Debt Disclosure [Abstract]

DEBT

As of September 30, 2023, we had $1.75 billion undrawn and available under our revolving credit facility.

Our debt agreements contain customary terms and conditions as well as various affirmative, negative and financial covenants that, among other things, restrict the ability of the Company and its subsidiaries to incur additional indebtedness and pay dividends or repurchase stock. As of September 30, 2023, UAL and United were in compliance with their respective debt covenants.

Equipment Notes. On June 20, 2023, the Company and Wilmington Trust, National Association, as subordination agent and pass through trustee (the "Trustee") under a certain pass through trust newly formed by the Company, entered into the Note Purchase Agreement, dated as of June 20, 2023 (the "Note Purchase Agreement"). The Note Purchase Agreement provides for the issuance by the Company of equipment notes (the "Equipment Notes") in the aggregate principal amount of $1.3 billion to finance 39 Boeing aircraft delivered new to the Company from August 2022 to May 2023. Pursuant to the Note Purchase Agreement, the Trustee purchased Equipment Notes issued under a trust indenture and mortgage (each, an "Indenture" and, collectively, the "Indentures") with respect to each aircraft entered into by the Company and Wilmington Trust, National Association, as mortgagee. Each Indenture provides for the issuance of Equipment Notes in a single series, Series A, bearing interest at the rate of 5.80% per annum. The Equipment Notes were purchased by the Trustee, using the proceeds from the sale of Pass Through Certificates, Series 2023-1A, issued by a pass through trust newly-formed by the Company to facilitate the financing of the aircraft. The interest on the Equipment Notes is payable semi-annually on each January 15 and July 15, beginning on January 15, 2024. The principal payments on the Equipment Notes are scheduled on January 15 and July 15 of each year, beginning on July 15, 2024. The final payments on the Equipment Notes will be due on January 15, 2036.

In the second quarter of 2023, United prepaid $1.0 billion of a 2021 term loan facility. See Note 9 for information related to charges recorded as a result of this prepayment.

The table below presents the Company's contractual principal payments (not including $303 million of unamortized debt discount, premiums and debt issuance costs) at September 30, 2023 under then-outstanding long-term debt agreements (in millions):

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 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.

Fair value of the financial instruments included in the tables above was determined as follows:


Description			Fair Value Methodology
Cash and cash equivalents and Restricted cash (current and non-current)			The carrying amounts of these assets approximate fair value.
Short-term and Long-term investments			Fair value is based on (a) the trading prices of the investment or similar instruments or (b) broker quotes obtained by third-party valuation services.
Long-term debt			Fair values were based on either market prices or the discounted amount of future cash flows using our current incremental rate of borrowing for similar liabilities or assets.

Equity Method Investments. As of September 30, 2023, United holds the following investments, accounted for using the equity method, with a combined carrying value of approximately $232 million:

•CommuteAir LLC. United owns a 40% minority ownership stake in CommuteAir LLC. CommuteAir currently operates 53 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 Airways 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 September 30, 2023, the Company indirectly holds a 38% ownership interest in the Fund and the Fund has approximately $200 million in commitments from United and other corporate investors.

Other Investments. As of September 30, 2023, United has equity investments in Abra Group 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 September 30, 2023, the carrying value of these investments was $425 million.

Commitments and Contingencies Disclosure [Abstract]

COMMITMENTS AND CONTINGENCIES

Commitments. As of September 30, 2023, United had firm commitments to purchase aircraft from The Boeing Company ("Boeing") and Airbus S.A.S. ("Airbus") as presented in the table below:


		Contractual Aircraft Deliveries			Expected Aircraft Deliveries (b)
Aircraft Type	Number of Firm Commitments (a)	Last Three Months of 2023	2024	After 2024	Last Three Months of 2023	2024	After 2024
787	150	—	8	142	—	8	142
737 MAX	374	73	100	201	20	77	277
A321neo	130	4	26	100	4	26	100
A321XLR	50	—	—	50	—	—	50
A350	45	—	—	45	—	—	45
(a) United also has options and purchase rights for additional aircraft.
(b) Expected aircraft deliveries reflect adjustments communicated by Boeing and Airbus or estimated by United.

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 cancel deliveries or modify the timing of deliveries; or (iii) the aircraft manufacturers are unable to deliver in accordance with the terms of those orders.

On September 28, 2023, United entered into a supplemental agreement with Boeing, pursuant to which United exercised options to purchase 50 Boeing 787-9 aircraft scheduled for delivery between 2028 and 2031 and was granted options to purchase up to an additional 50 Boeing 787 aircraft. In addition, on September 29, 2023, United entered into an amendment to the A320 Family Purchase Agreement, dated December 19, 2019, as amended, with Airbus, pursuant to which United exercised purchase rights to purchase 60 A321neo aircraft scheduled for delivery between 2028 and 2030 and was granted purchase rights to purchase up to an additional 40 A321neo aircraft. The table above reflects the number of firm commitments related to these agreements as well as the contractual and expected aircraft deliveries.

