Organization, Consolidation and Presentation of Financial Statements [Abstract]
Summary of Significant Accounting Policies	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying unaudited Condensed Consolidated Financial Statements include the accounts of Delta Air Lines, Inc. and our consolidated subsidiaries and have been prepared in accordance with accounting principles generally accepted in the United States ("GAAP") for interim financial information. 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, 2021. 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 impacts from the COVID-19 pandemic and the ongoing recovery, seasonal variations in the demand for air travel, the volatility of aircraft fuel prices and other factors, operating results for the three and six months ended June 30, 2022 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. Recent Accounting Standards Standards Effective in Future Years Fair Value of Equity Investments. In 2022, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2022-03, "Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions." Under this standard, a contractual restriction on the sale of an equity security is not considered in measuring the security's fair value. The standard also requires certain disclosures for equity securities that are subject to contractual restrictions. The ASU becomes effective January 1, 2024, and we are evaluating the potential impact of this standard on our investments.

Revenue Recognition	REVENUE RECOGNITION Passenger Revenue Three Months Ended June 30, Six Months Ended June 30, (in millions) 2022 2021 2022 2021 Ticket $ 9,773 $ 4,553 $ 15,759 $ 6,830 Loyalty travel awards 744 428 1,287 669 Travel-related services 441 358 819 588 Total passenger revenue $ 10,958 $ 5,339 $ 17,865 $ 8,087 Ticket We recognized approximately $3.3 billion and $1.4 billion in passenger revenue during the six months ended June 30, 2022 and 2021, respectively, that had been recorded in our air traffic liability balance at the beginning of those periods. In order to provide our customers more flexibility and time to plan or rebook their travel, we announced in January 2022 that all existing travel credit holders will have until December 31, 2023 to rebook their ticket for travel throughout 2024. Additionally, all Delta customers with upcoming 2022 travel or who purchase a ticket in 2022 will also have the flexibility to rebook their ticket through December 31, 2023, and travel throughout 2024. The air traffic liability classified as current as of June 30, 2022 represents our estimate of tickets and travel credits to be used within one year. We will continue to monitor our customers' travel behavior and may adjust our estimates in the future. We estimate the value of tickets that will expire unused (“ticket breakage”) and recognize the related revenue at the scheduled flight date. Our ticket breakage estimates are primarily based on historical experience, ticket contract terms and customers’ travel behavior. Given the impact of the COVID-19 pandemic on customer behavior and changes made in ticket validity terms, as well as the elimination of change fees for most tickets, our estimates of revenue that will be recognized from the air traffic liability for unused tickets may vary in future periods. Loyalty Travel Awards Our SkyMiles loyalty program allows customers to earn mileage credits ("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 companies, hotels, car rental agencies and ridesharing 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 six months ended June 30, 2022 and 2021, total cash sales from marketing agreements related to our loyalty program were $2.6 billion and $1.8 billion, respectively, which are allocated to travel and other performance obligations. Loyalty travel awards revenue is related to the redemption of miles for air travel. 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. Loyalty program activity (in millions) 2022 2021 Balance at January 1 $ 7,559 $ 7,182 Miles earned 1,558 915 Miles redeemed for air travel (1,287) (669) Miles redeemed for non-air travel and other (73) (27) Balance at June 30 $ 7,757 $ 7,401 Travel-Related Services Travel-related services are primarily composed of services performed in conjunction with a passenger’s flight and include baggage fees, on-board sales and administrative fees.

This represents refinery sales to third parties, which are at or near cost; accordingly, the recorded margin on these sales is de minimis . Loyalty Program. This relates to brand usage by third parties and other performance obligations embedded in miles sold, including redemption of miles for non-air travel and other awards. These revenues are mainly included within the total cash sales from marketing agreements, discussed above. Ancillary Businesses. This represents revenues from aircraft maintenance services we provide to third parties and our vacation wholesale operations. Miscellaneous. This is primarily composed of revenues related to lounge access, including access provided to certain American Express cardholders, and codeshare agreements. 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: Passenger revenue by geographic region Passenger Revenue Three Months Ended June 30, Six Months Ended June 30, (in millions) 2022 2021 2022 2021 Domestic $ 8,318 $ 4,478 $ 13,881 $ 6,758 Atlantic 1,701 288 2,240 430 Latin America 745 485 1,425 749 Pacific 194 88 319 150 Total $ 10,958 $ 5,339 $ 17,865 $ 8,087 Operating revenue by geographic region Operating Revenue Three Months Ended June 30, Six Months Ended June 30, (in millions) 2022 2021 2022 2021 Domestic $ 10,655 $ 5,894 $ 18,204 $ 9,262 Atlantic 2,057 467 2,833 734 Latin America 854 586 1,665 967 Pacific 258 179 471 313 Total $ 13,824 $ 7,126 $ 23,173 $ 11,276

