COMBINED NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)	COMBINED NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) United Airlines Holdings, Inc. (together with its consolidated subsidiaries, "UAL" or the "Company") is a holding company and its wholly-owned subsidiary is United Airlines, Inc. (together with its consolidated subsidiaries, "United"). This Quarterly Report on Form 10-Q is a combined report of UAL and United, including their respective consolidated financial statements. As UAL consolidates United for financial statement purposes, disclosures that relate to activities of United also apply to UAL, unless otherwise noted. United's operating revenues and operating expenses comprise nearly 100% of UAL's revenues and operating expenses. In addition, United comprises approximately the entire balance of UAL's assets, liabilities and operating cash flows. When appropriate, UAL and United are named specifically for their individual contractual obligations and related disclosures, and any significant differences between the operations and results of UAL and United are separately disclosed and explained. We sometimes use the words "we," "our," "us," and the "Company" in this report for disclosures that relate to all of UAL and United. The UAL and United unaudited condensed consolidated financial statements shown here have been prepared as required by the U.S. Securities and Exchange Commission (the "SEC"). Some information and footnote disclosures normally included in financial statements that comply with accounting principles generally accepted in the United States ("GAAP") have been condensed or omitted as permitted by the SEC. The financial statements include all adjustments, including normal recurring adjustments and other adjustments, which are considered necessary for a fair presentation of the Company's financial position and results of operations for interim periods presented. The UAL and United financial statements should be read together with the information included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2022 (the "2022 Form 10-K"). The Company's quarterly financial data is subject to seasonal fluctuations. Historically its second and third quarter financial results have reflected higher travel demand, and were better than its first and fourth quarter financial results.

Revenue from Contract with Customer [Abstract]
REVENUE	REVENUE Revenue by Geography. The table below presents the Company's operating revenue by principal geographic region (as defined by the U.S. Department of Transportation) (in millions): Three Months Ended March 31, 2023 2022 Domestic (U.S. and Canada) $ 7,167 $ 5,086 Atlantic (including Europe, Africa, India and Middle East destinations) 1,832 1,089 Latin America 1,316 909 Pacific 1,114 482 Total $ 11,429 $ 7,566 Advance Ticket Sales. The Company defers amounts related to future travel in its Advance ticket sales liability account. All tickets sold at any given point in time have travel dates through the next 12 months. The Company's Advance ticket sales liability also includes credits issued to customers for future flights ("FFCs") and electronic travel certificates ("ETCs"), primarily for ticket cancellations, which can be applied towards a purchase of a new ticket. FFCs and ETCs are valid up to one year from the date of issuance; however, all credits issued on or before December 31, 2022 have been extended to December 31, 2023. The Company estimates the value of Advance tickets sales that will expire unused ("breakage") and recognizes revenue in proportion to the usage of the related tickets. To determine breakage, the Company uses its historical experience with expired tickets and certificates and other facts, such as recent aging trends, program changes and modifications that could affect the ultimate expiration patterns. Changes in our estimates of FFCs and ETCs that may expire unused could have a material impact on revenue. Changes in estimates of breakage are recognized prospectively in proportion to the remaining usage of the related tickets. In the three months ended March 31, 2023 and 2022, the Company recognized approximately $3.5 billion and $1.9 billion, respectively, of passenger revenue for tickets that were included in Advance ticket sales at the beginning of those periods. Ancillary Fees. The Company charges fees, separately from ticket sales, for certain ancillary services that are directly related to passengers' travel, such as baggage fees, premium seat fees, inflight amenity fees and other ticket-related fees. These ancillary fees are part of the travel performance obligation and, as such, are recognized as passenger revenue when the travel occurs. The Company recorded $892 million and $661 million of ancillary fees within passenger revenue in the three months ended March 31, 2023 and 2022, respectively. Frequent Flyer Accounting. The table below presents a roll forward of Frequent flyer deferred revenue (in millions): Three Months Ended March 31, 2023 2022 Total Frequent flyer deferred revenue - beginning balance $ 6,675 $ 6,282 Total miles awarded 747 477 Travel miles redeemed (531) (322) Non-travel miles redeemed (31) (20) Total Frequent flyer deferred revenue - ending balance $ 6,860 $ 6,417 In the three months ended March 31, 2023 and 2022, the Company recognized, in Other operating revenue, $646 million and $519 million, respectively, related to the marketing, advertising, non-travel miles redeemed (net of related costs) and other travel-related benefits of the mileage revenue associated with our various partner agreements including, but not limited to, our JPMorgan Chase Bank, N.A. MileagePlus co-brand agreement. The portion related to the MileagePlus miles awarded of the total amounts received from our various partner agreements is deferred and presented in the table above as an increase to the Frequent flyer deferred revenue. We determine the current portion of that account based on expected redemptions in the next 12 months.

