During the six months ended June 30, 2025, the Company received seven additional cargo aircraft under the A&R ATSA, of which three aircraft were in-service. Subsequent to June 30, 2025, the Company received the eighth and final aircraft. As of the date of this filing, five aircraft were in-service. During the six months ended June 30, 2025, amendments were executed to extend the lease expiry terms for the three Owned Aircraft Held for Operating Lease, which now expire over various dates through the fourth quarter of 2026. During the six months ended June 30, 2025, an amendment was executed to extend the lease expiry terms for one of the Company's subleased aircraft, which now expires in the second quarter of 2026. During the six months ended June 30, 2025, the Company retired one owned aircraft. Of the 37 Owned aircraft and Owned Aircraft Held for Operating Lease as of June 30, 2025, 31 aircraft were financed, five aircraft have been pledged to support the ability to efficiently utilize the Company's four-year $75,000 revolving credit
facility (“Revolving Credit Facility”) entered into during March 2025, and one aircraft was unencumbered. See Note 5 for more information on the Company's Revolving Credit Facility.
During the six months ended June 30, 2025, the Company accepted delivery of one of the Owned Aircraft Held for Operating Lease that was leased to an unaffiliated airline, which will be inducted into the passenger fleet. Upon acquisition of the Owned Aircraft held for Operating Lease, the Company recognized a Maintenance Rights Asset associated with the acquired leases. Based on the maintenance condition of the one aircraft returned in 2025, the Maintenance Rights Asset settlement resulted in capitalized asset improvements of $4,697 and cash received from the lessee in excess of the Maintenance Rights Asset totaling $2,716. The cash received for end of lease compensation in excess of the Maintenance Rights Asset was recognized within Other Revenue in the Company’s Condensed Consolidated Statement of Operations.
During the six months ended June 30, 2024, the Company acquired one incremental aircraft and took control of two aircraft through finance lease arrangements, one of which was subsequently subleased to an unaffiliated airline. Upon expiry of the sublease, the aircraft will be redelivered to the Company and is expected to be inducted into the Company's passenger fleet. Further, the Company purchased one aircraft previously classified as a finance lease.
