About the SABRE Distribution System
SABRE is a centralized real-time processing operating system (RT TPOS).
SABRE is one of the largest globalizers or global distribution systems (GDS) in the market, as well as being the oldest.
It was developed by IBM, in conjunction with American Airlines, as a software system for making flight reservations through a computerized system.
SABRE stands for Semi Automated Business-Related Enterprise, which made it possible to significantly speed up air reservations.
Later this system would be expanded to other airlines as it was developed over time.
PF keys are saved in a PFKEY extension file, along with the usual Saber system commands.
