of $1.6 billion was repaid, settling both principal and accrued interest. For the three and six months ended June 30, 2025, the weighted-average impact for the outstanding portion of the Convertible Notes was immaterial.

| Line item | Three months ended June 30, 2026 | Three months ended June 30, 2025 | Six months ended June 30, 2026 | Six months ended June 30, 2025 |
| --- | --- | --- | --- | --- |
| NUMERATOR: |  |  |  |  |

| Basic | $0.48 | $0.40 | $0.93 | $0.11 |
| Diluted | $0.47 | $0.39 | $0.92 | $0.11 |

7. FAIR VALUE MEASUREMENTS

Accounting standards pertaining to fair value measurements establish a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions.

[Notes to Condensed Consolidated Financial Statements](#ibb50983d4ceb408f939747d9c4b61ba4_28) Southwest Airlines Co.  Notes to Condensed Consolidated Financial Statements  (unaudited)

As of June 30, 2026, the Company held certain items that are required to be measured at fair value on a recurring basis, including cash equivalents. The Company may also from time to time hold short-term investments and available-for-sale securities. The majority of the Company’s cash equivalents consist of instruments classified as Level 1. However, the Company classifies any certificates of deposit and time deposits it holds as Level 2 due to the fact that the fair value for these instruments is determined utilizing observable inputs in non-active markets. Equity securities primarily consist of investments with readily determinable market values associated with the Company’s excess benefit plan.

The Company’s interest rate derivative instruments consist of over-the-counter contracts, which are not traded on a public exchange. Interest rate derivatives currently consist solely of swap agreements. See Note 3 for further information on the Company’s derivative instruments and hedging activities. The fair values of swap contracts are determined based on inputs that are readily available in public markets or can be derived from information available in publicly quoted markets. Therefore, the Company has categorized these swap contracts as Level 2. The Company also considered counterparty credit risk and its own credit risk in its determination of all estimated fair values. The Company consistently applied these valuation techniques in all periods presented and believes it obtained the most accurate information available for the types of derivative contracts it holds.

Included in Equity securities are the Company’s investments primarily associated with its deferred compensation plans, which consist of mutual funds that are publicly traded and for which market prices are readily available. These plans are non-qualified deferred compensation plans designed to hold contributions in excess of limits established by the Internal Revenue Code of 1986, as amended. The distribution timing and payment amounts under these plans are made based on the participant’s distribution election and plan balance. Assets related to the funded portions of the deferred compensation plans are held in a rabbi trust, and the Company remains liable to these participants for the unfunded portion of the plans. The Company records changes in the fair value of plan obligations and plan assets, which net to zero, within the Salaries, wages, and benefits line and Other (gains) losses, net line, respectively, of the unaudited Condensed Consolidated Statement of Comprehensive Income.

The following tables present the Company’s assets and liabilities that are measured at fair value on a recurring basis as of June 30, 2026, and December 31, 2025:

The Company did not have any material assets or liabilities measured at fair value on a nonrecurring basis, or on a recurring basis using significant unobservable inputs (Level 3) during the six months ended June 30, 2026, or the year ended December 31, 2025.

The carrying amounts and estimated fair values of the Company’s short-term and long-term debt (including current maturities), as well as the applicable fair value hierarchy tier, as of June 30, 2026, are presented in the table below. The fair values of the Company’s publicly held debt are determined based on inputs that are readily available in public markets or can be derived from information available in publicly quoted markets; therefore, the Company has categorized these agreements as Level 2. All privately held debt agreements are categorized as Level 3. The Company has determined the estimated fair value of this debt to be Level 3, as certain inputs used to determine the fair value of these agreements are unobservable. The Company utilizes indicative pricing from counterparties and a discounted cash flow method to estimate the fair value of the Level 3 items.

9. COMMITMENTS AND CONTINGENCIES

Commitments

The Company's contractual order book with The Boeing Company ("Boeing") for 737-7 ("-7") and 737-8 ("-8") aircraft (together, the "MAX aircraft"), which extends to 2031, was designed to support the Company's growth and fleet modernization plans, while also providing significant flexibility and optionality to manage its fleet gauge and size, including opportunities to accelerate fleet modernization efforts. The Company received 13 -8 aircraft deliveries from Boeing in second quarter 2026 and retired 10 aircraft (including five 737-700 ("-700") aircraft and the sale of one -700 aircraft and four 737-800 ("-800") aircraft). In addition, during second quarter 2026, the Company exercised six -7 options for delivery in 2027. During the six months ended June 30, 2026, the Company converted 19 2026 deliveries from -7 to -8 firm orders.

Boeing continues to experience delays in fulfilling its commitments with regards to delivery of MAX aircraft to the Company, primarily as a result of manufacturing challenges and delays in achieving Federal Aviation Administration ("FAA") certification of one of its new aircraft types, the -7, for which Southwest expects to be the launch customer. As a result of Boeing's delivery delays, the Company has previously replanned its capacity and delivery expectations multiple times and will continue to closely monitor the ongoing aircraft delivery delays with Boeing and further adjust expectations as needed.

As of June 30, 2026, the Company had the following firm orders and options for future periods:

|  | The Boeing Company | The Boeing Company |  |  |
| --- | --- | --- | --- | --- |
|  | -7 Firm Orders | -8 Firm Orders | -7 or -8 Options | Total |
| 2026 | 82 | 85 | — | 167 |
| 2027 | 37 | 46 | 7 | 90 |
| 2028 | 15 | 50 | 25 | 90 |
| 2029 | 38 | 34 | 18 | 90 |
| 2030 | 45 | — | 45 | 90 |
| 2031 | 45 | — | 45 | 90 |
|  | 262 | 215 | 140 | 617 |

(a) The delivery timing for the -7 is dependent on the FAA issuing required certifications and approvals to Boeing and the Company. The FAA will ultimately determine the timing of the -7 certification and entry into service, and the Company therefore offers no assurances that current estimations and timelines are correct.

[Notes to Condensed Consolidated Financial Statements](#ibb50983d4ceb408f939747d9c4b61ba4_28) Southwest Airlines Co.  Notes to Condensed Consolidated Financial Statements  (unaudited)

(b) The Company has flexibility to designate firm orders or options as -7s or -8s, upon written advance notification as stated in the contract.

(c) Includes 23 -8 deliveries received year-to-date through June 30, 2026. In addition, the Company has included 81 of its 2024 and 2025 contractual but undelivered aircraft (27 -7s and 54 -8s) within its 2026 contractual commitments. The 2026 contractual detail is as follows:

|  | The Boeing Company | The Boeing Company |  |
| --- | --- | --- | --- |
|  | -7 Firm Orders | -8 Firm Orders | Total |
| 2024 Contractual Deliveries | 27 | — | 27 |
| 2025 Contractual Deliveries | — | 54 | 54 |
| 2026 Contractual Deliveries | 55 | 31 | 86 |
| 2026 Combined Contractual Total | 82 | 85 | 167 |

Based on the Company's current agreement with Boeing, capital commitments associated with firm orders as of June 30, 2026, were:

| (in billions) |  | 2027 | 2028 | 2029 | 2030 | 2031 | Total |
| --- | --- | --- | --- | --- | --- | --- | --- |
| Payments for capital commitments | (a) | $3.0 | $2.7 | $2.5 | $1.5 | $1.2 | $14.8 |

(a) Capital commitments associated with the Company's firm orders in 2026 of $3.9 billion include approximately $2.7 billion primarily related to the existing remaining scheduled 86 MAX aircraft to be delivered in 2026 and $1.2 billion related to 58 MAX aircraft (27 -7s and 31 -8s) that were contractually committed for 2024 and 2025, but were not received.

Subsequent to June 30, 2026, and through July 23, 2026, the Company exercised two -7 options for delivery in 2027, resulting in an immaterial change to the Company's capital commitments noted above.

#### Contingencies

The Company is from time to time subject to various legal proceedings and claims arising in the ordinary course of business and records a liability for such claims when it is probable that a loss will be incurred and the amount is reasonably estimable.

On December 27, 2019, a former Customer Service Agent at Oakland International Airport, filed a putative class action complaint in the Superior Court of California, for the County of Santa Clara, against the Company alleging the following seven claims under the California Labor Code and Business & Professions Code: (1) failure to provide meal periods; (2) failure to provide rest periods; (3) failure to pay hourly wages; (4) failure to provide accurate wage statements; (5) failure to timely pay all final wages; (6) unfair competition; and (7) civil penalties for the foregoing. Plaintiff filed a First Amended Complaint on October 15, 2021, that asserted the same causes of action and added a named plaintiff. The First Amended Complaint primarily seeks unpaid wages, interest thereon, and associated civil and statutory penalties, along with attorneys’ fees and costs. On February 26, 2025, the Court granted class certification as to the first cause of action for failure to provide meal periods, denied certification on the second through fourth causes of action, and granted certification on the fifth and sixth causes of action only insofar as they are predicated on the first cause of action. The certified class consists of all of the Company’s non-exempt ground Employees in California who worked a shift in excess of five hours for the time period between October 24, 2014, forward. On April 17, 2025, the Company filed a summary judgment motion arguing that Plaintiffs’ first cause of action, and all causes of action predicated thereon, failed as a matter of law. The motion was granted on July 25, 2025. Judgment was entered in favor of the Company on September 2, 2025, and Plaintiffs filed a notice of appeal on September 4, 2025. On May 6, 2026, Plaintiffs filed their opening appellate brief. The Company’s answering brief is due on August 4, 2026. The Company is currently not able to estimate a range of possible loss with regards to the litigation to which it is a defendant.

