Forward Looking Statements

Unless otherwise indicated or the context otherwise requires, the terms "Delta," "we," "us" and "our" refer to Delta Air Lines, Inc. and its subsidiaries.

FORWARD-LOOKING STATEMENTS

Statements in this Form 10-Q (or otherwise made by us or on our behalf) that are not historical facts, including statements about our estimates, expectations, beliefs, intentions, projections, goals, aspirations, commitments or strategies for the future, may be "forward-looking statements" as defined in the Private Securities Litigation Reform Act of 1995. Forward-looking statements involve risks and uncertainties that could cause actual results to differ materially from historical experience or our present expectations. Known material risk factors applicable to Delta are described in "Item 1A. Risk Factors" of our Annual Report on Form 10-K for the fiscal year ended December 31, 2021 ("Form 10-K"), other than risks that could apply to any issuer or offering. All forward-looking statements speak only as of the date made, and we undertake no obligation to publicly update or revise any forward-looking statements to reflect events or circumstances that may arise after the date of this report except as required by law.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of

Delta Air Lines, Inc.

Results of Review of Interim Financial Statements

We have reviewed the accompanying consolidated balance sheet of Delta Air Lines, Inc. (the Company) as of March 31, 2022, the related condensed consolidated statements of operations and comprehensive loss, condensed consolidated statements of cash flows, and consolidated statements of stockholders' equity for the three-month periods ended March 31, 2022 and 2021, and the related notes (collectively referred to as the "condensed consolidated interim financial statements"). Based on our reviews, we are not aware of any material modifications that should be made to the condensed consolidated interim financial statements for them to be in conformity with U.S. generally accepted accounting principles.

We have previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheet of the Company as of December 31, 2021, the related consolidated statements of operations, comprehensive income/(loss), cash flows, and stockholders' equity for the year then ended, and the related notes (not presented herein); and in our report dated February 11, 2022, we expressed an unqualified audit opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying consolidated balance sheet as of December 31, 2021, is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived.

Basis for Review Results

These financial statements are the responsibility of the Company's management. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the SEC and the PCAOB. We conducted our review in accordance with the standards of the PCAOB. A review of interim financial statements consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the PCAOB, the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

NOTE 1. 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 months ended March 31, 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.

NOTE 2. REVENUE RECOGNITION

Passenger Revenue

Three Months Ended March 31,
(in millions)20222021
Ticket$5,986$2,277
Loyalty travel awards543241
Travel-related services378230
Total passenger revenue$6,907$2,748

Ticket

We recognized approximately $2.2 billion and $822 million in passenger revenue during the three months ended March 31, 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, in January 2022, we announced 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 March 31, 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.

Notes to the Consolidated Financial Statements

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 three months ended March 31, 2022 and 2021, total cash sales from marketing agreements related to our loyalty program were $1.2 billion and $767 million, 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.

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.

Refinery. This represents refinery sales to third parties, which are at or near cost; accordingly, the margin on these sales is de minimis.

Loyalty Program. Loyalty program revenues relate 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. Ancillary businesses includes aircraft maintenance services we provide to third parties and our vacation wholesale operations.

Miscellaneous. Miscellaneous revenue is primarily composed of lounge access, including access provided to certain American Express cardholders, and codeshare revenues.

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:

Cash Equivalents and Restricted Cash Equivalents. Cash equivalents generally consist of money market funds. Restricted cash equivalents are recorded in prepaid expenses and other and other noncurrent assets on our Consolidated Balance Sheet ("balance sheet"). 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. 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 March 31, 2022, the estimated fair value of our short-term investments was $2.2 billion. Of these investments, $1.6 billion are expected to mature in one year or less, with the remainder maturing during 2023. 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.

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. 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. We recognized losses of $240 million and $57 million on our fuel hedge contracts in aircraft fuel and related taxes on our Condensed Consolidated Statements of Operations and Comprehensive Loss ("income statement") for three months ended March 31, 2022 and 2021, respectively. The losses recognized during the March 2022 quarter are composed of $244 million of settlements on contracts and $4 million of mark-to-market adjustments. Expense from the settlement of closed contracts is offset by higher operating profits at Monroe from higher pricing. See Note 9, "Segments," for further information on our Monroe refinery segment.

Notes to the Consolidated Financial Statements

NOTE 4. 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.

(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 our airport locations.

(3)We account for our investment under the fair value option.

