A Global Distribution System (GDS) is a worldwide computer network that connects travel agents to airlines, hotels and other travel providers, letting them search availability, book and issue tickets in real time.
What does a GDS do?
A GDS aggregates inventory and fares from many airlines into a single interface. Instead of contacting each airline separately, an agent can search schedules, compare fares, sell seats, build a passenger record (PNR) and issue tickets — all from one terminal.
How agents use a GDS
GDS systems are command-driven. Agents type short, cryptic entries to perform actions, for example:
SS9Y1 (sell a seat)
FXR (price the itinerary)
Learning these commands is the core skill of professional air ticketing. See our list of top GDS commands for beginners.
Why practice on a simulator?
Live GDS access is restricted and mistakes can be costly. A GDS training simulator lets you learn the commands safely. When you're ready, read why practical GDS training matters.