During the nine months ended September 30, 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).

As of September 30, 2023, United had additional leases for 47 Embraer E175/E175LL regional jets under a CPA, 12 A321neo mainline aircraft, airport facilities and office space, none of which had commenced as of such date. These leases will commence between fourth quarter 2023 and 2026 with lease terms of up to 12 years.

Regional CPAs. During the nine months ended September 30, 2023, United amended several of its CPAs with certain of its regional carriers to increase the contractually agreed fees (carrier costs) paid to those carriers and to add additional aircraft that will replace existing aircraft near the end of their contractual terms. Separately, the Company terminated its CPA and related regional flight operations with Air Wisconsin in 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. 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 September 30, 2023, our estimated future payments through the end of the terms of our CPAs are presented in the table below:


(in billions)
Last three months of 2023	$	0.6
2024	2.2
2025	1.9
2026	2.1
2027	1.6
After 2027	5.7

Guarantees. As of September 30, 2023, United is the guarantor of approximately $1.9 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 2024 and 2041.

As of September 30, 2023, United is the guarantor of $81 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 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. The Company elected to apply the guidance in Accounting Standards Codification 848, Reference Rate Reform, to contracts and transactions that transitioned from the London Interbank Offered Rate (LIBOR) to SOFR. The application of this guidance did not have any material impact on the Company's financial statements. At September 30, 2023, the Company had $11.4 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 $8.2 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 September 30, 2023, the Company had approximately 102,000 employees, of whom approximately 83% were represented by various U.S. labor organizations.

In January 2023, the Company's more than 8,000 technicians and related employees represented by the International Brotherhood of Teamsters ratified an extension to their labor contract with United. The agreement becomes amendable in December 2024 and includes a one-year early opener provision that allows for bargaining on a successor agreement to begin in December 2023.

In May 2023, nearly 30,000 fleet service, passenger service, storekeepers, maintenance instructors and fleet technical instructors and related employees represented by the International Association of Machinists & Aerospace Workers ("IAM") ratified five agreements with United. The ratified agreements are effective through 2025. The Company recorded a one-time $48 million expense in conjunction with the ratification. Negotiations with the IAM will continue for agreements to cover security guards in California and central load planners.

In September 2023, the Company's pilots represented by ALPA ratified an agreement with United. The agreement includes numerous work rule changes and pay rate increases during the four-year term. The agreement also includes a provision for a one-time $765 million payment upon ratification.

Profit Sharing. Substantially all employees participate in profit sharing based on a percentage of pre-tax earnings, excluding special or non-recurring charges, profit sharing expense and share-based compensation. Profit sharing percentages range from 5% to 20% depending on the work group, and in some cases profit sharing percentages vary above and below certain thresholds. As part of the new collective bargaining agreement with the Air Line Pilots Association ("ALPA"), the thresholds were lowered retroactive to January 1, 2023 for the pilot work group. Eligible U.S. co-workers in each participating work group receive a profit sharing payout using a formula based on the ratio of each qualified co-worker's annual eligible earnings to the eligible earnings of all qualified co-workers in all domestic work groups. Eligible non-U.S. co-workers receive profit sharing based on the calculation under the U.S. profit sharing plan for management and administrative employees. The Company recorded profit sharing and related payroll tax expense of $301 million and $521 million in the three and nine months ended September 30, 2023, respectively. The Company recorded profit sharing expense of $8 million in both the three and nine months ended September 30, 2022. Profit sharing expense is recorded as a component of Salaries and related costs in the Company's statements of consolidated operations.

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 ticket 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 nine months ended September 30, 2023 and 2022, the Company recognized approximately $5.3 billion and $3.0 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 $1.1 billion and $3.0 billion of ancillary fees within passenger revenue in the three and nine months ended

September 30, 2023, respectively. The Company recorded $0.9 billion and $2.4 billion of ancillary fees within passenger revenue in the three and nine months ended September 30, 2022, respectively.

Frequent Flyer Accounting. The table below presents a roll forward of Frequent flyer deferred revenue (in millions):


	Three Months Ended September 30,				Nine Months Ended September 30,
	2023		2022		2023		2022
Total Frequent flyer deferred revenue - beginning balance	$	7,024	$	6,495	$	6,675	$	6,282

Total Frequent flyer deferred revenue - ending balance	$	7,076	$	6,578	$	7,076	$	6,578

In the three and nine months ended September 30, 2023, the Company recognized, in Other operating revenue, $0.7 billion and $2.0 billion, 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 Company recognized $0.6 billion and $1.7 billion, respectively, in the three and nine months ended September 30, 2022, related to those agreements. 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.
