Sabre, which owns travelocity (if your interested), is the largest GDS in the world. It was previously owned by AMR corp and was the in-house CRS for American Airlines.

Historically, like to other GDSs, Sabre ran on IBM mainframes.

Built on the Transaction Processing Facility (TPF) mainframe databases first developed by IBM for the airlines in the 1960s, these reservation systems, as they exist now, have layers of archaic business rules built one on top of another in 360 Assembler language. Each change has to take into account the previous 30 or 40 years' worth of rules. With a shortage of TPF programmers, those in the workforce are expensive to hire, so any programming changes to the business rules in a fare-pricing structure take a long time to make and cost a lot of money.
