Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The unaudited interim condensed consolidated financial statements and accompanying notes have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) for interim financial reporting and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the financial information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of the Company’s management, the unaudited condensed consolidated financial statements include all adjustments necessary for the fair presentation of the Company’s balance sheet as of March 31, 2023, and its results of operations, including its comprehensive loss, stockholders' equity and its cash flows for the three months ended March 31, 2023 and 2022. All adjustments are of a normal recurring nature. The results for the three months ended March 31, 2023 are not necessarily indicative of the results to be expected for any subsequent quarter or for the fiscal year ending December 31, 2023. These unaudited interim condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2022, filed with the Securities and Exchange Commission (the “SEC”) on March 31, 2023.
Principles of Consolidation	Principles of Consolidation The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. We consolidate Wheels Up Partners MIP LLC (“MIP LLC”) and record the profits interests held in MIP LLC that Wheels Up does not own as non-controlling interests (see Note 12). All intercompany transactions and balances have been eliminated in consolidation.
Use of Estimates	Use of Estimates Preparing the condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates due to risks and uncertainties. The most significant estimates include, but are not limited to, the useful lives and residual values of purchased aircraft, the fair value of financial assets and liabilities, acquired intangible assets, goodwill, contingent consideration and other assets and liabilities, sales and use tax, the estimated life of member relationships, the determination of the allowance for credit losses, impairment assessments, the determination of the valuation allowance for deferred tax assets and the incremental borrowing rate for leases.
Foreign Currency Translation Adjustments	Foreign Currency Translation Adjustments Assets and liabilities of foreign subsidiaries, where the functional currency is not the United States (“U.S.”) dollar, have been translated at period-end exchange rates and profit and loss accounts have been translated using weighted-average exchange rates. Adjustments resulting from currency translation have been recorded in the equity section of the condensed consolidated balance sheets and the condensed consolidated statements of other comprehensive loss as a cumulative translation adjustment.
Adopted Accounting Pronouncements and Accounting Pronouncements Note Yet Effective	Adopted Accounting Pronouncements and Accounting Pronouncements Note Yet Effective There have been no recent accounting pronouncements, changes in accounting pronouncements or recently adopted accounting guidance during the three months ended March 31, 2023 that are of significance or potential significance to us.
