Airlines have divested most of their direct holdings to dedicated GAS companies, who make their systems accessible to consumers through Internet gateways. Modern Edges typically allow users to book hotel rooms and rental cars as well as airline tickets. They also provide access to railway reservations and bus reservations In some markets although these are not always integrated with the main system. History Origins In 1946, American Airlines installed the first automated booking system, the experimental electromechanical Reservoirs.
A newer machine with temporary storage based on a magnetic drum, the Magnetron’s Reservoirs, soon followed. This system proved successful, and was soon being used by several airlines, as well as Sheraton Hotels and Goodyear for inventory control. It was seriously hampered by the need for local human operators to do the actual lookups; ticketing agents would have to call a booking office, whose operators would direct a small team operating the Reservoirs and then read the results over the telephone.
There was no way for agents to directly query the system Computer reservation system Computer reservation systems are primarily used for Inventory management by airlines, hotels, and other tourism and hospitality enterprises. Enhanced and sophisticated CARS configurations and functionality offer companies an integrated elution for several processes including managing sales, bookings, customer relationship management and service, other marketing practices, yield management, payments and accounting even at a one-to-one customer basis (Kigali et al. 2001). Integrated Cars aim to organize companies Internally by enabling organizational reengineering/ restructuring changes that In turn streamline processes and foster functional efficiency and effectiveness. Moreover, the term central reservation system refers to the CARS developed by hotel chains for centralizing the reservation process f all their affiliated properties and enabling multicast management. The major benefits of such systems are operational efficiencies and staff reductions.
Abraham (1988) briefly outlined the processes, functionalities, and benefits of a CARS as follows: * Flexible inventory booking capability * Immediate availability update * Overbooking management * Complete and detail reservations screen * Individual and group reservations and blockings * Travel agency Information entry, activity reports and commission handling * Reservations linked to city ledger * Advance deposit posting and auditing Request for deposit and deposit received * Modifications and cancellation confirmations * Free-form comments field on all reservations * System generated confirmation numbers on all reservations * User identification * Confirmations printed automatically or on demand * Forecast reports * Current and future dates to five years historical information * Detailed inventory control * No-shows reports and handling (charging and billing) * Customer information – past, present, future -retained in system. Galileo CARS Galileo is a computer reservations system (CARS) owned by Travelers. As of 2002, it ad a 26. 4% of worldwide CARS airline bookings. L] In addition to airline reservations, the Galileo CARS is also used to book train travel, cruises, car rental, and hotel rooms. The Galileo system was moved from Denver, Colorado, to the Worlds data center in Atlanta, Georgia, on September 28, 2008, following the 2007 merger of Travelers and World span (although they now share the same decanter, they continue to be run as separate systems). Galileo is subject to the Caps II and its successor Secure Flight program for the selection of passengers with a risk profile. Galileo is a member f DATA, TOT and SITS. History Galileo traces its roots back to 1971 when United Airlines created its first computerized central reservation system under the name Apollo.
During the sass and early sass, a significant proportion of airline tickets were sold by travel agents. Flights by the airline owning the reservation system had preferential display on the computer screen. Due to the high market penetration of the Saber and Apollo systems, owned by American Airlines and United Airlines, respectively, Worlds and Galileo were created by other airline groups in an attempt to gain market share n the computer reservation system market and, by inference, the commercial airline market.  Galileo was formed in 1987 by nine European carriers –British Airways, KILL Royal Dutch Airlines, Altair, Sassier, Austrian Airlines, Olympic, Sabina, Air Portugal and Are Lingua. 3] In response and to prevent possible government intervention, United Airlines spun-off its Apollo reservation system, which was then controlled by Covina. Galileo International was born when Covina acquired Rupee’s Galileo and merged it with the Apollo system in 1992.  The Apollo reservation system is still used by United Airlines and Galileo International now part of Travelers GAS) travel agency customers in the United States, Canada, Mexico, and Japan. Galileo I-J was originally created from Tragicomic which was the world’s first multi-access reservations system using the technology developed by Video. Tragicomic was a company launched by Video, British Airways, British Caledonia and CLC in 1976 which in 1988 became Galileo I-J. Recent Updates by the Company directly.
Southwest Airlines has entered into a marketing agreement with Apollo/ Galileo and travel agents are now able to book reservations directly on Southwest. These direct connects offer the possibility to sell ancillary services and to differentiate oneself from the competition.  The development team at Travelers has developed an online search tool called ASK Travelers where registered users can go and find out the answers to their frequently asked questions and queries. After the take over of Worlds by Travelers, now both the entities are Jointly called as Travelers GAS. In India, the distribution of both the GAS vests with Interlope.  In October 2009, Travelers and Amadeus held talks for a possible merger which would lead to the biggest GAS in the world.
