ATSG Airline to Operate Six More 767 Freighters for Amazon Air

WILMINGTON, OH, September 9, 2020 – Air Transport Services Group, Inc. (Nasdaq: ATSG), the leading provider of medium wide-body aircraft leasing, air transportation and related services, today announced that ATSG will operate six more Boeing 767 freighters on behalf of Amazon Air under an existing CMI (Crew, Maintenance and Insurance) agreement with ATSG’s subsidiary, Airborne Global Solutions.

This commitment from Amazon applies to the first six of the twelve 767 freighters that Amazon agreed in May to lease from ATSG’s Cargo Aircraft Management (CAM) subsidiary by the end of 2021, each lease having a ten-year term. The first of the six CAM-leased aircraft began operation for Amazon Air in 2020 and the remaining five CAM-leased aircraft will begin operation in 2021. Including these six aircraft, ATSG projects that its airlines will operate 38 Boeing 767s for Amazon Air by April of next year, 36 of which are leased to Amazon by CAM. The CMI agreement was amended in December 2018 to extend through March 2026, with an option to extend for an additional three years.

ATSG subsidiary Air Transport International will fly all six of the 767s to be added to the Amazon CMI agreement.