(b) Represent warrants issued to the U.S. Treasury Department ("Treasury") pursuant to the payroll support program, including extensions, and the loan program established under the Coronavirus Aid, Relief, and Economic Security Act. The Company issued, to Treasury, warrants to purchase up to approximately 10 million shares of UAL common stock at exercise prices ranging from $31.50 to $53.92 and expiration dates ranging from April 20, 2025 to June 10, 2026. All warrants were outstanding as of March 31, 2023. On March 3, 2021, the Company entered into an equity distribution agreement (the "Distribution Agreement") with several financial institutions (collectively, the "Managers"), relating to the issuance and sale from time to time by UAL (the "2021 ATM Offering"), through the Managers, of up to 37 million shares of UAL common stock (the "2021 ATM Shares"). Sales of the 2021 ATM Shares under the Distribution Agreement were allowed to be made in any transactions that were deemed to be "at the market offerings" as defined in Rule 415 under the Securities Act of 1933, as amended. During 2021, approximately 4 million shares were sold in the 2021 ATM Offering at an average price of $57.50 per share, with net proceeds to the Company totaling approximately $250 million. No shares were sold in 2022 or 2023 under the 2021 ATM Offering, which expired in March 2023.

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXESThe Company's effective tax rates for the three months ended March 31, 2023 and March 31, 2022 were 24.2% and 21.4%, respectively. The provision for income taxes for the three months ended March 31, 2023 is based on the estimated annual effective tax rate, which represents a blend of federal, state and foreign taxes and includes the impact of certain nondeductible items. The provision for income taxes for the three months ended March 31, 2022 is calculated using a discrete effective tax rate method. We determined that applying an estimate of the annual effective tax rate to income or loss for the interim reporting period would not provide a reliable estimate for the three months ended March 31, 2022, since small changes in estimated income would have resulted in significant changes in the estimated annual effective tax rate.

Equity Method Investments. As of March 31, 2023, United holds the following investments, accounted for using the equity method, with a combined carrying value of approximately $208 million: • CommuteAir LLC. United owns a 40% minority ownership stake in CommuteAir LLC. CommuteAir currently operates 61 regional aircraft under a capacity purchase agreement ("CPA") that has a term through 2026. • Republic Airways Holdings Inc. United holds a 19% minority interest in Republic Holdings Inc., which is the parent company of Republic Airways Inc. ("Republic"). Republic currently operates 66 regional aircraft under CPAs that have terms through 2036. • United Airlines Ventures Sustainable Flight Fund (the "Fund"). During the first quarter of 2023, United launched, through its corporate venture capital arm, United Airlines Ventures ("UAV"), an investment vehicle designed to support start-ups focused on decarbonizing air travel by accelerating the research, production and technologies associated with sustainable aviation fuel ("SAF"). The Fund started with more than $100 million in commitments from United and other corporate investors, collectively, as limited partners. UAV transferred certain of its existing SAF investments to the Fund's portfolio. As of March 31, 2023, the Company indirectly holds a 49.99% ownership interest in the Fund. • Blue Blade Energy, LLC ("Blue Blade"). UAV holds a 20% minority interest in Blue Blade, a joint venture with Tallgrass Energy Partners, LP, and Green Plains Inc. to develop and then commercialize a novel SAF technology that uses ethanol as its feedstock. Other Investments. As of March 31, 2023, United has equity investments in Avianca Group International Limited, a multinational airline holding company, JetSuiteX, Inc., an independent air carrier doing business as JSX as well as a number of companies with emerging technologies and sustainable solutions. None of these investments have readily determinable fair values. We account for these investments at cost less impairment, adjusted for observable price changes in orderly transactions for an identical or similar investment of the same issuer. As of March 31, 2023, the carrying value of these investments was $413 million.