What Is GDS? A Beginner's Guide

Learn what a Global Distribution System (GDS) is, how travel agents use it, and why the AYAZGDS simulator is a safe way to practice GDS commands.

A Global Distribution System (GDS) is a computerized network that connects travel service providers — such as airlines, hotels, and car rental companies — with travel agencies and booking platforms. For travel agents, the GDS is the main tool used to search availability, build itineraries, create PNRs, price tickets, and issue tickets.

Why GDS Skills Matter

Travel agencies still rely on GDS-trained staff to handle complex bookings, fare rules, exchanges, and refunds. Knowing the command workflow gives you an advantage when applying for ticketing roles.

Common GDS Commands

Here are a few commands you will see in training:

RT              Redisplay a PNR
AN15AUGDACDXB   Availability search
SS9Y1           Sell a class
FXR             Fare calculation
FXX             Issue ticket
