Leases

As of March 31, 2025, we leased 23 airport facilities, office space, and other property and equipment under

non-cancelable

operating leases. The leases generally require us to pay all taxes, maintenance, insurance, and other operating expenses. Operating leased expense is recognized as a rental expense on a straight-line basis over the lease term, net of lessor rebates and other incentives.

Aggregate rental expense under all aircraft, equipment and facility leases totaled approximately $2.8 million and $4.6 million for the three months ended March 31, 2025 and March 31, 2024, respectively, and $6.1 million and $12.6 million for the six months ended March 31, 2025 and March 31, 2024, respectively.

The components of our lease costs were as follows (in thousands):


	Three Months Ended March 31,				Six Months Ended March 31,

Leases

At September 30, 2024, the Company leased 32 aircraft, airport facilities, office space, and other property and equipment under non-cancelable operating leases. The operating leases require the Company to pay taxes, maintenance, insurance, and other operating expenses. Rental expense is recognized on a straight-line basis over the lease term, net of lessor rebates and other incentives. The Company expects that, in the normal course of business, such operating leases that expire will be renewed or replaced by other leases, or the property may be purchased rather than leased. Aggregate rental expense under all operating aircraft, equipment and facility leases totaled approximately $13.9 million, $12.2 million, and $43.4 million for the fiscal years ended September 30, 2024, 2023, and 2022, respectively.

At September 30, 2024, the Company leased

two

aircraft under non-cancelable finance leases. Basic rent on finance leases is paid monthly and at the end of the lease term. At the end of the lease term, the Company has the option to purchase the aircraft and engines for most of the finance leases. These finance leases are reflected as finance lease obligations of $4.7 million on our consolidated balance sheet as of September 30, 2024.