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Commitments. As of March 31, 2023, United had firm commitments and options to purchase aircraft from The Boeing Company ("Boeing") and Airbus S.A.S. ("Airbus") as presented in the table below: Scheduled Aircraft Deliveries Aircraft Type Number of Firm Last Nine Months 2024 After 2024 787 100 — 8 92 737 MAX 412 114 88 210 A321neo 70 12 31 27 A321XLR 50 — — 50 A350 45 — — 45 (a) United also has options and purchase rights for additional aircraft. The aircraft listed in the table above are scheduled for delivery through 2033. The amount and timing of the Company's future capital commitments could change to the extent that: (i) the Company and the aircraft manufacturers, with whom the Company has existing orders for new aircraft, agree to modify the contracts governing those orders; (ii) rights are exercised pursuant to the relevant agreements to modify the timing of deliveries; or (iii) the aircraft manufacturers are unable to deliver in accordance with the terms of those orders. Airbus notified United that eight Airbus A321neo aircraft scheduled for delivery in 2023, as shown in the table above, are now expected to deliver in 2024 and ten Airbus A321neo aircraft scheduled for delivery in 2024, as shown in the table above, are now expected to deliver in 2025. Boeing notified United that 37 Boeing 737 MAX aircraft scheduled for delivery in 2023, as shown in the table above, are now expected to deliver in 2024. Also, United estimates that an additional eleven Boeing 737 MAX aircraft scheduled for delivery in 2023, as shown in the table above, will deliver in 2024 and 30 Boeing 737 MAX aircraft scheduled for delivery in 2024, as shown in table above, will deliver in 2025. Furthermore, Boeing recently notified United that due to a manufacturing process issue relating to certain Boeing 737 MAX fuselages, six Boeing 737 MAX 8 aircraft scheduled for delivery in the second quarter of 2023, as shown in the table above, will be delayed. Boeing may inform United that additional Boeing 737 MAX 8 aircraft scheduled for delivery in the third quarter of 2023 may be delayed and/or that certain Boeing 737 MAX aircraft currently expected to be delivered in 2023 may deliver in 2024. However, at this time, we do not expect these delays to be extensive or to have a significant impact on our capacity plan for 2023. During the first quarter of 2023, United entered into agreements with third parties to finance through sale and leaseback transactions new Boeing model 737 MAX aircraft subject to purchase agreements between United and Boeing. For certain aircraft, United assigned its right to purchase such aircraft to the buyer, and simultaneous with the buyer's purchase from Boeing, United entered into a long-term lease for such aircraft with the buyer as lessor. Upon delivery of the aircraft in these sale and leaseback transactions, the Company accounted for these aircraft as part of Flight equipment on the Company's consolidated balance sheet and the related obligation recorded in Current maturities of other financial liabilities and Other financial liabilities since they did not qualify for sale recognition (failed sale and leaseback). The table below summarizes United's commitments as of March 31, 2023, which include aircraft and related spare engines, aircraft improvements and non-aircraft capital commitments. Aircraft commitments are based on contractual scheduled aircraft deliveries without any adjustments for the delays communicated by Boeing and Airbus or estimated by United. (in billions) Last nine months of 2023 $ 8.3 2024 8.1 2025 8.3 2026 5.9 2027 4.7 After 2027 16.8 $ 52.1 Regional CPAs . In the first quarter of 2023, United amended its CPA agreements with one of its regional carriers to increase the contractually agreed fees (carrier costs) paid to that carrier. The Company expects to wind down its CPA with Air Wisconsin and terminate operations by early June 2023. Our future commitments under our CPAs are dependent on numerous variables, and are, therefore, difficult to predict. The most important of these variables is the number of scheduled block hours. Although we are not required to purchase a minimum number of block hours under certain of our CPAs, we have set forth below estimates of our future payments under the CPAs based on our assumptions. The actual amounts we pay to our regional operators under CPAs could differ materially from these estimates. United's estimates of its future payments under all of the