Grupo Aeroméxico. On March 17, 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 ("cash flows statement")), and (3) our agreement to provide expanded commercial services to Aeroméxico in future periods. We will 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 March 31, 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 March 31, 2022. In order to support our relationship with LATAM, we are providing strategic and operational assistance through the bankruptcy process. We have a $175 million noncurrent receivable outstanding associated with LATAM's debtor-in-possession financing. Upon completion of its bankruptcy process, we expect to receive an approximately 10% equity stake in LATAM in exchange for an additional investment in LATAM.

Notes to the Consolidated Financial Statements

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.

NOTE 9. 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 months ended March 31, 2022 and 2021 was $809 million and $503 million, 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 table above are related to renewable fuel compliance costs 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 March 31, 2022 was calculated using the U.S. Environmental Protection Agency's ("EPA") proposed Renewable Fuel Standard ("RFS") volume requirements, which were issued in December 2021. The EPA has not finalized the compliance deadlines to retire our obligations for 2020 and 2021, but we expect those deadlines to be within one year of the effective date of the new RFS volume requirements.

NOTE 10. LOSS PER SHARE

We calculate basic loss per share and diluted loss per share by dividing net loss by the weighted average number of common shares outstanding, excluding restricted shares. Antidilutive common stock equivalents excluded from the diluted loss per share calculation are not material. The following table shows the computation of basic and diluted loss per share:

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our Condensed Consolidated Financial Statements and the related notes and other financial information included elsewhere in this Quarterly Report on Form 10-Q and our audited consolidated financial statements and related notes included in our 2021 Form 10-K.

March 2022 Quarter Financial Overview

Our business and operating results continued to be impacted by the COVID-19 pandemic in the March 2022 quarter. We have seen continued improvement in our business during the March 2022 quarter, which we expect to continue throughout 2022. Given the drastic and unprecedented impact of the COVID-19 pandemic on our operating results in 2021 and 2020, we believe that a comparison of our results in the March 2022 quarter to both the March 2021 and March 2019 quarters in this overview section allows for a better understanding of the full impact of the COVID-19 pandemic and the progress of our recovery.

The table below shows selected key financial and statistical measures for the three months ended March 31, 2022, 2021 and 2019.

Three Months Ended March 31,2022 vs. 2021 % Increase (Decrease) (1)2022 vs. 2019 % Increase (Decrease) (1)

**(1)**Certain variances are labeled as not meaningful ("NM") throughout management's discussion and analysis.

Our operating loss for the March 2022 quarter was $783 million, an improvement of $615 million compared to the March 2021 quarter. This improvement was primarily due to a $4.2 billion, or 151%, increase in passenger revenue as a result of increased demand and capacity, partially offset by a $1.1 billion increase in fuel expense, $1.2 billion of Payroll Support Programs ("PSP") grant proceeds recognized during the March 2021 quarter and increases in other volume related expenses as we continue to restore our operation.

Compared to operating income of $1.0 billion in the March 2019 quarter, our operating loss primarily resulted from the continued impact of the COVID-19 pandemic on our business which led to a 25% decrease in passenger revenue.

Revenue. Compared to the March 2021 quarter, our operating revenue increased $5.2 billion, or 125%, due primarily to increased travel demand and higher refinery third party sales.

Compared to the March 2019 quarter, our operating revenue was $1.1 billion lower, or 11%, on 17% lower system capacity, due primarily to the continued impact of the COVID-19 pandemic on travel demand, partially offset by higher refinery third party sales. We expect system capacity to be approximately 85% recovered in the June 2022 quarter compared to the June 2019 quarter. We have the ability to return to 2019 capacity levels by the end of 2022, if demand warrants.

Beginning in the latter half of the March 2021 quarter, we began to see bookings, primarily among domestic consumers, improve from the low levels of 2020. Throughout 2021, demand continued to improve, with some variability in periods of rising COVID-19 cases attributable to variants of the virus. Consumer demand accelerated through the March 2022 quarter, highlighted by strong spring break performance. As the omicron variant faded, offices reopened and travel restrictions were lifted, leading to improved demand for business travel and a strengthened fare environment. The sale of tickets to domestic business customers (i.e., both corporate and contracted small- and medium-sized enterprises), including tickets for travel during and beyond the quarter (“domestic corporate advance sales”), significantly improved during the March 2022 quarter. We remain optimistic about the ultimate recovery of business travel; however, we are unable to fully predict the pace of that recovery.

Delta Air Lines, Inc. March 2022 Form 10-Q 18

Item 2. MD&A

International revenue continues to lag the recovery in domestic travel due to certain international testing requirements and travel restrictions, but improved in the March 2022 quarter to approximately 55% recovered compared to the March 2019 quarter. During the March 2022 quarter, many European countries removed entry testing requirements for vaccinated travelers. The sale of tickets to international business customers (i.e., both corporate and contracted small- and medium-sized enterprises), including tickets for travel during and beyond the quarter (“international corporate advance sales”), significantly improved during the March 2022 quarter. Despite the recent policy changes and improved advance sales, we expect the lower international revenue environment to continue through at least the second quarter of 2022, with the recovery of international revenue continuing to trail domestic revenue.

