This is a big deal. Sabre was the first automated reservation system and it has been around for about ten years. A long time ago it would have to match 2 Million combinations a day with discounts and all kinds of stuff.

What with the airline business down, I don't know but I bet they were still running old IBM mainframe stuff.

Does anyone know what they switched from???? What are the software issues?


I dont really know! However EDS did a lot with IBM, so I would imagine they were using a 360. I dont believe an AS-400 would carry the load, perhaps a farm of em would, dont really know. Mainframes were never my bag.

I did run into EDS on a few occassions.

I did replace a AS-400 for a company with an IBM server several years ago, the 400 was costing to much to maintain in the companys opinion.

Wasn't EDS started by...senior moment here, you know, the guy who ran for Pres., measure twice, cut once.
He worked for IBM, told em the $$$ was in software, IBM disagreed so he quit, started EDS I think.
If so, turns out he was correct.

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.
