Consistent with these requirements, this Form 10-Q does not include all the information required by GAAP for complete financial statements. As a result, this Form 10-Q should be read in conjunction with the Consolidated Financial Statements and accompanying Notes in our Form 10-K for the year ended December 31, 2024. Management believes the accompanying unaudited Condensed Consolidated Financial Statements reflect all adjustments, including normal recurring items, considered necessary for a fair statement of results for the interim periods presented. Due to seasonal variations in the demand for air travel, the volatility of aircraft fuel prices and other factors, operating results for the three months ended March 31, 2025 are not necessarily indicative of operating results for the entire year. We reclassified certain prior period amounts to conform to the current period presentation. Unless otherwise noted, all amounts disclosed are stated before consideration of income taxes.

| REVENUE RECOGNITION | REVENUE RECOGNITION Passenger Revenue
Ticket We recognized approximately $4.1 billion and $3.9 billion in passenger revenue during the three months ended March 31, 2025 and 2024, respectively, that had been recorded in our air traffic liability balance at the beginning of those periods. Loyalty Travel Awards Loyalty travel awards revenue is related to the redemption of mileage credits ("miles") for air travel. Our SkyMiles loyalty program allows customers to earn miles by flying on Delta, Delta Connection and other airlines that participate in the loyalty program. Customers can also earn miles through participating companies, such as credit card, retail, ridesharing, car rental and hotel companies, who purchase miles from us. Our most significant contract to sell miles relates to our co-brand credit card relationship with American Express. During the three months ended March 31, 2025 and 2024, total cash sales from marketing agreements related to our loyalty program were $1.9 billion and $1.8 billion, respectively, which are allocated to travel and other performance obligations. Current Activity of the Loyalty Program. Miles are combined in one homogeneous pool and are not separately identifiable. Therefore, revenue is comprised of miles that were part of the loyalty program deferred revenue balance at the beginning of the period as well as miles that were issued during the period. The timing of mile redemptions can vary widely; however, the majority of miles have historically been redeemed within two years of being earned. The table below presents the activity of the current and noncurrent loyalty program deferred revenue and includes miles earned through travel and miles sold to participating companies, which are primarily through marketing agreements.
Travel-Related Services Travel-related services are primarily composed of services performed in conjunction with a passenger’s flight and include baggage fees, administrative fees and on-board sales. We recognize revenue for these services when the related transportation service is provided. Other Revenue
Revenue by Geographic Region Operating revenue for the airline segment is recognized in a specific geographic region based on the origin, flight path and destination of each flight segment. A significant portion of the refinery segment's revenues typically consists of fuel sales to support the airline, which is eliminated in the Condensed Consolidated Financial Statements. The remaining operating revenue for the refinery segment is included in the domestic region. Our passenger and operating revenue by geographic region is summarized in the following tables:

| FAIR VALUE MEASUREMENTS | FAIR VALUE MEASUREMENTS Assets/(Liabilities) Measured at Fair Value on a Recurring Basis
Cash Equivalents and Restricted Cash Equivalents. Cash equivalents generally consist of money market funds. Restricted cash equivalents generally consist of money market funds, time deposits, commercial paper and negotiable certificates of deposit. Restricted cash equivalents primarily relate to proceeds from debt issued to finance, among other things, a portion of the construction costs for our new terminal facilities at New York's LaGuardia Airport as well as certain self-insurance obligations and airport commitments. Restricted cash equivalents are recorded in other noncurrent assets and prepaid expenses and other on our Consolidated Balance Sheet ("balance sheet"). The fair value of these cash equivalents is based on a market approach using prices generated by market transactions involving identical or comparable assets. Long-Term Investments and Related. Our long-term investments measured at fair value primarily consist of equity investments, which are valued based on market prices or other observable transactions and inputs, and are recorded in equity investments on our balance sheet. Our equity investments in private companies are classified as Level 3 in the fair value hierarchy as their equity is not traded on a public exchange and our valuations incorporate certain unobservable inputs, including non-public equity issuances. Fair value measurement using unobservable inputs is inherently uncertain, and a change in significant inputs could result in different fair values. See Note 4, "Investments," for further information on our equity investments. Fuel Hedge Contracts. Our derivative contracts to hedge the financial risk from changing fuel prices are related to inventory at our wholly-owned subsidiary, Monroe Energy, LLC ("Monroe"). We recognized losses of $20 million on our fuel hedge contracts in aircraft fuel and related taxes on our Condensed Consolidated Statements of Operations and Comprehensive Income ("income statement") for the three months ended March 31, 2025, compared to losses of $96 million for the three months ended March 31, 2024. The losses recognized during the first three months of 2025 were composed of $22 million of mark-to-market losses and $2 million of settlement gains on contracts. Gains and losses on settled contracts are reflected within Monroe's operating results. See Note 9, "Segments," for further information on our refinery segment.

Availability Under Revolving Credit Facilities As of March 31, 2025, we had approximately $3.1 billion undrawn and available under our revolving credit facilities. Fair Value of Debt Market risk associated with our fixed- and variable-rate debt relates to the potential reduction in fair value and negative impact to future earnings, respectively, from an increase in interest rates. The fair value of debt shown below is principally based on reported market values, recently completed market transactions and estimates based on interest rates, maturities, credit risk and underlying collateral. Debt is primarily classified as Level 1 or 2 within the fair value hierarchy.
Covenants Our debt agreements contain various affirmative, negative and financial covenants. We were in compliance with the covenants in our debt agreements at March 31, 2025.

(1)The timing of these commitments is based on our contractual agreements with the aircraft manufacturers and remains uncertain due to supply chain, manufacturing and regulatory constraints. During the March 2025 quarter, Delta was notified that certain aircraft deliveries would be delayed from 2026 to 2027. These new delivery dates are reflected in the table above. Our future aircraft purchase commitments included the following aircraft at March 31, 2025:
Legal Contingencies We are involved in various legal proceedings related to employment practices, environmental issues, commercial disputes, antitrust and other regulatory matters concerning our business. We record liabilities for losses from legal proceedings when we determine that it is probable that the outcome in a legal proceeding will be unfavorable and the amount of loss can be reasonably estimated. Although the outcome of the legal proceedings in which we are involved cannot be predicted with certainty, we believe that the resolution of current matters will not have a material adverse effect on our Condensed Consolidated Financial Statements.