CPAs do not include the portion of the underlying obligation for any aircraft leased to a regional carrier or deemed to be leased from other regional carriers and facility rent that are disclosed as part of operating leases above. For purposes of calculating these estimates, we have assumed (1) the number of block hours flown is based on our anticipated level of flight activity or at any contractual minimum utilization levels if applicable, whichever is higher, (2) that we will reduce the fleet as rapidly as contractually allowed under each CPA, (3) that aircraft utilization, stage length and load factors will remain constant, (4) that each carrier's operational performance will remain at recent historic levels and (5) an annual projected inflation rate. Based on these assumptions as of March 31, 2023 , our estimated future payments through the end of the terms of our CPAs are presented in the table below : (in billions) Last nine months of 2023 $ 1.7 2024 2.1 2025 1.8 2026 1.6 2027 1.1 After 2027 3.9 $ 12.2 Guarantees. As of March 31, 2023, United is the guarantor of approximately $2.0 billion in aggregate principal amount of tax-exempt special facilities revenue bonds and interest thereon. These bonds, issued by various airport municipalities, are payable solely from rentals paid under long-term agreements with the respective governing bodies. The leasing arrangements associated with these obligations are accounted for as operating leases recognized on the Company's consolidated balance sheet with the associated expense recorded on a straight-line basis over the expected lease term. All of these bonds are due between 2023 and 2041. As of March 31, 2023, United is the guarantor of $88 million of aircraft mortgage debt issued by one of United's regional carriers. The aircraft mortgage debt is subject to similar increased cost provisions as described below for the Company's debt, and the Company would potentially be responsible for those costs under the guarantees. Increased Cost Provisions. In United's financing transactions that include loans in which United is the borrower, United typically agrees to reimburse lenders for any reduced returns with respect to the loans due to any change in capital requirements and, in the case of loans with respect to which the interest rate is based on the London Interbank Offered Rate (LIBOR) or the Secured Overnight Financing Rate (SOFR), for certain other increased costs that the lenders incur in carrying these loans as a result of any change in law, subject, in most cases, to obligations of the lenders to take certain limited steps to mitigate the requirement for, or the amount of, such increased costs. At March 31, 2023, the Company had $12.9 billion of floating rate debt with remaining terms of up to approximately 12 years that are subject to these increased cost provisions. In several financing transactions involving loans or leases from non-U.S. entities, with remaining terms of up to approximately 12 years and an aggregate balance of $9.7 billion, the Company bears the risk of any change in tax laws that would subject loan or lease payments thereunder to non-U.S. entities to withholding taxes, subject to customary exclusions. Labor . As of March 31, 2023, the Company had approximately 96,300 employees, of whom approximately 84% were represented by various U.S. labor organizations. In January 2023, United and the International Brotherhood of Teamsters ratified an extension to its labor contract covering the Company's more than 8,000 technicians and related employees. The agreement becomes amendable in December 2024 and includes a one-year early opener that allows for bargaining on a successor agreement to begin in December 2023. In April 2023, the Company and the International Association of Machinists & Aerospace Workers ("IAM") reached a tentative agreement covering nearly 30,000 IAM-represented employees in several workgroups. The agreements, once ratified, will cover IAM-represented employees across our operations and be effective through 2025. The Company has been in negotiations with its employees represented by the Air Line Pilots Association ("ALPA") regarding a contract that became amendable in January 2019. Given the recent ratification of a new agreement by the pilot group of another major airline, the Company has determined that it is appropriate to accrue expense in the first quarter 2023 related to a potential new collective bargaining agreement with employees represented by ALPA.
