 ATA Connection

C8 and ATA Connection are the defunct IATA code designator and DBA name of Chicago Express Airlines, which in its later years was doing business as ATA Connection, and was the trademark codeshare name and brand used by the renamed parent company of ATA Holdings Inc. for ATA Airlines (formerly known as American Trans Air), the principal operating unit for flights to smaller Midwestern cities.C8 - the ATA Connection, as a branded regional feeder operation, ceased being used when the remaining assets of Chicago Express were completely divested from AMTRAN, INC.'s successor company early in 2006, and some months before that when the fleet was withdrawn from service, owned aircraft parked, and leased airplanes returned to their lease owners.