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, which 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. Restricted cash equivalents are recorded in prepaid expenses and other and other noncurrent assets 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. Short-Term Investments. Short-term investments consist of U.S. government and agency securities. The fair values of these investments are based on a market approach using industry standard valuation techniques that incorporate observable inputs such as quoted market prices, interest rates, benchmark curves, credit ratings of the security and other observable information. As of June 30, 2022, the estimated fair value of our short-term investments was $1.5 billion. Of these investments, $821 million are expected to mature in one year or less, with the remainder maturing by the first half of 2024. Investments with maturities beyond one year when purchased are classified as short-term investments if they are expected to be available to support our short-term liquidity needs. Long-Term Investments. 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 and forecasts provided by our investees. 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.

Investments, Debt and Equity Securities [Abstract]
Investments	INVESTMENTS We have developed strategic relationships with a number of airlines and airline services companies through joint ventures and other forms of cooperation and support, including equity investments. Our equity investments reinforce our commitment to these relationships and generally enhance our ability to offer input to the investee on strategic issues and direction, in some cases through representation on the board of directors. Fair Value Investments. Changes in the valuation of investments accounted for at fair value are recorded in gain/(loss) on investments, net in our income statement within non-operating expense and are driven by changes in stock prices, foreign currency fluctuations and other valuation techniques for investments in companies without publicly-traded shares. Equity Method Investments. We record our share of our equity method investees' financial results in our income statement as described in the table below. Equity investments ownership interest and carrying value Accounting Treatment Ownership Interest Carrying Value (in millions) June 30, 2022 December 31, 2021 June 30, 2022 December 31, 2021 Air France-KLM Fair Value 3 % 6 % $ 86 $ 165 China Eastern Fair Value 2 % 2 % 179 177 CLEAR Fair Value 6 % 6 % 166 260 Grupo Aeroméxico Equity Method (1) 20 % 51 % 420 — Hanjin-KAL Fair Value 13 % 13 % 419 455 Unifi Aviation Equity Method (2) 49 % 49 % 163 159 Wheels Up Fair Value (3) 21 % 21 % 101 241 Other investments Various 237 255 Equity investments $ 1,771 $ 1,712 (1) Results are included in equity method results in our income statement under non-operating expense. (2) Results are included in contracted services in our income statement as this entity is integral to the operations of our business by providing services at many of our airport locations. (3) We elected to account for our investment under the fair value option. Air France-KLM. During the June 2022 quarter, Air France-KLM ("AFKL") executed a €2.3 billion rights issue, through the issuance of 1.9 billion new AFKL shares. We participated in the rights issue on a cash neutral basis by subscribing to approximately 36 million new AFKL shares using the proceeds from the sale of part of our rights to a third party. The net impact of these transactions reduced our ownership interest to approximately 3% and the change in the fair value of our investment in AFKL is recorded in gain/(loss) on investments, net in our income statement within non-operating expense. Grupo Aeroméxico. In March 2022, Grupo Aeroméxico ("Aeroméxico") emerged from its voluntary proceedings to reorganize under Chapter 11 of the United States bankruptcy code ("bankruptcy process"). At the conclusion of the bankruptcy process, Aeroméxico's previously outstanding capital stock was consolidated and exchanged for less than 0.01% of new capital stock, which effectively eliminated our historical 51% ownership stake. Upon emergence, Delta received a 20% equity stake in the newly restructured Aeroméxico in exchange for (1) our receivables under Aeroméxico's debtor-in-possession financing, (2) $100 million (recorded as an investing outflow on our Condensed Consolidated Statements of Cash Flows), and (3) our agreement to provide expanded commercial services to Aeroméxico in future periods. We account for our investment in Aeroméxico under the equity method of accounting and record our share of Aeroméxico's financial results in equity method results in our income statement. Other Investments. This category includes various investments that are accounted for at fair value or under the equity method, depending on our ownership interest and the level of influence conveyed by our investment. Virgin Atlantic. Virgin Atlantic has completed an out-of-court restructuring, during which we provided and continue to provide strategic and operational assistance. The carrying value of our investment in Virgin Atlantic remains zero as of June 30, 2022. We maintained our 49% equity interest and continue to track our share of Virgin Atlantic's losses under the equity method of accounting, which are only recorded to the extent we make additional investments in Virgin Atlantic. LATAM. LATAM Airlines Group S.A. ("LATAM") is undergoing voluntary proceedings to reorganize under Chapter 11 of the United States bankruptcy code, and the carrying value of our investment in LATAM remains zero as of June 30, 2022. In order to support our relationship with LATAM, we are providing strategic and operational assistance through the bankruptcy process. After LATAM's refinancing in April 2022, we have a $71 million noncurrent receivable outstanding associated with LATAM's debtor-in-possession financing. LATAM's plan of reorganization has been confirmed by the Bankruptcy Court and is expected to take effect before the end of 2022. As our pre-bankruptcy equity ownership of approximately 20% will be substantially diluted to a de minimis