10. DEBT

Convertible Notes

On May 1, 2020, the Company completed the public offering of $2.3 billion aggregate principal amount of Convertible Notes, bearing interest at a rate of 1.25 percent, payable semi-annually in arrears. The Company repurchased $689 million during the two year period ending December 31, 2022, and the remaining $1.6 billion principal amount of the Convertible Notes was repaid at maturity during second quarter 2025 utilizing available cash on hand. An immaterial amount of Convertible Note conversions settled at maturity.

Payroll Support Program Loan due 2031

During 2020 and 2021, the Company entered into definitive documentation with the United States Department of the Treasury ("Treasury") with respect to payroll funding support ("Payroll Support") pursuant to three separate Payroll Support programs: the "PSP1 Payroll Support Program" in April 2020 under the Coronavirus Aid, Relief, and Economic Security Act; the "PSP2 Payroll Support Program” in January 2021 under the Consolidated Appropriations Act, 2021; and the "PSP3 Payroll Support Program" in April 2021 under the American Rescue Plan Act of 2021.

As consideration for its receipt of funding under each of these Payroll Support programs, the Company issued promissory notes in favor of Treasury (each initially classified as a component of Long-term debt less current maturities in the unaudited Condensed Consolidated Balance Sheet). The note associated with the PSP1 Payroll Support Program was originally due in April 2030 but was redeemed early on April 17, 2025, in the amount of $976 million. The note associated with the PSP2 Payroll Support Program was originally due in January 2031 but was redeemed early on December 29, 2025, in the amount of $566 million. All payments were made utilizing available cash on hand.

The note associated with the PSP3 Payroll Support Program was originally due in April 2031. On December 30, 2025, the Company made a partial prepayment on this note in the amount of $100 million. On April 22, 2026, the Company made an early prepayment of the outstanding loan balance of $426 million, utilizing available cash on hand.

Term Loan Credit Agreement

On March 11, 2026, the Company entered into a new term loan credit agreement (the "Term Loan Credit Agreement") with a third-party bank, providing for a $500 million senior secured term loan credit facility (the "Term Loan Facility") that was drawn in full on the closing date. The Term Loan Facility matures in full on March 11, 2029, and the Company has the right at any time to prepay the loans, in whole or in part, without premium or penalty, upon at least three business days’ prior written notice to the administrative agent. Amounts prepaid under the Term Loan Credit Agreement may not be reborrowed.

Additionally, the Term Loan Facility includes an uncommitted incremental term loan feature allowing up to $1 billion in incremental term loan commitments to be established from time to time in accordance with the terms and conditions set forth in the Term Loan Credit Agreement. On May 19, 2026, the Company executed an upsize of the Term Loan Facility for $1 billion of incremental term loan commitments, and amended the incremental term loan feature to allow for an additional $1 billion more of available uncommitted funds. As of June 30, 2026, the Company had a total outstanding loan balance of $1.5 billion related to the Term Loan Credit Agreement. The Term Loan Facility is secured by a grant of a security interest in certain aircraft and related assets.

Generally, amounts outstanding under the Term Loan Facility bear interest at interest rates based on either the Term SOFR (as defined in the Term Loan Credit Agreement) for designated interest periods selected by the Company or the Alternate Base Rate (as defined in the Term Loan Credit Agreement), plus an applicable margin. The underlying

[Notes to Condensed Consolidated Financial Statements](#ibb50983d4ceb408f939747d9c4b61ba4_28) Southwest Airlines Co.  Notes to Condensed Consolidated Financial Statements  (unaudited)

Term SOFR is subject to a floor of 0.00% per annum, and the Alternate Base Rate is subject to a floor of 1.00% per annum.

Revolving Credit Facility

As of June 30, 2026, the Company had access to $1.5 billion under its amended and restated revolving credit facility (the "Amended Credit Agreement"), which expires in August 2028, reflecting the Company’s exercise of the accordion feature to increase the size of the facility on July 22, 2025. For the six months ended June 30, 2026 and 2025, there were no amounts outstanding under the Amended Credit Agreement.

(a)A revenue passenger mile is one paying passenger flown one mile. Also referred to as "traffic," which is a measure of demand for a given period.

(b)An available seat mile is one seat (empty or full) flown one mile. Also referred to as "capacity," which is a measure of supply or the space available to carry passengers in a given period.

(c)Revenue passenger miles divided by available seat miles.

(d)Seats flown is calculated using total number of seats available by aircraft type multiplied by the total trips flown by the same aircraft type during a particular period.

(e)Seats per trip is calculated by dividing seats flown by trips flown.

(f)Calculated as passenger revenue divided by revenue passenger miles. Also referred to as "yield," this is the average cost paid by a paying passenger to fly one mile, which is a measure of revenue production and fares.

(g)Calculated as operating revenues divided by available seat miles. Also referred to as "operating unit revenues" or "RASM," this is a measure of operating revenue production based on the total available seat miles flown during a particular period.

(h)Calculated as passenger revenue divided by available seat miles. Also referred to as "passenger unit revenues", this is a measure of passenger revenue production based on the total available seat miles flown during a particular period.

(i)Calculated as operating expenses divided by available seat miles. Also referred to as "unit costs" or "cost per available seat mile" or "CASM," this is the average cost to fly an aircraft seat (empty or full) one mile, which is a measure of cost efficiency.

Financial Highlights

The Company reports its results in accordance with GAAP. The Company also provides certain non-GAAP financial measures which the Company's management also utilizes to evaluate its ongoing financial performance, and the Company believes provides additional insight to investors as supplemental information to its GAAP results, as noted in the following tables. See Note Regarding Use of Non-GAAP Financial Measures and the Reconciliation of Reported Amounts to Non-GAAP Financial Measures for additional detail regarding non-GAAP financial measures.

Despite a dynamic cost and fuel environment, the Company’s Operating income, Net income, and Net income per share, diluted, for the three and six months ended June 30, 2026, on a GAAP and non-GAAP basis, improved compared with the same prior year period, driven primarily by strong revenue performance, including an all-time quarterly record Operating revenue performance for the three months ended June 30, 2026, partially offset by higher Aircraft fuel and related taxes expense and Salaries, wages, and benefits expense. On a GAAP basis, the Company’s results for the three and six months ended June 30, 2026, included a reversal of $285 million of breakage revenue recorded in prior years related to a portion of flight credits issued to Customers between July 2022 and December 2025 that have either been redeemed or are expected to be redeemed in future periods. This adjustment was treated as a special item and excluded from the Company’s presentation of non-GAAP results. See Note Regarding Use of Non-GAAP Financial Measures and Notes 1 and 5 to the unaudited Condensed Consolidated Financial Statements for further information. Operating expense for the six months ended June 30, 2025, on a non-GAAP basis, excluded pre-tax charges of $115 million, most notably $62 million related to severance and related professional fees associated with the Company's February 2025 reduction in workforce.

Company Overview

The Company has substantially completed the implementation of its previously announced transformational initiatives, which were planned and designed to attract new Customers and improve both the Company's operational and financial performance. Since the introduction of assigned and extra legroom seating on January 27, 2026, the Company has successfully integrated these offerings into its operations, contributing to improved passenger yields and incremental revenue. Despite significantly higher fuel costs, results reflect record revenue performance, significant earnings growth and margin expansion, broad demand strength, continued cost discipline, and strong Customer engagement with the Company’s enhanced product offering.

The Company has also continued to enhance its onboard offerings, with improvements such as in-seat power, larger overhead bins, and upgraded WiFi, with the first Starlink-equipped aircraft entering service on June 22, 2026, marking the beginning of a new era of inflight connectivity at Southwest. Work is well underway on a refreshed cabin design, including new, more comfortable RECARO seats. As of July 22, 2026, 107 aircraft retrofitted with RECARO seats have been placed into service. In addition, the Company entered into new partnerships with Singapore Airlines, which will enable jointly operated itineraries connecting through the carriers' shared gateway airports in Los Angeles, Seattle-Tacoma, and San Francisco, and with Air Premia, which will enable travel across the Pacific with interline connections at the carriers' shared gateway airports in Honolulu, Los Angeles, and San Francisco. Since February 13, 2025, the Company has implemented and/or announced strategic partnerships with a total of nine carriers, through which Customers can book itineraries that connect the Company's vast domestic network to destinations around the world.

The ongoing geopolitical developments in the Middle East continue to impact the market prices of products that are derived from crude oil, including jet fuel. The Company’s second quarter Aircraft fuel and related taxes expense was $2.2 billion, or $3.92 per gallon, compared with the first quarter Aircraft fuel and related taxes expense of $1.4 billion, or $2.73 per gallon. The forward curve on July 17, 2026 implied a third quarter 2026 fuel cost per gallon, including related taxes, between $3.70 and $3.75. The Company currently expects to utilize approximately 532 million gallons of jet fuel during third quarter 2026.

In second quarter 2026, the Company also paid $88 million to Shareholders through dividends. See "Liquidity and Capital Resources" below for further information.

To further improve its financial performance, the Company has also intensified its network optimization efforts. Effective June 4, 2026, the Company suspended operations at Chicago O'Hare International Airport and Washington Dulles International Airport and reduced staffing at Hartsfield-Jackson Atlanta International Airport, Fort Lauderdale-Hollywood International Airport, and Philadelphia International Airport. A majority of affected Employees were able to transfer to similar positions across the Company's network and remain employed by Southwest.

