Group - Sabre computer system

Sabre is a computer reservations system/global distribution system (GDS) used by airlines, railways, hotels, travel agents and other travel companies. Sabre GDS is a unit of Sabre Holdings' Sabre Travel Network division. Current North American hosted carriers include Alaska Airlines, American Airlines, WestJet, Cape Air, Frontier Airlines, Hawaiian Airlines, Mesa Airlines, and Midwest Airlines. Its current IATA code is 1S. However some internal areas are still under 1W. The Sabre datacenter is in Tulsa, Oklahoma-US and was subject to the Computer Assisted Passenger Prescreening System II and is intended to be part of the successor Secure Flight program for the selection of passengers with a risk profile, sometime in 2008-10.[citation needed] Sabre was developed in order to help American Airlines improve the way in which the airline booked reservations. By the 1950s, American Airlines was facing a serious challenge in its ability to quickly handle airline reservations in an era that witnessed high growth in passenger volumes in the airline industry. Before the introduction of Sabre, the airline's system for booking flights was entirely manual, having developed from the techniques originally developed at its Little Rock, Arkansas reservations center in the 1920s. In this manual system, a team of eight operators would sort through a rotating file with cards for every flight. When a seat was booked, the operators would place a mark on the side of the card, and knew visually whether it was full. This part of the process was not all that slow, at least when there were not that many planes, but the entire end-to-end task of looking for a flight, reserving a seat and then writing up the ticket could take up to three hours in some cases, and 90 minutes on average. The system also had limited room to scale. It was limited to about eight operators because that was the maximum that could fit around the file, so in order to handle more queries the only solution was to add more layers of hierarchy to filter down requests into batches.
