What Is a Global Distribution System (GDS)? A Complete Guide for Travel Agents
A Global Distribution System is the computerised network travel agents use to book flights, hotels, car rentals, and other travel services in real time. Every airline reservation, e-ticket issuance, and refund calculation flows through one of the three major platforms: Amadeus, Galileo (Travelport), or Sabre.
If you work in travel — whether you handle leisure bookings, corporate travel, or airline ticketing — fluency in a GDS is not optional. It is the core skill that separates hobby travellers from professional agents. That is why we built a free online simulator: to give every aspiring travel professional a safe, realistic place to practice real commands without the pressure of a live reservation system.
Why Practice Beats Theory in GDS Training
You can read every command reference in the world and still freeze the first time a client asks for a reissue. Commands like FQD, TWD, FXP, and QEB only become second nature when you use them repeatedly in realistic scenarios. Our simulator is built around that idea — every exercise mirrors a real workflow you will face in an agency.
- Build bookings from scratch with passengers, segments, contacts, and ticketing arrangements.
- Issue and void tickets to understand the exact sequence and required elements.
- Process reissues and refunds with real fare rules and penalty structures.
- Handle queues the way live ticketing offices do — from placement to processing.
- Master NDC workflows — the modern standard for airline distribution.
Who Is the Free GDS Simulator For?
Our platform serves three types of users. Beginners use it to build confidence before their first agency job. Ticketing professionals sharpen specific workflows — refunds, reissues, exchanges, ADMs. Agencies onboard new staff without risking live PNRs or paying for expensive simulation licenses.
To compare the three platforms before you start, read our guide on Amadeus vs Sabre vs Galileo — which GDS to learn first, or dive straight into our Amadeus commands reference. You can also explore how airlines handle EMD service issuance and manual refunds across all three systems.

Quick answers about the free online simulator, the Amadeus Course, Galileo Course, Sabre Course, and the tools we offer.
Is the GDS simulator really free?
Yes — 100% free, forever. There are no hidden fees, no premium tiers, and no credit card required. Create an account and you will have instant access to the terminal simulator, the Amadeus Course, Galileo Course, Sabre Course, and every tool on the site.
Which GDS systems are supported?
The platform supports Amadeus (1A), Galileo (1G), and Sabre (1S) — plus NDC workflows through a dedicated interface. You can read the full NDC vs GDS comparison to understand how both standards coexist.
Do I need any prior experience to use the free GDS simulator?
No. It is built for beginners and professionals alike. If you are new to travel, start with the Amadeus Course, Galileo Course, and Sabre Course and basic command references. If you are already working in an agency, jump straight into advanced workflows and refund calculations.
Does the simulator connect to a live GDS or airline inventory?
No. It is a standalone educational environment. It never connects to Amadeus, Travelport, Sabre, or any live airline system. You practice real commands without any risk to real bookings or PNRs.
Can I use GDSHelper without learning the commands first?
We recommend against it. GDSHelper is a productivity tool for professionals who already understand reissue and refund calculations. If you cannot calculate a refund manually, you will not be able to interpret GDSHelper’s results correctly — so start with the free simulator and command references first.
Do you offer GDS certification exams?
Yes. We offer free certification exams for both Amadeus Basics and Amadeus Advanced, plus a Galileo Advanced exam. Each exam draws from a large question bank and issues a verifiable certificate on completion.