On April 7, 2026, the Company's 34 Network Operations Control Customer Planners represented by the International Association of Machinists and Aerospace Workers ("IAM") voted to ratify the tentative agreement reached on March 27, 2026, as part of the accretion process to join an existing IAM-represented collective bargaining unit. The newly ratified agreement becomes amendable in December 2027.

Operating Revenues

Total operating revenues for second quarter 2026 increased by $1.2 billion, or 16.4 percent, year-over-year, to achieve an all-time quarterly Company record of $8.4 billion, despite a $285 million decrease related to a breakage adjustment, which was treated as a special item and excluded from the Company's presentation of non-GAAP results. See Note Regarding Use of Non-GAAP Financial Measures and see Notes 1 and 5 to the unaudited Condensed Consolidated Financial Statements for further information. Passenger revenues for second quarter 2026 increased by $1.1 billion, or 16.9 percent, year-over-year, driven primarily by a higher percentage of Customers purchasing higher fare categories as a result of the enhanced fare structure, coupled with an increase in new ancillary products implemented by the Company, including bag fee revenues for first and second checked bags for tickets purchased on or after May 28, 2025, and operating assigned and extra legroom seating for travel beginning January 27, 2026, which includes the co-brand impact associated with those initiatives. Other revenues for second quarter 2026 increased by $64 million, or 11.2 percent, year-over-year, driven primarily by improved retail spend on the Company's co-branded credit cards. Second quarter 2026 RASM was 17.91 cents, finishing 16.2 percent higher than second quarter 2025. The unit revenue increase was primarily due to a 15.4 percent increase in yield as a result of broad demand strength and strong Customer engagement with the Company's enhanced product offering, including an increase in ancillary revenues, along with a 0.8 point year-over-year increase in Load factor. Second quarter 2026 RASM, excluding special items, was 18.51 cents, finishing 20.1 percent higher than second quarter 2025.

| Total | 17.30 | 14.94 | 2.36 | 15.8% |

Operating expenses per ASM for second quarter 2026 increased by 15.8 percent compared with second quarter 2025, primarily due to an increase in Aircraft fuel and related taxes expense and Salaries, wages, and benefits expense. Operating expenses per ASM for second quarter 2026, excluding Aircraft fuel and related taxes expense, profit sharing, and special items (a non-GAAP financial measure), increased 3.4 percent, compared with second quarter 2025, primarily due to wage rate inflation in Salaries, wages, and benefits expense in 2026. See Note Regarding Use of Non-GAAP Financial Measures and the Reconciliation of Reported Amounts to Non-GAAP Financial Measures for additional detail regarding non-GAAP financial measures.

Salaries, wages, and benefits expense for second quarter 2026 increased by $237 million, or 7.3 percent, compared with second quarter 2025. On a per ASM basis, second quarter 2026 Salaries, wages, and benefits expense increased 7.2 percent, compared with second quarter 2025. On a dollar and per ASM basis, the majority of the increase was due to step/pay rate increases and related benefits for the Company's workforce.

Aircraft fuel and related taxes expense for second quarter 2026 increased by $889 million, or 67.0 percent, compared with second quarter 2025. On a per ASM basis, second quarter 2026 Aircraft fuel and related taxes expense increased 66.1 percent. On a dollar and per ASM basis, the increase was primarily attributable to increased jet fuel prices, particularly due to recent market disruptions and worldwide geopolitical events. The following table provides more information on the Company's fuel costs per gallon, including the impact of fuel hedging net premium expense associated with previously terminated fuel derivative contracts:

| Line item | Three months ended June 30, 2026 | Three months ended June 30, 2025 |
| --- | --- | --- |
| Fuel costs per gallon | $3.92 | $2.32 |
| Fuel hedging premium expense (in millions) | $29 | $36 |
| Fuel hedging premium expense per gallon | $0.05 | $0.06 |

(a) Includes amounts reclassified from AOCI associated with hedges previously terminated. See Notes 3 and 4 to the unaudited Condensed Consolidated Financial Statements for further information on the Company's derivative instruments and AOCI, respectively.

The Company's second quarter 2026 available seat miles per gallon ("fuel efficiency") increased 1.3 percent, year-over-year, with the improvement primarily due to operating more -8 aircraft, the Company's most fuel-efficient aircraft, as a percentage of its fleet. The continued deliveries of MAX aircraft are expected to remain critical to the Company's efforts to modernize its fleet.

Maintenance materials and repairs expense for second quarter 2026 decreased by $37 million, or 11.2 percent, compared with second quarter 2025. On a per ASM basis, Maintenance materials and repairs expense decreased 11.4 percent compared with second quarter 2025. On a dollar and per ASM basis, the decrease was primarily due to a decrease in -700 engine shop visits.

Landing fees and airport rentals expense for second quarter 2026 increased by $69 million, or 12.2 percent, compared with second quarter 2025. On a per ASM basis, Landing fees and airport rentals expense increased 11.6

percent, compared with second quarter 2025. On a dollar and per ASM basis, approximately 50 percent of the increase was attributable to an increase in airport rental expense throughout the network driven by the higher rates charged by airports for leased space, approximately 25 percent of the increase was due to higher landing fees throughout the network driven by increased usage of the heavier -8 aircraft as well as higher rates, and the remaining increase was primarily due to receiving fewer favorable settlements and credits from various airports in 2026.

Depreciation and amortization expense for second quarter 2026 increased by $2 million, or 0.5 percent, compared with second quarter 2025. On a per ASM basis, Depreciation and amortization expense remained flat compared with second quarter 2025. On a dollar basis, this increase was primarily due to approximately $40 million in increased depreciation as a result of new assets acquired and placed into service, including aircraft, technology, and ground equipment, which was mostly offset by a $25 million decrease in depreciation as a result of a change in estimate for certain airframe and engine assets due to prevailing market conditions and a $16 million reduction due to aircraft and related assets that were retired and/or became fully depreciated since second quarter 2025.

Other operating expenses for second quarter 2026 decreased by $32 million, or 2.8 percent, compared with second quarter 2025. Included within this line item was aircraft rentals expense in the amounts of $75 million and $80 million for the three-month periods ended June 30, 2026 and 2025, respectively. On a per ASM basis, Other operating expenses decreased 2.9 percent, compared with second quarter 2025. On a dollar and per ASM basis, the decrease was primarily due to higher year-over-year gains on the disposition of assets, primarily previously retired engines and aircraft, partially offset by an increase in revenue-related expenses driven by increased credit card transactions, the Company's free inflight WiFi offering, and higher Employee-related expenses driven by redeye flying.

Non-Operating Expenses (Income)

Interest expense for second quarter 2026 increased by $25 million, or 64.1 percent, compared with second quarter 2025, primarily due to various debt financing transactions executed since second quarter 2025. See Note 10 to the unaudited Condensed Consolidated Financial Statements for further information.

Interest income for second quarter 2026 decreased by $21 million, or 38.9 percent, compared with second quarter 2025, primarily due to lower investment balances and a lower average interest rate in the Company's total investment portfolio.

Other (gains) losses, net, for second quarter 2026 increased by $13 million, or 48.1 percent, compared with second quarter 2025, primarily related to impacts from the Company's nonqualified benefit plan obligations driven by volatility in the stock market.

Income Taxes

The Company's effective tax rate was 23.8 percent in second quarter 2026, compared with 23.9 percent in second quarter 2025.

(a) Represents a change in breakage revenue estimate related to non-expiring flight credits the Company issued to Passengers between July 2022 and December 2025. Due to higher-than-projected Customer redemptions of these non-expiring flight credits, along with updated projections of future redemptions, the Company has revised its estimates with regards to the

remaining non-expiring flight credits that remain available for redemption. See Notes 1 and 5 to the unaudited Condensed Consolidated Financial Statements.

(b) Includes amounts reclassified from AOCI associated with hedges previously terminated. See Note 3 to the unaudited Condensed Consolidated Financial Statements for further information.

(c) Represents Employee severance and other related payments resulting from corporate workforce reductions.

(d) Tax amounts for each individual special item are calculated at the Company's effective rate for the applicable period and totaled in this line item.

(a) Net adjustment to reflect all aircraft in fleet as owned (i.e., the impact of eliminating aircraft rent expense and replacing with estimated depreciation expense for those same aircraft). The Company makes this adjustment to enhance comparability to other entities that have different capital structures by utilizing alternative financing decisions.

(b) Calculated as an average of the five most recent quarter end balances or remaining obligations. The Net present value of aircraft operating leases represents the assumption that all aircraft in the Company’s fleet are owned, as it reflects the remaining contractual commitments discounted at the Company's estimated incremental borrowing rate as of the time each individual lease was signed.

(c) The Equity adjustment in the denominator adjusts for the cumulative impacts, in Accumulated other comprehensive income and Retained earnings, of gains and/or losses that will settle in future periods, including those associated with the Company's terminated fuel hedges. The current period impact of these gains and/or losses is reflected in the Net impact from fuel contracts in the numerator.

(d) The GAAP twelve month rolling tax rate as of June 30, 2026, was 21.5 percent, and the Non-GAAP twelve month rolling tax rate was 22.4 percent. See Note Regarding Use of Non-GAAP Financial Measures for additional information.

