REVENUES
The Company accounts for contracts with our Partner Airlines under ASC 606, Revenue from Contracts with Customers, and ASC 842, Leases, as applicable, when each party has committed to perform under the contract, each party’s rights and payment terms have been established, when the contract has commercial substance, and when collectability of amounts due under the contract is probable. Under CPAs with our Partner Airlines, the Company has
committed to perform various flight services and maintenance activities classified as regional jet services. Within regional jet services, flight services represent a series of distinct activities accounted for as a single performance obligation satisfied over time as flights are completed. The Company recognizes certain maintenance activities as separate performance obligations, which are satisfied as the related distinct service is complete. Substantially all of the Company’s revenues are generated from regional jet services.
Revenues associated with regional jet services are generally derived from (i) a fixed fee per departure, flight hour, and/or block hour of time incurred and a fixed rate for available-to-schedule aircraft, payable on a monthly basis; and (ii) a premium amount which is earned monthly and quarterly by maintaining minimum aircraft utilization levels and exemplary operating results. To the extent that minimum targets are not achieved, the Company could be subject to financial penalties. These fixed-fee rates are contractually subject to periodic economic adjustment. The Company additionally receives reimbursement from our Partner Airlines for direct expenses incurred such as qualifying maintenance activities, property taxes, and miscellaneous operating expenses. Certain charges such as fuel, landing fees, and certain ownership costs are generally paid directly by the Partner Airlines, although the charges were incurred by the Company in ongoing operations. The Company refers to these charges as “Partner direct charges.” Pass-through charges are primarily recorded to revenues and the corresponding operating expense on a gross basis. Pass-through charges recorded on a net basis are not material.
Amounts recognized as regional jet services revenues are measured at the contractual amount the Company expects it will be entitled to in exchange for the promised services. The Company allocates the transaction price as flights are completed with variable consideration that relates specifically to the Company’s efforts in delivering each flight recognized in the period in which the individual flight is completed and measured on a monthly basis. The Company records an estimate for incentive revenue based on our expected performance at the end of each period. These estimates are derived under accounting guidance related to variable consideration constraints and based on amounts expected to be collected. The Company has concluded that allocating the variability directly to individual flights results in an overall allocation meeting the objectives in ASC 606. This results in a pattern of revenue recognition that generally follows the variable amounts billed from the Company to Partner Airlines. As allowed with ASC 606, the Company has elected to apply practical expedients to expense significant financing components and the incremental costs of obtaining a contract as incurred.
A portion of the Company’s compensation under its CPAs is designed to reimburse the Company for certain aircraft ownership costs. The Company has concluded that a component of its revenue under the CPAs is deemed to be embedded lease revenue and as such, agreements identify the right-of-use of a specific type and number of aircraft over the term of the CPA. Embedded lease revenue associated with the Company’s CPAs is accounted for as an operating lease under ASC 842, Leases.

(1)Certain of the Company’s CPAs include embedded leases for the right-of-use of the regional jet aircraft. The Company also leases 31 aircraft not under CPAs to American Airlines. The corresponding rental income is classified herein.
LIFT Academy recorded tuition revenue of $23.2 million, $19.3 million, and $11.6 million during the years ended December 31, 2025, 2024, and 2023, respectively. Tuition payments received from students are recognized as deferred revenue and reflected in accrued and other liabilities in the consolidated balance sheets and are recognized on a systematic basis as students progress throughout their respective training programs.
Amounts recognized as revenues in the consolidated statements of operations are subject to certain estimates, which could materially impact the timing and consideration determined under the contract. Such estimates include (i) expected contract terms from material modifications to the fixed-fee capacity purchase agreements which are expected to be made in the future and (ii) the extent to which disputes in contract interpretation arise.
Receivables and contract assets—Receivables represent a right to consideration for promised services which have been transferred to customers. The Company records provisions for credit losses using an expected credit losses model on the basis of specific identification and historical collection experience. For more information on credit losses, refer to Note 17, Valuation and Qualifying Accounts.
Contract assets are generated from the partial satisfaction of certain performance obligations, generally related to the delivery of aircraft maintenance services, under customer contracts whereby the Company has the right to consideration for services transferred or provided to its customers. Other current assets—related parties and other non-current assets—related parties in the consolidated balance sheets consist entirely of contract assets, which have been appropriately reduced for the applicable financing component. The Company expects to collect all current amounts within the next twelve months, while non-current amounts will be collected over the period from 2027 to 2030.
Contract liabilities—Contract liabilities consist of deferred revenues for which the Company has received customer payment for undelivered services. In addition, the Company periodically carries out capital projects on behalf of its Partner Airlines, generally pertaining to aircraft fleet and livery improvements. Revenues of this nature are recognized over time, depicting the pattern of transfer of control of services, resulting in ratable recognition of revenues over the remaining term of the CPA, ranging from 2026 - 2036.
Current and non-current deferred revenues are recorded to accounts payable and accrued and other liabilities-related parties and other non-current liabilities-related parties, respectively, in the consolidated balance sheets. The Company recognized $16.1 million, $13.7 million, and $10.8 million of the deferred revenue to revenues in the consolidated statements of operations during the years ended December 31, 2025, 2024, and 2023, respectively, which was previously included in contract liabilities at December 31, 2024, 2023, and 2022, respectively. Current contract liabilities were $35.9 million and $22.7 million as of December 31, 2025 and 2024, respectively.

About Revenue Disclosures

Revenue disclosures under ASC 606 explain how a company identifies performance obligations, allocates transaction prices, and determines when revenue is recognized. This section is essential for understanding whether reported revenue reflects genuine economic activity or aggressive accounting choices. Analysts examine the mix of point-in-time versus over-time recognition, which directly affects revenue timing and comparability.

Key signals: rising contract liabilities (deferred revenue) suggest strong future revenue visibility, while declining contract assets may indicate slowing project milestones. Watch for variable consideration estimates — rebates, returns, and performance bonuses that require management judgment. Significant changes in disaggregated revenue by geography or product line can reveal shifting business mix before it appears in headline numbers. Compare revenue growth against contract liability growth to assess sustainability, and scrutinize any changes in the timing of recognition that coincide with earnings pressure.
