Combined Notes to the Financial Statements (Unaudited)	Jun. 30, 2022
Unusual or Infrequent Items, or Both [Abstract]
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 principal, 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, 2021 (the "2021 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 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 June 30,				Six Months Ended June 30,
	2022		2021		2022		2021
Domestic (U.S. and Canada)	$	7,819	$	3,767	$	12,905	$	5,878
Atlantic	2,481		585		3,570		995
Latin America	1,195		727		2,104		1,119
Pacific	617		392		1,099		700
Total	$	12,112	$	5,471	$	19,678	$	8,692

Advance Ticket Sales. All tickets sold at any given point in time have travel dates through the next 12 months. The Company defers amounts related to future travel in its Advance ticket sales liability account. The Company's Advance ticket sales liability also includes credits issued to customers on electronic travel certificates ("ETCs") and future flight credits ("FFCs"), primarily for ticket cancellations, which can be applied towards a purchase of a new ticket. ETCs are valid up to one year from the date of issuance; however, all ETCs issued on or before December 31, 2022 have been extended to December 31, 2023. FFCs are valid for 12 months from the original ticket date; however, all FFCs issued on or before December 31, 2022 have been extended to December 31, 2023. The Company is unable to estimate the amount of the ETCs and FFCs that will be used within the next 12 months and has classified the entire amount of the Advance ticket sales liability in current liabilities even though some of the ETCs and FFCs could be used after the next 12 months.

The Company estimates the value of Advance tickets sales that will expire unused ("breakage") and recognizes revenue at the scheduled flight date. To determine breakage, the Company uses its historical experience with expired tickets and other facts, such as recent aging trends, program changes and modifications that could affect the ultimate expiration patterns of tickets. Given the uncertainty of travel demand caused by the novel coronavirus ("COVID-19") pandemic, changes in our estimates of ETCs and FFCs that may expire unused could have a significant impact on revenue. Changes in estimates of breakage are recognized prospectively in proportion to the remaining usage of the related tickets.

In the three and six months ended June 30, 2022, the Company recognized approximately $4.2 billion and $2.6 billion, respectively, of passenger revenue for tickets that were included in Advance ticket sales at the beginning of those periods. In the three and six months ended June 30, 2021, the Company recognized approximately $1.5 billion and $1.4 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 seats, inflight amenities 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 $0.9 billion and $1.5 billion of ancillary fees within passenger revenue in the three and six months ended June 30, 2022, respectively. The Company recorded $0.5 billion and $0.8 billion of ancillary fees within passenger revenue in the three and six months ended June 30, 2021, respectively.

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


	Three Months Ended June 30,				Six Months Ended June 30,
	2022		2021		2022		2021
Total Frequent flyer deferred revenue - beginning balance	$	6,417	$	6,109	$	6,282	$	5,975
Total miles awarded	666		360		1,143		632
Travel miles redeemed	(566)		(267)		(888)		(390)

Total Frequent flyer deferred revenue - ending balance	$	6,495	$	6,185	$	6,495	$	6,185

In the three and six months ended June 30, 2022, the Company recognized, in Other operating revenue, $0.6 billion and $1.1 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. co-brand agreement. The Company recognized $0.4 billion and $0.8 billion, respectively, in the three and six months ended June 30, 2021, 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 liability. We determine the current portion of our frequent flyer liability based on expected redemptions in the next 12 months

- Definition

The entire disclosure of revenue from contract with customer to transfer good or service and to transfer nonfinancial asset. Includes, but is not limited to, disaggregation of revenue, credit loss recognized from contract with customer, judgment and change in judgment related to contract with customer, and asset recognized from cost incurred to obtain or fulfill contract with customer.

We consider all income sources, including other comprehensive income, in determining the amount of tax benefit allocated to results from operations.

(b) This AOCI component is included in the computation of net periodic pension and other postretirement costs (see Note 5 of this report for additional information).