(e) The GAAP twelve month rolling tax rate as of June 30, 2025, was 22.3 percent, and the Non-GAAP twelve month rolling tax rate was 22.6 percent. See Note Regarding Use of Non-GAAP Financial Measures for additional information.

Note Regarding Use of Non-GAAP Financial Measures

The Company's unaudited Condensed Consolidated Financial Statements are prepared in accordance with GAAP. These GAAP financial statements include (i) unrealized noncash reclassifications, as a result of accounting requirements and elections previously made under accounting pronouncements relating to derivative instruments and hedging and (ii) other charges and benefits the Company considers unusual and/or infrequent in nature and thus may make comparisons to its prior or future performance difficult.

Accordingly, the Company also provides financial information in this filing that was not prepared in accordance with GAAP and should not be considered as a substitute for the information prepared in accordance with GAAP. The Company provides supplemental non-GAAP financial information (also referred to as "excluding special items"). Management believes special items can distort the trends associated with the Company’s ongoing performance. Therefore, management utilizes non-GAAP financial measures to evaluate the Company’s financial performance, anticipate future operating results, and assess trends without the impact of items that can vary significantly from period to period. The following measures are often provided, excluding special items, and are utilized by the Company’s management, analysts, and investors to enhance comparability of year-over-year results, as well as to industry trends: Operating revenues, non-GAAP; Total operating expenses, non-GAAP; Operating expenses, non-GAAP excluding Aircraft fuel and related taxes expense; Operating expenses, non-GAAP excluding Aircraft fuel and related taxes expense and profit sharing; Operating income, non-GAAP; Adjusted Operating income, non-GAAP; Income before income taxes, non-GAAP; Provision for income taxes, net, non-GAAP; Net income, non-GAAP; Net income per share, diluted, non-GAAP; Operating revenues per ASM, non-GAAP (cents); Operating expenses per ASM, non-GAAP, excluding Aircraft fuel and related taxes expense and profit sharing (cents); Return on invested capital, non-GAAP; adjusted operating margin; and adjusted net margin.

For the periods presented, special items include:

1.Charges associated with tentative litigation settlements regarding paid short-term military leave to certain Employees;

2.Expenses associated with professional advisory fees related to the Company's implementation of its comprehensive transformational plan;

3.Charges associated with Employee severance and other related payments resulting from corporate workforce reductions;

4.Reversal of breakage revenue recorded in prior years related to a portion of non-expiring flight credits issued to Customers between July 2022 and December 2025 that have either been redeemed or are expected to be redeemed in future periods;

5.Non-cash impairment charges to remove certain assets from the unaudited Condensed Consolidated Balance Sheet that are no longer in use;

6.Expenses associated with incremental professional advisory fees related to activist investor activities, which were not budgeted by the Company or associated with the ongoing operation of the airline;

7.Incremental expense associated with a voluntary separation program that allowed eligible Employees the opportunity to voluntarily separate from the Company in exchange for severance, medical/dental coverage for a specified period of time, and travel privileges based on years of service; and

8.A charge associated with a settlement reached with the Department of Transportation ("DOT") as a result of the Company's December 2022 operational disruption.

The Company has also provided its calculation of return on invested capital ("ROIC"), which is a measure of financial performance used by management to evaluate its investment returns on capital. ROIC is not a substitute for financial results as reported in accordance with GAAP and should not be utilized in place of such GAAP results. Return on invested capital is not a measure defined by GAAP. It is calculated by the Company, in part, using non-GAAP financial measures, which include charges or benefits that are deemed "special items." As noted above, the Company believes "special items" make it difficult to compare to prior periods, anticipated future periods, or industry trends since these items cannot be reliably predicted or estimated. The Company believes non-GAAP ROIC is a meaningful measure because it quantifies the Company's effectiveness in generating returns relative to the capital it has invested in its business. Although ROIC is commonly used as a measure of capital efficiency, definitions of return on invested capital differ; therefore, the Company is providing an explanation of its calculation

for non-GAAP return on invested capital in the accompanying reconciliation in order to allow investors to compare and contrast its calculation to the calculations provided by other companies.

Liquidity and Capital Resources

Net cash provided by operating activities was $530 million for the three months ended June 30, 2026, compared with $401 million provided by operating activities in the same prior year period. Net cash provided by operating activities was $1.9 billion for the six months ended June 30, 2026 compared with $1.3 billion provided by operating activities in the same prior year period. Historically, operating cash inflows are primarily derived from selling tickets for future flights and providing air transportation to Customers. The vast majority of tickets are purchased prior to the day on which travel is provided and, in some cases, several months before the anticipated travel date. Operating cash outflows are related to the recurring expenses of airline operations. The operating cash flows for the six months ended June 30, 2026, were largely impacted by the Company's net results (as adjusted for noncash items), a $97 million profit-sharing contribution related to 2025 results pursuant to the Company's Retirement Savings Plan, and a $1.0 billion increase in Air traffic liability driven by seasonal bookings for future travel. The operating cash flows for the six months ended June 30, 2025, were largely impacted by the Company's net results (as adjusted for noncash items), a $103 million profit-sharing contribution related to 2024 results pursuant to the Company's Retirement Savings Plan, and a $55 million increase in Air traffic liability driven by higher ticket sales. Net cash provided by operating activities is primarily used to finance capital expenditures, repay debt, provide Shareholder returns, and provide working capital.

Net cash used in investing activities totaled $560 million during the three months ended June 30, 2026, compared with $882 million used in investing activities in the same prior year period. Net cash used in investing activities totaled $1.0 billion during the six months ended June 30, 2026, compared with $259 million used in investing activities in the same prior year period. Investing activities in both years included Capital expenditures, as well as proceeds from the sale of various capital assets, and the prior year also included changes in the balance of the Company's short-term and noncurrent investments. During the six months ended June 30, 2026, gross Capital expenditures were $1.4 billion, and the Company had $450 million proceeds from sales of assets, compared with $1.2 billion gross Capital expenditures, and $51 million proceeds from sales of assets in the same prior year period. Capital expenditures increased, year-over-year, largely due to an increase in average delivery payment balances for scheduled future aircraft deliveries during the six months ended June 30, 2026, compared with the same prior year period. Proceeds from sales increased, year-over-year, due to the timing and volume of various aircraft and engine sales in the six months ended June 30, 2026, compared with June 30, 2025.

The Company expects its 2026 net capital spending to be toward the low end of, or below, the $3.0 billion to $3.5 billion range based on its expectation of 64 -8 aircraft deliveries in 2026, with the remainder representing non-aircraft capital spending, partially offset by proceeds from sales of assets. The Company continues to plan for approximately 60 aircraft retirements in 2026.

Net cash provided by financing activities was $493 million during the three months ended June 30, 2026, compared with $4.2 billion used in financing activities for the same prior year period. Net cash used in financing activities was $383 million during the six months ended June 30, 2026, compared with $5.0 billion used in financing activities for the same prior year period. During the six months ended June 30, 2026, the Company paid $181 million in cash dividends to Shareholders related to the first quarter 2026 and fourth quarter 2025 declarations. The second quarter 2026 dividend declaration of $87 million was paid in July 2026. Additionally, the Company expended $1.25 billion to repurchase the Company's outstanding common stock through accelerated share repurchase programs (each, an "ASR") and open market share repurchases during the six months ended June 30, 2026. The repurchases of common stock amounts in the unaudited Consolidated Statement of Cash Flows may differ from the unaudited Consolidated Statement of Stockholder's Equity due to the timing of excise taxes incurred and subsequent payment on share repurchases, net of issuances. During the six months ended June 30, 2026, the Company entered into the Term Loan Credit Agreement with a third-party bank, providing for the $500 million senior secured Term Loan Credit Facility that was drawn in full on March 11, 2026. On May 19, 2026, the Company executed an upsize of the Term Loan Facility for $1 billion of incremental term loan commitments. The Term Loan Facility matures in full on March 11, 2029. Additionally, the Company prepaid the $426 million outstanding balance of the note associated with the PSP3 Payroll Support Program in April 2026. See Note 10 to the unaudited Condensed Consolidated Financial Statements for further information. The Company may engage in early debt repurchases from time to time at its discretion;

however, no other potential early future repurchases are included in the Company's Current maturities of long-term debt unless otherwise disclosed as of June 30, 2026. During the six months ended June 30, 2025, the Company paid $210 million in cash dividends to Shareholders related to the first quarter 2025 and fourth quarter 2024 declarations. Additionally, the Company expended $2.25 billion to repurchase the Company's outstanding common stock through ASRs.

On July 23, 2025, the Board approved a $2.0 billion share repurchase authorization of the Company's common stock. During the six months ended June 30, 2026, the Company repurchased 28,429,822 shares of its common stock, all of which occurred during first quarter of 2026. The Company did not repurchase any shares during second quarter of 2026. As of June 30, 2026, approximately $450 million remained available under the Company’s share repurchase authorization. See Part II, Item 2 for further information on the Company's share repurchases. These purchases were recorded as treasury share repurchases for purposes of calculating earnings per share. Subject to certain conditions, repurchases may be made in accordance with applicable securities laws in open market or private, including accelerated repurchase transactions from time to time, depending on market conditions.

The Company is a "well-known seasoned issuer" and currently has an effective shelf registration statement registering an indeterminate amount of debt and equity securities for future sales. The Company intends to use the proceeds from any future securities sales off this shelf registration statement for general corporate purposes.

