Background

• Airlines need to maintain multiple types of information Route information: Covers the destinations served

by the airline Aircraft information: Information on the aircrafts

used by the airline Schedule information: Covers information on days

and times on which the flights operated by the airline are scheduled to run

Fare information: Prices for various flights Reservation information: Passenger and cargo

reservations, including information on passenger tickets

Background (continued…)

• Prior to 1950 all this information was published by airlines in large books, with separate books for each type of information

• Travel agents had a really tough time looking through multiple books for booking tickets that covered multiple airlines

• It was impossible to get a real-time view of the inventory (available seats on a flight) since airlines could synchronize data from multiple locations only once a day

• In order to make a booking, a customer would call up a travel agent, providing them details of their itinerary

• Travel agent would first look up airlines, flights and schedules matching the customer’s itinerary

• Customer would then call up individual airlines to check seat availability

• Once seat availability was confirmed, travel agent would look up the price appropriate for the flights selected and inform the customer

• Upon confirmation from the customer, travel agent would call the airlines back to reserve the seats

• In 1950 American Airlines decided to set up a computerized system that would allow real-time access to all its data across all its offices and travel agents

• As a result, Semi-Automated Business Research Environment, or SABRE was born in 1964. It was the first computerized airline system (CRS) in the world

• SABRE was developed as a joint effort between IBM and American Airlines

• When created, SABRE ran on two IBM 7090 mainframes. The system was upgraded to IBM S/360 in 1972

• In the 1970s and 80s multiple CRSs came up in North America

• The first non-North American CRS was developed jointly by Air France, Lufthansa, Iberia and SAS in 1987. It was named Amadeus

Functions provided by a CRS

• A CRS typically provides the following functions Flight schedule information: Days and times for flights

operated by the airline Availability information: Seat availability on a flight by

service class, i.e. Economy, Business or First class Fare quotes: A consolidated fare for an itinerary based

on flight, day, time, service class and passenger types chosen

Reservation information: Seat bookings Ticketing information: Generating and storing tickets Refunds and cancellations: Cancellation of existing

reservations and tickets

History behind Global Distribution Systems

• Although the CRSs simplified the task of maintaining airline data, they brought in new problems In order to handle increasing passenger traffic, large

computer systems were required for CRSs. This created a cost burden for airlines, especially the smaller ones which did not have enough money to spend on expensive mainframe technology

CRSs were airline specific. This required travel agencies who wanted to sell tickets for multiple airlines to have individual connections to each airline separately

Availability and fare searches across airlines was not possible since each airline had its own CRS. Since most passengers were interested in purchasing the cheapest fare rather than a specific airline, travel agents had to spend inordinate amount of time to determine cheapest fares across airlines

The birth of Global Distribution Systems

• CRSs recognized the need to host data for more than one airline in order to bring efficiencies to a growing airline industry

• Thus, CRSs transformed from being single airline reservation systems to multi airline distribution systems (GDSs)

• These GDSs also decided to share data among each other to bring in additional efficiencies

Problems before advent of GDSs

• Travel agents required individual connections to airlines

• If two or more airlines used different mainframe systems, travel agents had to use and be trained on different mainframe clients

• Inability to perform direct searches across airline systems

• Combining airline inventories a tedious process because inventory searches and reservations had to be performed in individual airline CRSs separately

Advantages of a GDS

• Simplified access to possibly all airlines, through a single interface

• Ability to connect to multiple airlines either through legacy mainframe clients or modern PC based clients

• Less maintenance and up-keep overhead

• Ability to combine airline inventories

How GDSs have evolved

• Due to airline CRSs being based on mainframes, GDSs have been based on mainframes as well

• Over the last few decades, GDSs have started providing direct connectivity from non-mainframe clients such as PCs

• GDSs have also started leasing hosting space (hardware, software and connectivity) to airlines which do not want to create and host their own CRSs

• The advent of Internet has seen GDSs offer innovative products suited for accessing airline information over the Internet

How GDSs have evolved (continued…)

• GDSs now provide access to non-air products as well: Car rentals

Hotel booking

Packaged holidays

Cruises and ships

Railways

Local road transport: bus, tram, taxi

Summary

• Airlines need to store multiple types of information such as routes, schedule, fares and reservations

• Travel agents need access to multiple pieces of information before making a reservation

• Before 1950 airline information was stored, distributed and accessed through non-electronic media
