They're probably still using USAS. Written in 1969. In COBOL.
Someone at Sabre claimed the booking software had been rewritten in Java. I worked at a place that had over 350 people working in airline booking and saw that product in action. It was a Uniscope terminal emulator running in Java.
USAS is Unisys software for airline booking, and from someone in upper management in Unisys from a party a few years all Unisys does now is train people in COBOL to keep the 1969 booking code working. Unisys system probably still have Uniscope terminal code and drivers, just like most linux system still do VT100, 101, 200, etc terminal emulation. I recognized the Uniscope terminal emulator because I used to install them, and wrote some basic db front ends in a Unisys coding system called 'Scop' - an XML-like way of building quick multi-db input screens. It has a particularly characteristic look which is what the Sabre java client running in the browser looked exactly like.