The Company has access to $1.5 billion under the Amended Credit Agreement, which expires in August 2028. For the six months ended June 30, 2026 and 2025 there were no amounts outstanding under the Amended Credit Agreement. See Note 10 to the unaudited Condensed Consolidated Financial Statements for further information.

As of June 30, 2026, the Company carried a working capital deficit of approximately $6.8 billion, in which its current liabilities exceed its current assets. This is common within the airline industry and is primarily due to the nature of the Air traffic liability account, which is related to advance ticket sales, unused flight credits available to Customers, and loyalty deferred revenue, which are performance obligations for future Customer flights, do not require future settlement in cash, and are mostly nonrefundable. See Note 5 to the unaudited Condensed Consolidated Financial Statements for further information.

The Company believes it has various options available to meet its capital and operating commitments, including unrestricted cash of $3.8 billion as of June 30, 2026, and anticipated future internally generated funds from operations. The Company continues to have a large base of unencumbered aircraft and other related assets with a net book value of approximately $15.7 billion. The Company regularly evaluates its capital structure to efficiently manage financial risks, liquidity access, and cost of capital. The Company may consider, from time to time, additional financing arrangements, including secured or unsecured debt, as appropriate. In March 2026, the Company entered into the Term Loan Facility and subsequently, in May 2026, executed an upsize for incremental loan commitments. The commitments are secured by a grant of a security interest in certain aircraft and related assets with a minimum collateral coverage ratio requirement. In addition, the Company continues to maintain investment-grade credit ratings by all three major credit agencies (Moody's, S&P Global, and Fitch).

As of July 23, 2026, for the years 2026 through 2031, the Company has firm orders with Boeing for 479 MAX aircraft (264 -7s and 215 -8s), less 25 -8 aircraft received to date in 2026, and 138 MAX options (-7s or -8s). The contractual order book as of July 23, 2026, does not include the impact of delivery delays and is subject to change based on ongoing discussions with Boeing and their production capability. See Note 9 to the unaudited Condensed Consolidated Financial Statements for further information.

The following table details information on the aircraft in the Company's fleet as of June 30, 2026:

| Type | Seats | Average Age (Yrs) | Number of Aircraft | Number Owned | Number Leased |
| --- | --- | --- | --- | --- | --- |

Cautionary Statement Regarding Forward-Looking Statements

This Form 10-Q contains “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934 ("Exchange Act").

- the cost and effects of the actions of activist shareholders; and
- other factors as set forth in the Company's filings with the Securities and Exchange Commission (the "SEC"), including the detailed factors discussed under the heading “Risk Factors” in the Company's Annual Report on Form 10-K for the year ended December 31, 2025.

Caution should be taken not to place undue reliance on the Company's forward-looking statements, which represent the Company's views only as of the date this report is filed. The Company undertakes no obligation to update publicly or revise any forward-looking statement, whether as a result of new information, future events or otherwise.

## Item 3. Quantitative and Qualitative Disclosures About Market Risk

Hedging and Aircraft Fuel Risk

Changes in fuel prices could materially affect the Company’s results of operations. As discussed in Note 3 to the unaudited Condensed Consolidated Financial Statements, the Company discontinued its fuel hedging program in

2025. During second quarter 2025, the Company terminated its remaining portfolio of fuel hedging contracts, which were scheduled to settle through 2027, to effectively close its fuel hedging portfolio and program. Consequently, the Company is fully exposed to fluctuations in fuel prices, as is common in the airline industry. The Company currently expects to consume approximately 532 million gallons of jet fuel in the third quarter of 2026. Based on this anticipated usage, a change in jet fuel prices of one-cent per gallon would impact the Company’s Aircraft fuel and related taxes expense by $5.3 million for third quarter 2026.

As of June 30, 2026, the Company had no cash collateral provided to or held from derivative counterparties and thus had no cash collateral exposure. See Note 3 to the unaudited Condensed Consolidated Financial Statements.

Financial Market Risk

The Company currently has agreements with organizations that process credit card transactions arising from purchases of air travel tickets by its Customers utilizing American Express, Discover, and MasterCard/VISA. Credit card processors have financial risk associated with tickets purchased for air travel because the processor generally forwards the cash related to the purchase to the Company soon after the purchase is completed, but the air travel generally occurs after that time; therefore, the processor will have liability if the Company does not ultimately provide the air travel. Under these processing agreements, and based on specified conditions, increasing amounts of cash reserves could be required to be posted with the counterparty. There was no cash reserved for this purpose as of June 30, 2026.

A majority of the Company’s sales transactions are processed by Chase Paymentech. Should Customer chargebacks processed by Chase Paymentech reach a certain level, cash proceeds from advance ticket sales could be held back and used to establish a reserve account to cover such chargebacks and any other Customer-disputed charges that might occur. Additionally, cash reserves are required to be established if the Company’s credit rating falls to specified levels below investment grade. Cash reserve requirements are based on the Company’s public debt rating and a corresponding percentage of the Company’s Air traffic liability. As of June 30, 2026, no cash holdbacks were in place.

See Item 7A "Quantitative and Qualitative Disclosures About Market Risk" in the Company's Annual Report on Form 10-K for the year ended December 31, 2025, for further information about market risk, and Note 3 to the unaudited Condensed Consolidated Financial Statements in this Form 10-Q for further information about the Company's derivative instruments.

The Company maintains disclosure controls and procedures (as defined in Rule 13a-15(e) of the Exchange Act) designed to provide reasonable assurance that the information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the SEC's rules and forms. These include controls and procedures designed to ensure that this information is accumulated and communicated to the Company's management, including its Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. The Company's management, with the participation of the Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of the Company's disclosure controls and procedures as of June 30, 2026. Based on this evaluation, the Company's Chief Executive Officer and Chief Financial Officer have concluded that the Company's disclosure controls and procedures were effective as of June 30, 2026, at the reasonable assurance level.

Changes in Internal Control over Financial Reporting

There were no changes in the Company’s internal control over financial reporting (as defined in Rule 13a–15(f) under the Exchange Act) during the fiscal quarter ended June 30, 2026, that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

PART II. OTHER INFORMATION

## Item 1. Legal Proceedings

See Item 3. Legal Proceedings in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025 for a description of material legal proceedings. The legal proceedings described below are included in this Quarterly Report on Form 10-Q to disclose material updates or developments in the matter. Except as presented below and in the Company's Quarterly Report on Form 10-Q for the quarter ended March 31, 2026, there have been no material changes to the legal proceedings disclosed in Item 3. Legal Proceedings in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025.

On January 7, 2019, a complaint alleging a violation of the federal Uniformed Services Employment and Reemployment Rights Act (“USERRA”) and seeking a certification as a class action was filed against the Company in the United States District Court for the Northern District of California. The complaint alleges that the Company violates section 4316(b) of USERRA because it does not provide paid “short-term” military leave (i.e., a military leave of 14 days or fewer) but does provide paid jury duty leave, bereavement leave, and sick leave, which the plaintiff alleges are “comparable” forms of leave under USERRA and its implementing regulations. The complaint seeks declaratory and injunctive relief, damages, liquidated damages, interest, and attorneys’ fees, expert fees, and litigation costs. On February 3, 2021, the Court granted the plaintiff’s motion for class certification and issued an order certifying a class comprised of current or former Employees who, during their employment with the Company at any time from October 10, 2004, through the date of judgment in this action, have taken short-term military leave and were subject to a collective-bargaining agreement, except for Employees subject to the Transport Workers Union Local 550 agreement covering meteorologists. On January 11, 2022, the Court granted the parties’ stipulated request to vacate the trial date as the Department of Defense had not yet produced the class members’ military pay and service records pursuant to the Company’s third-party subpoena. On August 18, 2022, the Court entered an order that effectively stayed the action, except for attention to the third-party subpoena, until after the Ninth Circuit issued its opinion in the matter of Clarkson v. Alaska Airlines, Inc. and Horizon Industries, Inc., an appeal from an order by the United States District Court for the Eastern District of Washington granting summary judgment in defendants’ favor on substantially the same claims at issue in this action. The Ninth Circuit issued its order in Clarkson on February 1, 2023, reversing the district court’s grant of summary judgment and remanding the Clarkson case to the District Court with instructions to consider the “pay during leave” issue in the first instance. The Company has received the military pay and service records. On October 29, 2024, the Company filed a motion to decertify the class, which was then fully briefed and set for hearing. On February 13, 2025, the parties filed a notice of settlement advising the Court that they reached a settlement in principle, and the parties made a stipulated request for the Court to vacate the case schedule, including the hearing on the Company's decertification motion, and to set a deadline of June 19, 2025, for the filing of either a motion for preliminary approval of the class settlement or a status update about the timing of the remaining steps in the settlement process. The Court granted the stipulation on February 14, 2025. On June 20, 2025, the Court granted the parties’ stipulated request to continue the deadline for filing a motion for preliminary approval of the class settlement and the Court reset the deadline for August 21, 2025. On September 25, 2025, plaintiffs filed a motion for preliminary approval of the settlement class. The class proposed in the settlement modifies the class definition to use an end date of January 1, 2026 (rather than treating the date of judgment as the end date). The settlement includes an $18.5 million settlement fund and prospective relief that includes a differential pay benefit for up to ten days of military leave per year, which will remain in place for at least five years once initiated. On December 11, 2025, the Court granted preliminary approval of the settlement. On May 12, 2026, the Court conducted a final approval hearing. On May 19, 2026, the Court granted final approval of the settlement, entered final judgment, and closed the case.