Income Taxes	6 Months Ended
Income Taxes	Jun. 30, 2022
Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXESThe Company's effective tax rates for the three and six months ended June 30, 2022 were 28.3% and 18.9%, respectively. The effective tax rates for the three and six months ended June 30, 2021 were 23.0% and 22.6%, respectively. The effective tax rate represents a blend of federal, state and foreign taxes and includes the impact of certain nondeductible items. We have historically calculated the provision for income taxes during interim reporting periods by applying an estimate of the annual effective tax rate for the full fiscal year to income or loss for the reporting period. We have used a discrete effective tax rate method to calculate taxes for the three and six months ended June 30, 2022. We believe that, at this time, the use of the discrete method for the three and six months ended June 30, 2022 is more appropriate than the estimated annual effective tax rate method as the estimated annual effective tax rate method is not reliable due to a high degree of uncertainty in estimating annual pretax earnings.

- Definition

	June 30, 2022								December 31, 2021
	Total		Level 1		Level 2		Level 3		Total		Level 1		Level 2		Level 3
Cash and cash equivalents	$	16,885	$	16,885	$	—	$	—	$	18,283	$	18,283	$	—	$	—

Long-term investments:
Equity securities	142		142		—		—		229		229		—		—

Investments presented in the table above have the same fair value as their carrying value.

Restricted cash - current — Primarily includes amounts to be used for the payment of fees, principal and interest on senior secured notes and a secured term loan facility (the "MileagePlus Financing") secured by substantially all of the assets of Mileage Plus Holdings, LLC, a direct wholly-owned subsidiary of United.

Restricted cash - non-current — Primarily includes collateral associated with the MileagePlus Financing, collateral for letters of credit and collateral associated with facility leases and other insurance-related obligations.

Short-term investments — The short-term investments shown in the table above are classified as available-for-sale and have remaining maturities of approximately one year or less.

Equity securities — Represents equity and equity-linked securities (such as vested warrants) that make up United's investments in Azul Linhas Aéreas Brasileiras S.A., Clear Secure, Inc. and Archer Aviation Inc.

Other fair value information. The table below presents the carrying values and estimated fair values of financial instruments not presented in the tables above (in millions). Carrying amounts include any related discounts, premiums and issuance costs:


	June 30, 2022										December 31, 2021
	Carrying Amount		Fair Value								Carrying Amount		Fair Value
			Total		Level 1		Level 2		Level 3				Total		Level 1		Level 2		Level 3
Long-term debt	$	32,187	$	30,020	$	—	$	25,089	$	4,931	$	33,363	$	34,550	$	—	$	29,088	$	5,462

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 investments and Equity securities			Fair value is based on (a) the trading prices of the investment or similar instruments, (b) an income approach, which uses valuation techniques to convert future amounts into a single present amount based on current market expectations about those future amounts when observable trading prices are not available, or (c) 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.

Investments in Regional Carriers. As of June 30, 2022, United holds investments in two regional carriers that fly for the Company as United Express under its capacity purchase agreements. The combined carrying value of the investments was approximately $178 million as of June 30, 2022. United accounts for each investment using the equity method. During the second quarter of 2022, United divested its investment in ManaAir, LLC, the parent company of ExpressJet Airlines LLC.

Other Investments. United holds equity investments in a number of companies with emerging technologies and sustainable solutions. United also has equity investments in Avianca Group International Limited, a multinational airline holding company, and JetSuiteX, Inc., an independent air carrier doing business as JSX. 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 June 30, 2022, the carrying value of these investments was $331 million.

- Definition

Commitments and Contingencies Disclosure [Abstract]

COMMITMENTS AND CONTINGENCIES

Commitments. As of June 30, 2022, 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 Commitments (a)	Last Six Months of 2022	2023	After 2023
Airbus A321XLR	50	—	—	50
Airbus A321neo	70	—	12	58
Airbus A350	45	—	—	45
Boeing 737 MAX	364	50	109	205
Boeing 787	8	8	—	—
(a) United also has options and purchase rights for additional aircraft.

