{{Short description|Computerized reservation systems}}
Computer reservation systems, or
central reservation systems (
CRS), are
computerized systems used to store and retrieve information and conduct transactions related to
air travel,
hotels,
car rental, or other activities. Originally designed and operated by airlines, CRSs were later extended for use by
travel agencies, and
global distribution systems (GDSs) to book and sell tickets for multiple airlines. Most airlines have
outsourced their CRSs to GDS companies,NEWS, The ineluctable middlemen,
weblink The Economist, 25 August 2012, 29 August 2012, which also enable consumer access through
Internet gateways.Modern GDSs typically also allow users to book hotel rooms, rental cars, airline tickets as well as other activities and tours. They also provide access to railway reservations and bus reservations in some markets, although these are not always integrated with the main system. These are also used to relay computerized information for users in the hotel industry, making reservation and ensuring that the hotel is not overbooked.
Airline reservations systems may be integrated into a larger
passenger service system, which also includes an airline inventory system and a
departure control system. The current centralised reservation systems are vulnerable to network-wide system disruptions.MAGAZINE, Stewart, Jack, How a Computer Outage Can Take Down a Whole Airline, Wired,

History

MARS-1
The
MARS-1 train ticket reservation system was designed and planned in the 1950s by the
Japanese National Railways' R&D Institute, now the
Railway Technical Research Institute, with the system eventually being produced by
Hitachi in 1958.
ãHitachi and Japanese National Railwaysã MARS-1,
Information Processing Society of Japan It was the world's first seat reservation system for trains.
Early Computers: Brief History,
Information Processing Society of Japan The MARS-1 was capable of reserving seat positions, and was controlled by a
transistor computer with a
central processing unit and a 400,000-bit magnetic drum memory unit to hold seating files. It used many
registers, to indicate whether seats in a train were vacant or reserved to accelerate searches of and updates to seat patterns, for communications with terminals, printing reservation notices, and
CRT displays.
Remote access
In 1953
Trans-Canada Airlines (TCA) started investigating a computer-based system with remote
terminals, testing one design on the
University of Toronto's
Ferranti Mark 1 machine that summer. Though successful, the researchers found that input and output was a major problem.
Ferranti Canada became involved in the project and suggested a new system using
punched cards and a
transistorized computer in place of the unreliable
tube-based Mark I. The resulting system,
ReserVec, started operation in 1962, and took over all booking operations in January 1963. Terminals were placed in all of TCA's ticketing offices, allowing all queries and bookings to complete in about one second with no remote operators needed.In 1953 American Airlines
CEO C. R. Smith chanced to sit next to R. Blair Smith, a senior
IBM sales representative, on a flight from
Los Angeles to
New York. C.R. invited Blair to visit their Reservisor system and look for ways that IBM could improve the system. Blair alerted
Thomas Watson Jr. that American was interested in a major collaboration, and a series of low-level studies started. Their idea of an automated
airline reservation system (ARS) resulted in a 1959 venture known as the
Semi-Automatic Business Research Environment (SABRE), launched the following year.R. Blair Smith, OH 34. Oral history interview by Robina Mapstone, May 1980. Charles Babbage Institute, University of Minnesota, Minneapolis.

weblink |date=2002-08-16 }} By the time the network was completed in December 1964, it was the largest civil
data processing system in the world.Other airlines established their own systems.
Pan Am launched its PANAMAC system in 1964.
Delta Air Lines launched the Delta Automated Travel Account System (DATAS) in 1968.
United Airlines and
Trans World Airlines followed in 1971 with the
Apollo Reservation System and
Programmed Airline Reservation System (PARS), respectively. Soon, travel agents began pushing for a system that could automate their side of the process by accessing the various ARSes directly to make reservations. Fearful this would place too much power in the hands of agents, American Airlines executive
Robert Crandall proposed creating an industry-wide computer reservation system to be a central clearing house for U.S. travel; other airlines demurred, citing fear that
United States antitrust law may have been breached.
Travel agent access
In 1976, United Airlines began offering its Apollo system to travel agents; while it would not allow the agents to book tickets on United's competitors, the marketing value of the convenient terminal proved indispensable. SABRE, PARS, and DATAS were soon released to travel agents as well. Following
airline deregulation in 1978, an efficient CRS proved particularly important; by some counts,
Texas Air executive
Frank Lorenzo purchased money-losing
Eastern Air Lines specifically to gain control of its SystemOne CRS.Also in 1976
Videcom international with
British Airways,
British Caledonian and CCL launched
Travicom, the world's first multi-access reservations system (wholly based on Videcom technology), forming a network providing distribution for initially two and subsequently 49 subscribing international airlines (including British Airways, British Caledonian,
Trans World Airlines,
Pan Am,
Qantas,
Singapore Airlines,
Air France,
Lufthansa,
Scandinavian Airlines System,
Air Canada,
KLM,
Alitalia,
Cathay Pacific and
Japan Airlines) to thousands of travel agents in the UK. It allowed agents and airlines to communicate via a common distribution language and network, handling 97% of UK airline business trade bookings by 1987. The system went on to be replicated by Videcom in other areas of the world including the Middle East (DMARS), New Zealand, Kuwait (KMARS), Ireland, Caribbean, United States and Hong Kong. Travicom was a trading name for Travel Automation Services Ltd. When British Airways (who by then owned 100% of Travel Automation Services Ltd) chose to participate in the development of the Galileo system Travicom changed its trading name to Galileo UK and a migration process was put in place to move agencies from Travicom to Galileo.European airlines also began to invest in the field in the 1980s initially by deploying their own reservation systems in their homeland, propelled by growth in demand for travel as well as technological advances which allowed GDSes to offer ever-increasing services and searching power. In 1987, a consortium led by Air France and West Germany's Lufthansa developed
Amadeus, modeled on SystemOne. Amadeus Global Travel Distribution was launched in 1992. In 1990, Delta,
Northwest Airlines, and Trans World Airlines formed
Worldspan, and in 1993, another consortium (including British Airways, KLM, and
United Airlines, among others) formed the competing company
Galileo GDS based on Apollo. Numerous smaller companies such as KIU have also formed, aimed at niche markets not catered for by the four largest networks, including the
low-cost carrier segment, and small and medium size domestic and regional airlines.
Trends
For many years,
global distribution systems (GDSs) have had a dominant position in the travel industry. To bypass the GDSs, and avoid high GDS fees, airlines have started to sell flights directly through their websites.Strauss, Michael (2010),
Value Creation in Travel Distribution Another way to bypass the GDSs is direct connection to travel agencies, such as that of