On December 27, 2019, a former customer service agent at Oakland International Airport, filed a putative class action complaint in the Superior Court of California, for the County of Santa Clara, against the Company alleging the following seven claims under the California Labor Code and Business & Professions Code: (1) failure to provide meal periods; (2) failure to provide rest periods; (3) failure to pay hourly wages; (4) failure to provide accurate wage statements; (5) failure to timely pay all final wages; (6) unfair competition; and (7) civil penalties for the foregoing. Plaintiff filed a First Amended Complaint on October 15, 2021, that asserted the same causes of

action and added a named plaintiff. The First Amended Complaint primarily seeks unpaid wages, interest thereon, and associated civil and statutory penalties, along with attorneys’ fees and costs. On February 26, 2025, the Court granted class certification as to the first cause of action for failure to provide meal periods, denied certification on the second through fourth causes of action, and granted certification on the fifth and sixth causes of action only insofar as they are predicated on the first cause of action. The certified class consists of all of the Company’s non-exempt ground employees in California who worked a shift in excess of five hours for the time period between October 24, 2014, forward. On April 17, 2025, the Company filed a summary judgment motion arguing that Plaintiffs’ first cause of action, and all causes of action predicated thereon, failed as a matter of law. The motion was granted on July 25, 2025. Judgment was entered in favor of the Company on September 2, 2025, and Plaintiffs filed a notice of appeal on September 4, 2025. On May 6, 2026, Plaintiffs filed their opening appellate brief. The Company’s answering brief is due on August 4, 2026. The Company intends to continue to vigorously defend itself in all respects.

Two complaints alleging violations of federal securities laws and seeking certification as a class action were filed (on January 10, 2023, and March 13, 2023, respectively) against the Company and certain of its officers in the United States District Court for the Southern District of Texas in Houston. The complaints seek damages on behalf of a putative class of persons who purchased or otherwise acquired the Company's common stock between June 13, 2020, and December 31, 2022. The complaints assert claims under Sections 10(b) and 20 of the Exchange Act and allege that the Company made material misstatements to investors regarding the Company's internal technology and alleged vulnerability to large-scale flight disruptions. The complaints generally seek money damages, pre-judgment and post-judgment interest, and attorneys' fees and other costs. The deadline in the first of these two cases to file a motion seeking appointment of lead plaintiff was March 13, 2023; four separate motions were filed, and three of the parties seeking appointment contested the issue. On July 17, 2023, the Court signed an order consolidating the two federal securities cases into the first-filed suit and also appointed plaintiff Michael Berry as lead plaintiff in the consolidated case, with his counsel of record to serve as lead counsel and liaison counsel. On September 15, 2023, the lead plaintiff filed an amended complaint that expanded the class period to include persons who purchased or otherwise acquired the Company's common stock between February 4, 2020, and March 14, 2023, while continuing to assert claims under Sections 10(b) and 20 of the Exchange Act based on alleged misstatements regarding the Company's internal technology and alleged vulnerability to large-scale flight disruptions. On November 20, 2023, the Company and the individual defendants filed a motion to dismiss the amended complaint for failure to state a claim. The plaintiffs filed an opposition brief on January 26, 2024. The Company and the individual defendants filed a reply brief on February 23, 2024. On December 5, 2024, the United States District Court for the Southern District of Texas denied the motion to dismiss on the basis that "the issues are better suited for a summary judgment motion after the parties have had the opportunity to engage in discovery." On December 21, 2024, the Company moved for reconsideration of the December 5, 2024, order and, in the alternative, for permission to pursue an interlocutory appeal. The plaintiffs opposed both requests for relief. On April 3, 2025, the United States District Court for the Southern District of Texas conducted a hearing on the Company’s motion for reconsideration and requested the parties to confer and submit an agreed post-hearing briefing schedule in order for the Court to evaluate and determine the sufficiency of the allegations in plaintiffs’ amended complaint in accordance with the Private Securities Litigation Reform Act. The parties submitted their respective briefing on these issues. On March 31, 2026, the Court signed a memorandum opinion and order that granted defendants’ motion for reconsideration, withdrew the Court’s prior order denying defendants’ motion to dismiss plaintiffs’ complaint, and granted defendants’ motion to dismiss plaintiffs’ complaint without prejudice. The order granted plaintiffs leave to amend the complaint under specified parameters, including that any amended complaint be filed by April 24, 2026, and be accompanied by a synopsis of no more than ten pages, explaining how the amendments address the grounds for dismissal stated in the Court’s March 31 order. The plaintiffs did not amend their complaint, but rather filed a motion for entry of final judgment on May 1, 2026. The Court entered final judgment on May 20, 2026, dismissing all claims with prejudice, and the plaintiffs filed their notice of appeal the same day. The Fifth Circuit Court of Appeals has entered a briefing schedule, and the plaintiffs’ opening appeal brief is currently due to be filed on August 25, 2026. On July 20, 2026, the plaintiffs filed a request pursuant to Fifth Circuit practice for a 30-day extension until September 24, 2026, to file their response, which the Defendants do not oppose. The Defendants intend to file a response brief in support of the District Court’s dismissal order. The Company denies all allegations

of wrongdoing in the complaint, believes the plaintiffs' positions below and on appeal are without merit, and intends to vigorously defend itself in all respects, including in opposing the appeal.

Starting on or about January 24, 2023, the Company’s senior officers and the Board received multiple derivative demand letters from legal counsel for purported Southwest Shareholders demanding that the Board investigate claims, initiate legal action, and take remedial measures in connection with the service disruptions occurring in December 2022. Generally, the demand letters broadly assert that the Company’s directors and senior officers did not make sufficient investments in internal technology systems to prevent large-scale flight disruptions, did not exercise sufficient oversight over the Company’s operations, approved or received unwarranted compensation, caused the Company to make materially misleading public statements, and breached their fiduciary duties to the Company. Additionally, since January 27, 2023, the Company has received multiple letters from counsel for purported Southwest Shareholders making statutory demands for the production of various books and records of the Company, purportedly in an effort to investigate possible derivative claims similar to those made the subject of the derivative demands discussed above. On June 13, 2023, a shareholder derivative suit was filed against certain of the Company’s current and former officers and directors in the 14th Judicial District Court of Dallas County, Texas, asserting claims for damages from alleged breach of fiduciary duty, waste of corporate assets, and unjust enrichment derivatively on the Company’s behalf against the individual defendants based on similar factual allegations as contained in the demand letters and in the federal class action complaints. On June 15, 2023, a second shareholder derivative suit was filed against certain of the Company’s current and former officers and directors in the United States District Court for the Northern District of Texas, asserting claims under Section 14(a) of the Exchange Act and for damages from alleged breach of fiduciary duty, indemnification, and unjust enrichment derivatively on the Company’s behalf against the individual defendants based on similar factual allegations as contained in the demand letters and in the federal class action complaints. On November 14, 2023, a third shareholder derivative suit was filed in the 134th Judicial District of Dallas County, Texas, by some of the same counsel involved in the June 13, 2023, suit against the same defendants in that suit and making allegations of the same operative facts and claims. On June 18, 2024, a fourth shareholder derivative suit was filed in the 101st Judicial District Court of Dallas County, Texas, asserting substantially similar claims as in the first two state court derivative suits. On June 26, 2024, a fifth shareholder derivative suit was filed in the United States District Court for the Northern District of Texas, asserting substantially similar claims as in the first federal derivative suit. On July 18, 2024, a sixth shareholder derivative suit was filed in the United States District Court for the Northern District of Texas, asserting substantially similar claims as in the first federal derivative suit (together with the previous demand letters and shareholder derivative suits, the “Derivative Actions and Demands”).

The Company and the Board have addressed the Derivative Actions and Demands in accordance with the applicable Texas statutes governing such demands and litigation. Pursuant to those statutes, a committee of independent and disinterested directors (the "Special Litigation Committee") was appointed to conduct an inquiry regarding the allegations in the Derivative Actions and Demands. The state court cases were consolidated into one state court case, and the federal cases were later consolidated into one federal case.

As described above, pursuant to the applicable Texas statutes governing derivative demands and litigation, the Special Litigation Committee was duly appointed to conduct an inquiry regarding the claims and allegations asserted in the Derivative Actions and Demands. The Derivative Actions and Demands were all stayed, formally or by agreement, pending the outcome of the investigation by the Special Litigation Committee. On September 19, 2024, the Special Litigation Committee formally reported its findings and resolution concerning its investigation of the Derivative Actions and Demands, which began in July 2023 and concluded with the September 19, 2024 report and resolution, which in turn were delivered to the Company and its Board on September 23, 2024. The Special Litigation Committee retained two law firms to represent the Special Litigation Committee in connection with the Special Litigation Committee’s investigation of the Derivative Actions and Demands and the Special Litigation Committee’s review and assessment of evidence gathered in its investigation. The Special Litigation Committee further reported, among other details, upon its appointment, the independence and disinterestedness of its members, the Special Litigation Committee’s investigative processes, including meetings, scope of investigation, volume of documents reviewed, numbers of witnesses interviewed, other presentations received, review and analysis of evidence and applicable legal standards, work with its counsel, and findings and preparation of the final report and

