LEASES

3 Months Ended

Mar. 31, 2023

Leases primarily pertain to certain controlled aircraft, corporate headquarters and operational facilities, including aircraft hangars, which are all accounted for as operating leases. We sublease an aircraft hangar at Cincinnati/Northern Kentucky International Airport from Delta. Certain of these operating leases have renewal options to further extend for additional time periods at our discretion.

Our leases do not contain residual value guarantees, covenants or other associated restrictions. We have certain variable lease agreements with aircraft owners that contain payment terms based on an hourly lease rate multiplied by the number of flight hours during a month. Variable lease payments are not included in the right-of-use asset and lease liability balances but rather are expensed as incurred.