The aircraft listed in the table above are scheduled for delivery through 2030. 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. Furthermore, Boeing notified United that seven Boeing 737 MAX aircraft and three Boeing 787 aircraft scheduled for delivery in 2022, as shown in the table above, are now expected to deliver in 2023.

In the first half of 2022, United gave notice of its intent to exercise options to purchase, in 2023, eight Boeing 737 MAX aircraft that are currently leased under sale and leaseback arrangements.

The table below summarizes United's commitments as of June 30, 2022, which include aircraft and related spare engines, aircraft improvements and non-aircraft capital commitments (in billions):


Last six months of 2022	$	4.8
2023	7.8
2024	5.4
2025	4.4
2026	3.4
After 2026	8.8
	$	34.6

Legal Contingencies. The Company has certain contingencies resulting from litigation and claims incident to the ordinary course of business. As of June 30, 2022, management believes, after considering a number of factors, including (but not limited to) the information currently available, the views of legal counsel, the nature of the contingencies to which the Company is subject and prior experience, that its defenses and assertions in pending legal proceedings have merit and the ultimate disposition of any pending matter will not materially affect the Company's financial position, results of operations or cash flows. The Company records liabilities for legal claims when it is probable that a loss will be incurred and the amount is reasonably estimable. These amounts are recorded based on the Company's assessments of the likelihood of their eventual disposition.

During the three months ended June 30, 2022, the Company recorded charges of $94 million as a result of a number of recent decisions, including one involving another carrier, that appear to impact the Company's ability to successfully assert, in certain cases, that federal law preempts state and local laws that conflict with union contracts and/or federal requirements.

Guarantees. As of June 30, 2022, 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 June 30, 2022, United is the guarantor of $99 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), 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 June 30, 2022, the Company had $13.1 billion of floating rate debt with remaining terms of up to approximately 10 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 10 years and an aggregate balance of $9.9 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.

Credit Card Processing Agreements. The Company has agreements with financial institutions that process customer credit card transactions for the sale of air travel and other services. Under certain of the Company's credit card processing agreements, the financial institutions in certain circumstances have the right to require that the Company maintain a reserve equal to a portion of advance ticket sales that has been processed by that financial institution, but for which the Company has not yet provided the air transportation. Such financial institutions may require additional cash or other collateral reserves to be established or additional withholding of payments related to receivables collected if the Company does not maintain certain minimum levels of unrestricted cash, cash equivalents and short-term investments (collectively, "Unrestricted Liquidity"). The Company's level of Unrestricted Liquidity as of June 30, 2022 is substantially in excess of these minimum levels.

Labor. As of June 30, 2022, the Company had approximately 91,200 employees, of whom approximately 85% were represented by various U.S. labor organizations. This total includes employees who elected to voluntarily separate from the Company pursuant to voluntary leave programs and voluntary separation programs offered in 2020 and 2021 but who were still on pre-separation leave of absence with pay and benefits as of June 30, 2022.

Debt Disclosure [Abstract]

DEBT

As of June 30, 2022, 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 June 30, 2022, UAL and United were in compliance with their respective debt covenants.

The table below presents the Company's contractual principal payments (not including $447 million of unamortized debt discount, premiums and debt issuance costs) at June 30, 2022 under then-outstanding long-term debt agreements (in millions):


Last six months of 2022	$	1,519
2023	2,929
2024	3,908
2025	3,375
2026	5,148
After 2026	15,755
	$	32,634

In the second quarter of 2022, United borrowed $220 million aggregate principal amount from a financial institution to finance the purchase of aircraft. The notes evidencing these borrowings, which are secured by the related aircraft, mature in 2034 and have interest rates of 4%.

Fair Value Measurement Inputs and Valuation Techniques

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 investments and Equity securities			Fair value is based on (a) the trading prices of the investment or similar instruments, (b) an income approach, which uses valuation techniques to convert future amounts into a single present amount based on current market expectations about those future amounts when observable trading prices are not available, or (c) 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.