resolution of the Special Litigation Committee. Based upon the Special Litigation Committee report and the conclusions reached therein, the Special Litigation Committee, consistent with its appointment and delegated authority, unanimously adopted a resolution (i) determining that it is not in the best interests of the Company or its Shareholders to pursue the relief requested in the Derivative Actions and Demands; (ii) determining that it is in the best interests of the Company and its Shareholders to reject the Derivative Actions and Demands; (iii) determining that it is in the best interests of the Company and its Shareholders for the Company to move to dismiss the Derivative Actions and Demands; and (iv) instructing that the Company and counsel take all further actions necessary to implement the resolution. On December 26, 2024, the Board received a seventh demand letter, and on January 31, 2025, received an eighth demand letter, each containing allegations substantially similar to those presented in certain of the prior Derivative Actions and Demands, which are being addressed consistent with applicable Texas law governing such demands. On April 1, 2025, the Company filed a motion to dismiss or stay the consolidated state court derivative actions based on the forum selection clause in the Company’s bylaws and the pendency of the related federal derivative cases. In May 2025, the Company and the plaintiffs in the state court derivative actions filed a joint stipulation and proposed order to stay the state court derivative actions and, among other things, to make a ruling on a motion to dismiss in the federal derivative case binding upon the state court derivative actions. On June 18, 2025, the Company filed a motion to lift the stay in the consolidated federal derivative actions and an accompanying motion to dismiss based on the Special Litigation Committee's report, conclusions, and resolution. The parties have submitted to the Court a stipulation with a proposed schedule pertaining to further briefing and related proceedings in connection with the motion to dismiss. On June 26, 2026, the Court granted Defendants’ motion to lift the stay in this action in order to consider Defendants’ motion to dismiss and initially ordered the plaintiffs to respond to the motion to dismiss. The plaintiffs, with the agreement of Defendants, renewed their request for the Court to enter a scheduling order pertaining to briefing and related discovery and proceedings in connection with the motion to dismiss. On July 17, 2026, the Court signed an order setting forth a discovery and briefing schedule consistent with the limited discovery permitted by Texas Business Organizations Code §21.556. Pursuant to the July 17, 2026 order, the timing for the plaintiffs to file their response to the motion to dismiss and for the Company to file its reply in support of the motion are dependent upon the amount and timing of the limited discovery pursuant to the referenced statute and any motion practice as to the scope of that discovery. The Company intends vigorously to pursue the motion to dismiss.

On January 28, 2025, two participants in the Company’s retirement plans commenced a putative class action in the United States District Court for the Northern District of Texas against the Company, the Board, and certain of the Company’s officers. Plaintiffs purport to represent a class consisting of participants and beneficiaries in the Southwest Airlines Co. Retirement Savings Plan, the Southwest Airlines Co. 401(k) Plan, and the Southwest Airlines Co. ProfitSharing Plan (collectively, the “Plan”) who invested in the Harbor Capital Appreciation Fund from January 28, 2019 “through the date of judgment.” The complaint asserts that defendants mismanaged Plan assets and failed to monitor the Plan in violation of the Employee Retirement Income Security Act (“ERISA”) by, among other things, failing to remove the Harbor Fund as an investment option. The complaint seeks various forms of declaratory and monetary relief as well as attorneys’ fees, interest and other costs. The Company moved to dismiss the complaint for failure to state a claim, and the court denied the motion. On June 10, 2026, the court stayed all proceedings pending a decision by the U.S. Supreme Court in another case, Anderson v. Intel Corp. mv. Pol v Comm., Case No. 25-498, in which the Supreme Court will address the pleading standard for similar ERISA claims challenging investment options offered by a retirement plan. The defendants deny all allegations of wrongdoing, believe the plaintiffs’ claims are without merit, and intend to vigorously defend against these claims.

On April 29, 2025, the Company received a demand letter addressed to the Board, dated April 28, 2025, from a purported Southwest Shareholder contending that the Company’s directors and senior officers breached their fiduciary duties in connection with the Board’s decision to end Southwest’s Bags Fly Free policy and to begin charging passengers for bags. The letter demanded that the Board investigate the circumstances surrounding the policy change and bring suit against individual directors and officers who allegedly breached their duties to the Company. On June 27, 2025, the Company sent a response to the demand letter on behalf of the Board rejecting the allegations and denying them and any other form of wrongdoing. The response letter also noted that the Board approved an amendment and restatement of the Company’s bylaws that, among other things, established a minimum ownership threshold of three percent of Southwest’s outstanding shares in order for a Southwest shareholder to

institute or maintain a derivative proceeding, consistent with the provisions in Texas Senate Bill 29, which was signed into law on May 14, 2025. The response letter further noted that the purported shareholder who sent the demand letter claims to hold only 100 shares of the Company’s stock and thus fell well short of the three percent threshold. On July 10, 2025, the shareholder who sent the demand filed a shareholder derivative complaint in the United States District Court for the Northern District of Texas against various directors and officers of the Company based on the contentions asserted in the demand letter. The suit asserts, among other things, that the decision to change Southwest’s Bags Fly Free policy conflicts with the Company’s prior views regarding the policy and is detrimental to the Company’s business, and that the Company’s directors approved the policy to accede to pressure from large shareholder Elliott Investment Management L.P., to preserve their Board seats, or both, rather than to serve the Company’s interests. The complaint also asserts that the amendment and restatement of the Company’s bylaws is ineffective. On August 25, 2025, the Company and its Board moved to dismiss the derivative complaint and all claims on the grounds, among others, that the suit is barred by Texas Senate Bill 29 and the Company's bylaw passed pursuant thereto requiring a three percent ownership threshold in order for Company shareholders to bring derivative claims. The plaintiff opposed the motion, claiming the purportedly retroactive application of Texas Senate Bill 29 and the Company bylaw are unconstitutional; and the Company filed a reply in support of its motion to dismiss. Additionally, multiple entities sought and were granted leave to file three separate amicus curiae briefs in support of the Company's motion to dismiss and Texas Senate Bill 29; those included one amicus brief each by: (i) the Chamber of Commerce of the United States of America and the Texas Association of Business, (ii) the Alliance for Corporate Excellence, and (iii) Texans for Lawsuit Reform. Finally, in light of the constitutional challenge to Texas Senate Bill 29, on October 3, 2025, the State of Texas, represented by the Office of the Attorney General of Texas, filed a motion to intervene in the case and its own accompanying motion to dismiss the plaintiff's derivative suit and all claims therein as barred by Texas Senate Bill 29. The State of Texas’s motion to intervene was granted, and its motion to dismiss has been fully briefed by both the State and the plaintiff. On March 17, 2026, the District Court signed a memorandum opinion and order granting the defendants’ motion to dismiss and dismissing with prejudice all claims of the plaintiff. Also on March 17, 2026, the Court signed a final judgment dismissing with prejudice all claims of the plaintiff. On April 15, 2026, the plaintiff filed a notice of appeal to the United States Court of Appeals for the Fifth Circuit. On July 13, 2026, the plaintiff filed his opening appeal brief. The Company intends to file a response brief in support of the District Court’s dismissal order. The Company and its Board deny all allegations of wrongdoing, believe the plaintiffs' positions and appeal are without merit, and intend to vigorously defend themselves in all respects, including in opposing the appeal.

> SOUTHWEST AIRLINES CO. AMENDED AND RESTATED 2007 EQUITY INCENTIVE PLAN TERMS AND CONDITIONS PHANTOM SHARE AWARDS (Effective For Awards Granted Beginning on May 6, 2026) By asserting any rights with respect to a Phantom Share Award received pursuant to the Southwest Airlines Co. Amended and Restated 2007 Equity Incentive Plan (the “Plan”) and granted pursuant to the Notice of Grant of Phantom Share Awards with which these Terms and Conditions are attached (the “Notice of Grant”), the recipient of the Award (the “Participant”) will be deemed to have understood and agreed to the terms and conditions of the Plan and the terms and conditions set forth below. Capitalized terms used and not otherwise defined in these Terms and Conditions shall have the meanings assigned to them in the Plan or in the Notice of Grant. 1. Grant of Phantom Shares. (a) Grant. The Company grants to the Participant the number of phantom shares (each, a “Phantom Share”) stated in the Notice of Grant. This grant is subject to these Terms and Conditions and the terms and conditions of the Plan. Each Phantom Share represents the right to receive a cash payment equal to the Fair Market Value of one share of the Company’s Common Stock on the Valuation Date (as defined below). (b) Cash Settlement Only. Despite any contrary provision in the Plan, the Phantom Shares must be settled exclusively in cash. No Common Stock will be issued or delivered to settle this Award. These Phantom Shares do not count against the Plan Limit or any sublimit in Section V of the Plan. (c) No Shareholder Rights. Phantom Shares are not issued and outstanding shares of Common Stock. The Participant has no voting rights, no right to receive dividends, and no other rights of a shareholder for the Phantom Shares. 2. Consideration. The Company grants these Phantom Shares for the services the Participant will provide to the Company and its Affiliates. 3. Vesting. Subject to these Terms and Conditions and the provisions of the Plan, vesting of the Award will be subject to and in accordance with the schedule set forth in the Notice of Grant. Participant must remain in Service through each vesting date and comply with these Terms and Conditions and the Plan. (a) Minimum Vesting Period. Under Plan Section VIII(b), the Phantom Shares must vest over at least three years for time-based vesting or one year for performance-based vesting— unless Section 5 of these Terms and Conditions or the Plan provides otherwise. 4. Valuation and Settlement.