Availability Under Revolving Credit Facilities As of June 30, 2022, we had approximately $2.8 billion undrawn and available under our revolving credit facilities. In addition, we had outstanding letters of credit as of June 30, 2022, including approximately $100 million that reduced the availability under our revolving credit facilities and approximately $300 million that did not affect the availability of 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 2 within the fair value hierarchy. Fair value of outstanding debt (in millions) June 30, December 31, Net carrying amount $ 23,065 $ 25,084 Fair value $ 22,200 $ 26,900 Covenants Our debt agreements contain various affirmative, negative and financial covenants.

Deliveries of the pre-owned B-737-900ER aircraft are expected to occur by the end of 2022 and delivery of the A330-900 aircraft is expected to occur in 2024. Legal Contingencies We are involved in various legal proceedings related to employment practices, environmental issues, antitrust matters and other 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. Other Contingencies General Indemnifications We are the lessee under many commercial real estate leases. It is common in these transactions for us, as the lessee, to agree to indemnify the lessor and the lessor's related parties for tort, environmental and other liabilities that arise out of or relate to our use or occupancy of the leased premises. This type of indemnity would typically make us responsible to indemnified parties for liabilities arising out of the conduct of, among others, contractors, licensees and invitees at, or in connection with, the use or occupancy of the leased premises. This indemnity often extends to related liabilities arising from the negligence of the indemnified parties but usually excludes any liabilities caused by either their sole or gross negligence or their willful misconduct. Our aircraft and other equipment lease and financing agreements typically contain provisions requiring us, as the lessee or obligor, to indemnify the other parties to those agreements, including certain of those parties' related persons, against virtually any liabilities that might arise from the use or operation of the aircraft or other equipment. We believe that our insurance would cover most of our exposure to liabilities and related indemnities associated with the commercial real estate leases and aircraft and other equipment lease and financing agreements described above. While our insurance does not typically cover environmental liabilities, we have insurance policies in place as required by applicable environmental laws. Some of our aircraft and other financing transactions include provisions that require us to make payments to preserve an expected economic return to the lenders if that economic return is diminished due to specified changes in laws or regulations. In some of these financing transactions, we also bear the risk of changes in tax laws that would subject payments to non-U.S. lenders to withholding taxes. We cannot reasonably estimate our potential future payments under the indemnities and related provisions described above because we cannot predict (1) when and under what circumstances these provisions may be triggered and (2) the amount that would be payable if the provisions were triggered because the amounts would be based on facts and circumstances existing at such time. Other We have certain contracts for goods and services that require us to pay a penalty, acquire inventory specific to us or purchase contract-specific equipment, as defined by each respective contract, if we terminate the contract without cause prior to its expiration date. Because these obligations are contingent on our termination of the contract without cause prior to its expiration date, no obligation would exist unless such a termination occurs.