Operating Expense. Total operating expense in the March 2022 quarter increased $4.6 billion, or 83%, compared to the March 2021 quarter, primarily resulting from increased fuel costs due to both an increase in fuel price and increased capacity and higher volume-related expenses associated with the increase in capacity and demand, mainly aircraft maintenance and higher salaries and related costs. The increase also resulted from $1.2 billion of PSP grant proceeds recognized during the March 2021 quarter, which reduced expenses and an increase in expenses related to refinery sales to third parties, reflected in ancillary business and refinery expense. Total operating expense, adjusted (a non-GAAP financial measure) for the March 2022 quarter increased $2.7 billion, or 43%, compared to the March 2021 quarter. Adjustments were primarily to exclude expenses related to refinery sales to third parties and PSP grant proceeds in the March 2021 quarter.

Total operating expense in the March 2022 quarter increased $679 million, or 7%, compared to the March 2019 quarter, primarily resulting from increased expenses related to refinery sales to third parties, reflected in ancillary business and refinery expense. Total operating expense, adjusted (a non-GAAP financial measure) for the March 2022 quarter decreased $400 million, or 4%, compared to the March 2019 quarter. Adjustments were primarily to exclude expenses related to refinery sales to third parties.

Cash Flow. Our cash, cash equivalents, short-term investments and aggregate principal amount committed and available to be drawn under our revolving credit facilities ("liquidity") as of March 31, 2022 was $12.8 billion. During the March 2022 quarter, operating activities generated $1.8 billion.

During the March 2022 quarter, the air traffic liability increased approximately $2.8 billion. We sell tickets for air travel in advance of the customer's travel date and the cash received on these advance sales is recorded as deferred revenue in our air traffic liability. Passenger revenue is recognized and the air traffic liability is reduced when we provide transportation services. The increase in the air traffic liability exceeds our historical seasonal increase, reflecting the continued restoration of our business.

As discussed above, consumer demand for travel accelerated through the quarter. Domestic corporate advance sales for the March 2022 quarter were approximately 50% recovered compared to the March 2019 quarter and the month of March was approximately 70% recovered versus 2019. The domestic corporate advance sales recovery was also nearly 40 percentage points higher in the March 2022 quarter compared to the March 2021 quarter. International corporate advance sales for the March 2022 quarter were approximately 35% recovered compared to the March 2019 quarter, with the month of March improving to approximately 50% compared to March 2019. Internationally, Transatlantic improved the most as European countries reopened. The international corporate advance sales recovery was also nearly 30 percentage points higher in the March 2022 quarter compared to the March 2021 quarter.

Additionally, total cash sales to American Express were $1.2 billion in the March 2022 quarter up 25% compared to the March 2019 quarter.

Also during the quarter, investing activities used a net of $749 million, primarily for capital expenditures, partially offset by net redemptions of short-term investments. These activities resulted in $197 million of free cash flow (a non-GAAP financial measure) in the March 2022 quarter. Also, during the March 2022 quarter we had cash outflows of approximately $1.4 billion related to repayments of our debt and finance leases.

The non-GAAP financial measures referenced above for operating expense, adjusted and free cash flow are defined and reconciled in "Supplemental Information" below.

Environmental Sustainability. During 2022, we are continuing to develop our climate transition plan and to have our medium- and long-term climate goals, including our goal of achieving net zero greenhouse gas emissions no later than 2050, validated by the Science Based Targets initiative, as described in our 2021 Form 10-K. We expect our path toward achievement of these goals to depend heavily on increased use of sustainable aviation fuel ("SAF") which is not presently available at scale or at prices competitive to jet fuel, and improved fuel efficiency from fleet renewal and operational initiatives. In the three months ended March 31, 2022, we also incurred $47 million of expense related to carbon offset credits, which relates to a portion of our airline segment's 2021 carbon emissions.

Operating Revenue

Compared to the March 2021 quarter, our operating revenue increased $5.2 billion, or 125%, due to the continued recovery in demand from the COVID-19 pandemic and higher refinery third party sales. The increase in operating revenue, on a 29% increase in capacity, resulted in a 74% increase in total revenue per available seat mile ("TRASM") and a 75% increase in TRASM, adjusted compared to the March 2021 quarter. The growth in passenger revenue was due to increased demand in both main cabin and premiums products, with premium products experiencing a quicker recovery than main cabin.