> (a) Valuation Date. The “Valuation Date” for a vested Phantom Share is the date it vests under Section 3 or the date on which vesting is accelerated under these Terms and Conditions. If that date is not a day on which the New York Stock Exchange is open for trading, the Valuation Date is the immediately preceding trading day. (b) Settlement. Within 30 days after each Valuation Date, the Company will pay the Participant the “Settlement Amount.” This amount equals the number of Phantom Shares vesting on that date multiplied by the Fair Market Value of one share of Common Stock on the Valuation Date, minus any withholdings required by Section 9. (c) No Fractional Shares. The Settlement Amount is calculated using only whole Phantom Shares. No fractional Phantom Shares vest, and the Company will not pay cash for any fractional Phantom Share. 5. Termination of Service. (a) General Rule. Except as provided in this Section 5, if the Participant’s Service terminates for any reason, all unvested Phantom Shares are immediately forfeited without payment on the termination date. (b) Death or Disability. If the Participant’s Service terminates because of death or Disability, all unvested Phantom Shares vest in full on the termination date. The Company will pay the Settlement Amount within 30 days. (c) Qualified Retirement. If the Participant’s Service terminates for any reason other than cause, the unvested Phantom Shares remain outstanding and continue to vest under Section 3 as if Service had not terminated, provided that at least 12 months have passed since the Date of Grant and (a) (i) the Participant has completed at least 10 years of continuous Service; and (ii) the Participant’s age plus completed years of continuous Service equal at least 65 at the time of the Participant’s termination of Service; or (b) (i) the Participant has completed at least 5 years of continuous Service; and (ii) the Participant is at least 55 years of age at the time of the Participant’s termination of Service. Settlement of such Phantom Shares will occur in accordance with Section 4. (d) Termination for Cause. If the Participant’s Service is terminated for cause, all Phantom Shares (vested or unvested) that have not been settled are immediately forfeited without payment. (e) Committee Discretion. Despite the rules above, the Committee may waive any Service requirement for any portion of the Phantom Share Award, subject to Section 10. 6. Change in Control. If a Change in Control occurs, the Plan’s provisions govern the Phantom Shares. If the surviving or acquiring entity does not assume or substitute the Phantom Shares, all unvested Phantom Shares vest in full. The Company will pay the Settlement Amount within 30 days after the Change in Control, subject to Section 10. Despite any other provision, if a payment under this section is “deferred compensation” under Section 409A, the Company will pay such payment only if the Change in Control also qualifies as a “change in control event” under Treasury Regulation Section 1.409A-3(i)(5).

> 7. Non-Transferability. The Participant may not transfer, pledge, or encumber the Phantom Shares except by will or the laws of descent and distribution. Any transfer that violates this Section 7 is void. During the Participant’s lifetime, only the Participant or their guardian or legal representative may exercise the rights under these Terms and Conditions. 8. No Right to Continued Service. Neither these Terms and Conditions nor the Plan give the Participant any right to continue in Service. Further, these Terms and Conditions do not limit the right of the Company or any Affiliate to terminate the Participant’s Service at any time and for any reason, with or without cause. 9. Taxes. (a) Withholding. The Company will withhold from the Settlement Amount all federal, state, and local taxes required by law when the Phantom Shares vest or are settled. (b) Participant Responsibility. The Participant is solely responsible for all taxes and penalties related to the Phantom Shares. The Company has made no representations about the tax consequences of this grant. The Participant should consult a tax, financial, or legal advisor. (c) FICA Withholding. Federal Insurance Contributions Act (“FICA”) taxes may become due when the Phantom Shares are no longer subject to a substantial risk of forfeiture, even if that occurs before settlement. The Company may withhold these taxes or require the Participant to pay them when due. 10. Section 409A Compliance. (a) Short-Term Deferral. The Company and Participant intend for these Phantom Shares to qualify for the “short-term deferral” exception under Treasury Regulation Section 1.409A-1(b)(4). These Terms and Conditions must be interpreted and applied accordingly. To the extent the Phantom Shares are “deferred compensation” under Internal Revenue Code Section 409A, these Terms and Conditions must comply with that section. (b) Six-Month Delay for Specified Employees. If the Participant is a “specified employee” under Section 409A at the time of a “separation from service” (as defined in Section 409A), any payment that is “deferred compensation” under Section 409A and otherwise due within six months of that separation will be delayed. The Company will instead pay it on the first business day after the six-month anniversary of the separation (or upon the Participant’s death, if earlier). (c) No Acceleration. Neither the Company nor the Participant may take any action to accelerate or delay any payment in a way that violates Section 409A. (d) Interpretation and Liability. These Terms and Conditions must be interpreted and administered to comply with Section 409A. Any ambiguity must be resolved in a way that avoids Section 409A taxes. Despite any other provision, the Company does not guarantee any specific tax result and is not liable to the Participant if these Terms and Conditions fail to satisfy an exemption or condition of Section 409A. 11. Clawback and Recoupment. The Phantom Shares and any Settlement Amount are subject to the Company’s clawback and recoupment policies. This includes any policy adopted

> to comply with the Dodd-Frank Wall Street Reform and Consumer Protection Act, the Sarbanes- Oxley Act, or any regulations issued under them. 12. Plan Governs. These Terms and Conditions are subject to the terms of the Plan and any rules the Committee adopts to administer it. If these Terms and Conditions conflict with the Plan, the Plan’s provisions govern. 13. Entire Agreement; Amendment. These Terms and Conditions and the Plan are the entire agreement between the Company and the Participant on this subject and supersede all prior agreements or negotiations. These Terms and Conditions may be amended only by a written instrument signed by both the Company and the Participant or—if the Plan permits—by Committee action. 14. Governing Law. Texas law governs these Terms and Conditions, without regard to its conflict-of-laws principles. 15. Notices. A notice under these Terms and Conditions must be in writing. It is considered given when delivered personally or sent by certified or registered mail (return receipt requested) to the Company at its principal executive office or to the Participant at the address in the Company’s records. 16. Severability. If any provision of these Terms and Conditions is held invalid or unenforceable, the remaining provisions remain in effect. The invalid or unenforceable provision will be reformed only as much as necessary to make it valid and enforceable. 17. Successors and Assigns. These Terms and Conditions bind and benefit the Company and its successors and assigns, as well as the Participant, and the Participant’s heirs and personal representatives. 18. Section 16 Compliance. If the Participant is subject to Section 16 of the Securities Exchange Act of 1934, these Terms and Conditions and the related transactions are intended to comply with Rule 16b-3. The Committee may take any action or impose any condition it considers necessary to ensure such compliance. 19. Electronic Acceptance. The Participant may accept these Terms and Conditions electronically, including through the Company’s online equity-plan system. An electronic acceptance is as legally binding as a manual signature. 20. Acknowledgment. By signing these Terms and Conditions or accepting electronically, the Participant agrees that: (a) they have received and reviewed the Plan and these Terms and Conditions and have had the opportunity to ask questions;

> (b) they accept the Phantom Shares under these Terms and Conditions and the terms and conditions of the Plan; (c) they have been advised to consult their own tax, financial, and legal advisors; and (d) the grant of Phantom Shares is voluntary and creates no right to future grants or other benefits.

This Increase Joinder Agreement No. 1 and First Amendment to Credit Agreement (this “Increase Joinder”) is an Increase Joinder referred to in Section 2.24(c) of the Credit Agreement. Unless otherwise defined herein, all capitalized terms used herein that are defined in the Credit Agreement shall have the meanings assigned to such terms in the Credit Agreement. Section 1.

On the Increase Effective Date (as defined below), the Banks referred to on Schedule 1 hereto (each, an “Incremental Bank”) each hereby becomes an Incremental Bank under the Credit Agreement having the Incremental Term Loan set forth under such Bank’s name in Schedule 1 hereto (the “Incremental Term Loans”), effective as of the date hereof and agrees to be bound by the provisions of the Credit Agreement. Each Incremental Bank, severally and not jointly, agrees to make the Incremental Term Loans in dollars to the Company on the Increase Effective Date, in an aggregate amount not to exceed the amount of such Bank’s First Incremental Commitment. Notwithstanding anything to the contrary in the Credit Agreement, the Incremental Term Loans will share the same Interest Periods and will accrue interest at the same interest rate as the Initial Term Loans. The Incremental Loans and Incremental Commitments shall be entitled to all the benefits afforded by the Credit Agreement and the other Loan Papers and shall, without limiting the foregoing, benefit equally and ratably from the security interests created by the Loan Papers. The Incremental Term Loans will be secured by the Liens on the Collateral on a pari passu basis with the Initial Term Loans. 1.2 Representations and Warranties.

Section 2. Amendments to Existing Credit Agreement. 2.1 Replacement of Schedule II to Existing Credit Agreement.

The aggregate original amount of the Initial Commitments is $500,000,000.00. 2.3 Amended and Restated Definitions.

If and to the extent that any Bank shall not have made its ratable share of any Incremental Term Loan available to the Administrative Agent as assumed above, then such Bank and the Company severally agree to pay to the Administrative Agent, forthwith on demand, the amount of such Bank’s share so made available by the Administrative Agent, together with interest thereon, for each day from the date such amount was made available to the Company to the date such amount is paid to the Administrative Agent, at the Federal Funds Effective Rate. 2.5 Amendment to Section 9.

Solely in the event of a breach of any such terms which do not apply to a Restricted Bank by virtue of the foregoing sentence (but not with respect to any other breaches), the Loans and unused Commitments of any Restricted Bank shall be excluded in determining the Majority Banks with respect to waiving or consenting to matters relating to such breach.
