ATSG is an aviation holding company that has operated since 1980, evolving from its origins in express freight to become a diversified player across aircraft leasing, airline operations, and aviation services. The company traces its current structure to 2003, when DHL's acquisition of Airborne Express's freight operations led to the formation of Air Transport Services Group, which retained the airline and maintenance operations. Today, ATSG operates a fleet of over 100 aircraft and employs approximately 5,300 people globally.
The company's core business centres on freighter leasing and ACMI (Aircraft, Crew, Maintenance, Insurance) services, where it claims leadership in the midsize freighter market and positions itself as the world's largest freighter lessor. Through Cargo Aircraft Management, a subsidiary, ATSG is the largest global lessor of Boeing 767 Freighters. The company also owns and operates multiple airlines - ABX Air, Air Transport International, and Omni Air International - which serve as both operational platforms and revenue generators within its integrated aviation ecosystem.
Beyond leasing and airline operations, ATSG provides aircraft maintenance, aircrew training, passenger-to-freighter conversions, and logistics services. This portfolio allows the company to offer comprehensive solutions across the aviation supply chain, from asset leasing to end-to-end operational management for customers requiring cargo capacity and related services.