See "Refinery Segment" below for additional details on the refinery's operations, including third party refinery sales recorded in other revenue.

We have historically generated cargo revenues in domestic and international markets through the use of cargo space on regularly scheduled passenger aircraft. In 2020 and 2021, following the onset of the COVID-19 pandemic, reduced industry cargo capacity drove a significant increase in our cargo yield, and we also generated cargo revenue through the operation of cargo-only charter flights (i.e., using aircraft in our fleet not being utilized for passenger travel to fly cargo internationally). The higher cargo yield trend has continued into the March 2022 quarter driving the increase in revenue compared to the March 2021 quarter. We expect capacity constraints and elevated market yields to continue through 2022 while the industry rebuilds international networks to pre-pandemic levels.

Domestic

Domestic passenger unit revenue ("PRASM") increased in the March 2022 quarter compared to the March 2021 quarter as a result of the higher levels of capacity and demand during the March 2022 quarter due to the ongoing recovery in the period.

Delta Air Lines, Inc. March 2022 Form 10-Q 21

Item 2. MD&A - Results of Operations

The March 2022 quarter domestic consumer revenue was above March 2021 quarter levels. After starting with somewhat muted demand recovery due to rising COVID-19 cases attributable to variants of the virus, revenue recovery accelerated during the quarter as consumers continued to show increased confidence in travel.

We also remain optimistic about the ultimate recovery of business travel, which is comprised of both corporate managed travel and small- and medium-sized businesses, and expect the recovery of both of these components to continue to increase throughout 2022. Business travel demand in the March 2022 quarter was the highest since the onset of the COVID-19 pandemic.

International

International passenger revenue for the March 2022 quarter increased compared to the March 2021 quarter as travel to certain destinations has resumed or increased. While some countries have removed or eased travel restrictions, many countries still maintain international testing requirements and travel restrictions, which have restrained demand in the short-term.

In November 2021, travel restrictions for fully vaccinated foreign visitors to the United States were lifted. This action made travel to the U.S. by many foreign nationals possible for the first time in 18 months. Despite this policy change, we expect the lower international revenue environment to continue through at least the second quarter of 2022, with the recovery of international revenue continuing to trail domestic revenue. We will continue to be nimble in the restoration of our international network based on changes in government restrictions and consumer demand.

The Atlantic region continues to improve, despite the conflict in Ukraine, as western European countries remove or ease travel restrictions. In February 2022, we suspended our codeshare services operated in conjunction with Russian national airline, Aeroflot, which is not expected to have a material impact on our Atlantic region revenues as Russia and Ukraine represent less than one percent of our Atlantic region traffic.

The Latin America region has shown the most recovery of the international regions, with continued demand improvement for leisure destinations in the Caribbean, Mexico and Central America. We expect this trend to continue throughout 2022 with the recovery in Latin America leading the Atlantic and Pacific regions.

The Pacific region continues to be the most impacted by the restrictions described above. Travel in the Pacific region remains largely limited to essential travel, and we expect only small demand improvements until government restrictions ease, such as South Korea's recent announcement that vaccinated travelers would be able to enter the country without quarantine beginning on April 1, 2022.

Ticket Validity Flexibility

In order to provide our customers more flexibility and time to plan or rebook their travel, in January 2022, we announced 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.

We estimate the value of 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.

Refinery. This represents refinery sales to third parties. These sales, which are at or near cost, increased $647 million compared to the March 2021 quarter. The increase in third-party refinery sales resulted from higher pricing and production during the March 2022 quarter compared to the March 2021 quarter. See "Refinery Segment" below for additional details on the refinery's operations, including third party refinery sales recorded in other revenue.

Loyalty Program. Loyalty program revenues relate to brand usage by third parties and other performance obligations embedded in miles sold, including redemption of miles for non-travel awards. These revenues are mainly driven by customer spend on American Express cards and new cardholder acquisitions. As co-brand card spend and card acquisitions continue to be strong, revenues from our relationship with American Express increased in the March 2022 quarter compared to 2021.

Ancillary Businesses. Ancillary businesses revenue includes aircraft maintenance services we provide to third parties and our vacation wholesale operations.

Miscellaneous. Miscellaneous revenue is primarily composed of lounge access, including access provided to certain American Express cardholders, and codeshare revenues. The volume of these transactions has increased compared to the March 2021 quarter due to the ongoing recovery of our business that continued to materialize in the March 2022 quarter. Our network of Delta Sky Club lounges was fully reopened by the end of July 2021 after some lounges temporarily closed at the onset of the pandemic in 2020.
