ABX Air, Inc. (ABX) was recently a wholly owned subsidiary of Airborne, Inc. (Airborne). On August 15, 2003, ABX was separated from Airborne and became an independent, publicly owned company. ABX is an airline providing air cargo transportation and hub services within the United States and to Canada and Puerto Rico. The Company operates and maintains an in-service fleet of 115 aircraft. Through a network of 12 hubs in the United States, the Company provides package sorting and handling services. ABX utilizes contracted line-haul from third-party trucking companies to transport deferred delivery cargo within its network. Deferred delivery cargo must be delivered at a specific time, but is less time sensitive than express freight typically transported by its aircraft. ABX does not provide local pickup and delivery services to consumers.
