IBM Airline Control Program, or ACP, was the operating system developed by IBM beginning about 1965. In contrast to previous airline transaction processing systems, the most notable aspect of ACP is that it was designed to run on most models of the IBM System/360 mainframe computer family. This departed from the earlier model in which each airline would have a different, machine-specific transaction system.
Development began with SABRE (Semi-Automatic Business Environment Research), Deltamatic, and PANAMAC. From these PARS (Programmed Airline Reservation System) was developed. In 1968 the control program, ACP was separated from PARS; PARS keeping the functions for processing airline reservations and related data
In February 1979, ACP became known as ACP/TPF and then just TPF (Transaction Processing Facility) as the transaction operating system became more widely implemented by businesses other than the major airlines.
Current IBM articles[1] reference the IBM Airline Control System (ALCS) and, for some cases, distinguish between ALCS and TPF.