Segment Reporting [Abstract]
Segments	SEGMENTS Refinery Operations Our refinery segment operates for the benefit of the airline segment by providing jet fuel to the airline segment from its own production and through jet fuel obtained through agreements with third parties. The refinery's production consists of jet fuel, as well as non-jet fuel products. We use several counterparties to exchange the non-jet fuel products produced by the refinery for jet fuel consumed in our airline operations. The gross fair value of the products exchanged under these agreements during the three and six months ended June 30, 2022 was $1.0 billion and $1.8 billion, respectively, compared to $536 million and $1.0 billion for the three and six months ended June 30, 2021, respectively. Segment Reporting Segment results are prepared based on our internal accounting methods described below, with reconciliations to consolidated amounts in accordance with GAAP. Our segments are not designed to measure operating income or loss directly related to the products and services included in each segment on a stand-alone basis.

Fair Value Obligations The net fair value obligations presented in the financial information by segment for the three month periods table above are related to renewable fuel compliance costs, are presented net of any related assets or fixed price purchase agreements and are based on quoted market prices and other observable information and are therefore classified as Level 2 in the fair value hierarchy. Our obligation as of June 30, 2022 was calculated using the U.S. Environmental Protection Agency's ("EPA") Renewable Fuel Standard ("RFS") volume requirements, which were finalized in June 2022. The compliance deadlines to retire our obligations for 2020 and 2021 are in the fourth quarter of 2022 and first quarter of 2023, respectively.

Earnings/(Loss) Per Share	EARNINGS/(LOSS) PER SHARE We calculate basic earnings/(loss) per share and diluted loss per share by di viding net income/(loss) by the weighted average number of common shares outstanding, excluding restricted shares. We calculate diluted earnings per share by dividing net income by the weighted average number of common shares outstanding plus the dilutive effect of outstanding share-based instruments, including stock options, restricted stock awards and warrants. Ant idilutive common stock equivalents excluded from the diluted earnings per share calculation are not material.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited Condensed Consolidated Financial Statements include the accounts of Delta Air Lines, Inc. and our consolidated subsidiaries and have been prepared in accordance with accounting principles generally accepted in the United States ("GAAP") for interim financial information. 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, 2021. 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 impacts from the COVID-19 pandemic and the ongoing recovery, seasonal variations in the demand for air travel, the volatility of aircraft fuel prices and other factors, operating results for the three and six months ended June 30, 2022 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.
Recent Accounting Standards	Recent Accounting Standards Standards Effective in Future Years Fair Value of Equity Investments. In 2022, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2022-03, "Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions." Under this standard, a contractual restriction on the sale of an equity security is not considered in measuring the security's fair value. The standard also requires certain disclosures for equity securities that are subject to contractual restrictions. The ASU becomes effective January 1, 2024, and we are evaluating the potential impact of this standard on our investments.
Cash Equivalents and Restricted Cash Equivalents	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, which 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. Restricted cash equivalents are recorded in prepaid expenses and other and other noncurrent assets 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.
Short-Term and Long-Term Investments	Short-Term Investments. Short-term investments consist of U.S. government and agency securities. The fair values of these investments are based on a market approach using industry standard valuation techniques that incorporate observable inputs such as quoted market prices, interest rates, benchmark curves, credit ratings of the security and other observable information.
Fuel Hedge Contracts	Fuel Hedge Contracts. Our derivative contracts to hedge the financial risk from changing fuel prices are primarily related to inventory at our wholly-owned subsidiary, Monroe Energy, LLC ("Monroe"). Our fuel hedge portfolio may consist of a combination of options, swaps or futures contracts, most of which have a duration of less than three months. Option and swap contracts are valued under income approaches using option pricing models and discounted cash flow models, respectively, based on data either readily observable in public markets, derived from public markets or provided by counterparties who regularly trade in public markets. Futures contracts and options on futures contracts are traded on a public exchange and valued based on quoted market prices.
Fair Value Investments	Fair Value Investments. Changes in the valuation of investments accounted for at fair value are recorded in gain/(loss) on investments, net in our income statement within non-operating expense and are driven by changes in stock prices, foreign currency fluctuations and other valuation techniques for investments in companies without publicly-traded shares.
Equity Method Investments	Equity Method Investments. We record our share of our equity method investees' financial results in our income statement
