Performance Obligations
A performance obligation is a promise in a contract to transfer a distinct service to the customer and is the basis of revenue recognition. To determine the proper revenue recognition method for contracts, we used judgment to evaluate whether two or more contracts should be combined and accounted for as a portfolio and whether the combined or single contract should be accounted for as more than one performance obligation.
Transaction Price
The transaction prices for each of our primary revenue streams are as follows:
•Flights — The fixed quoted amount including any flight credits.
•Memberships — The one-time initiation fee, which was discontinued starting in July 2024, less any flight credits, when signing up (if applicable) and annual membership fees for all years thereafter.
•Aircraft management — The fixed monthly fee to manage the aircraft over the contractual term plus the recovery of owner-incurred expenses and recharge costs that are based on the expenses we incur to operate and maintain the aircraft.
•Other — Generally based on contractual amounts or time and materials incurred for the work performed or services rendered.
If there is a group of performance obligations bundled in a contract, the transaction price is allocated based upon the relative standalone selling prices of the promised services underlying each performance obligation.
Payment Terms
Under standard payment terms, the member or customer agrees to pay the full stated price in the contract, in advance of the service. We do not provide financing for transactions. Revenue in the consolidated statements of operations is presented net of discounts and incentives of $12.1 million, $10.6 million and $9.6 million for the years ended December 31, 2025, 2024 and 2023, respectively. We generally do not issue refunds for flights unless there is a failure to meet a service obligation with respect to such flight. Refunded amounts for annual membership and initiation fees are granted to some customers that no longer wish to remain members following their first flight and were $0.7 million, $2.1 million and $3.5 million for the years ended December 31, 2025, 2024 and 2023, respectively.

Costs to Obtain Contract
Commissions are granted to certain employees and consultants separately for the initial sales of memberships, additional subsequent contract renewals, when members purchase Membership Funds on their accounts or for charter flights. In addition, members are eligible to receive a credit if they refer a new customer who signs up for a membership in the Wheels Up program. For periods prior to the year ended December 31, 2024, commissions were also granted for the execution of aircraft management agreements, additional subsequent contract renewals and performance over the contractual term. The cost of commissions and referral fees are capitalized as an asset on the consolidated balance sheets as these are incremental amounts directly related to attaining a contract with a member. Capitalized costs related to sales commissions and referral fees were $8.4 million, $8.8 million and $8.1 million for the years ended December 31, 2025, 2024 and 2023, respectively.
As of December 31, 2025 and 2024, capitalized sales commissions and referral fees of $4.8 million and $4.6 million, respectively, were included in Other current assets, and $0.1 million and $0.3 million, respectively, were included in Other non-current assets on the consolidated balance sheets.
Amounts capitalized for certain costs incurred to obtain a contract are periodically reviewed for impairment and amortized on a straight-line basis concurrently over the same period of benefit in which the associated contract revenue is recognized. Amortization expense related to capitalized sales commissions and referral fees is included in Sales and marketing expense in the consolidated statements of operations and was $8.5 million, $8.8 million and $9.5 million for the years ended December 31, 2025, 2024 and 2023, respectively.
