(7) Leases, Commitments, Guarantees and Contingencies

The Company leases property and equipment under operating leases. For leases with durations longer than 12 months, the Company recorded the related operating lease right-of-use asset and operating lease liability at the present value of lease payments over the term. The Company used its incremental borrowing rate to discount the lease payments based on information available at lease commencement.

Aircraft

As of March 31, 2026, excluding aircraft financed by the Company’s major airline partners that the Company operates for them under contract, the Company leased eight aircraft under long-term lease agreements with remaining terms ranging from three to four years. The Company is subleasing these eight aircraft to a third party.

Airport facilities

The Company has operating leases for facility space including airport terminals, office space, cargo warehouses and maintenance facilities. The Company generally leases this space from government agencies that control the use of the various airports. The remaining lease terms for facility space vary from one month to 30 years. The Company’s operating leases with lease rates that are variable based on airport operating costs, use of the facilities or other variable factors are excluded from the Company’s right-of-use assets and operating lease liabilities in accordance with accounting guidance.

Leases

As of March 31, 2026, the Company’s right-of-use assets were $82.9 million, the Company’s current maturities of operating lease liabilities were $20.8 million, and the Company’s noncurrent lease liabilities were $62.1 million. During the three months ended March 31, 2026, the Company paid $11.9 million under operating leases reflected as a reduction from operating cash flows.

In addition to the table above, in 2024, the Company entered into a master equipment purchase agreement with another airline to acquire certain airframes and engines and lease the assets back to the airline under a five-year term. The Company accounted for the transaction as a failed sale-leaseback in accordance with ASC 842 as the criteria for a sale were not met. At March 31, 2026, the Company estimated the remaining financing obligation under the agreement will be between $20.0 million and $25.0 million and anticipated closing on the remaining financings during 2026.

Guarantees

In 2022, the Company agreed to guarantee $19.8 million of debt for a 14 CFR Part 135 air carrier. The debt is secured by the Part 135 air carrier’s aircraft and engines and has a five-year term. In exchange for providing the guarantee, the Company received 6.5% of the guaranteed amount as consideration, payable in the estimated value of common stock of the Part 135 air carrier, all of which was sold in 2023. The purpose of this guarantee is to help reduce the financing costs of aircraft for the third party in an effort to increase the potential number of commercial pilots in the Company’s hiring pipeline. The balance of the debt under the guarantee was $12.2 million as of March 31, 2026.

The Company recorded the estimated credit loss associated with the guarantees based on publicly available historical default rates issued by a third party for companies with similar credit ratings, factoring the collateral and guarantee term.
