Our Story

I still remember the knot in my stomach during my first week as a travel agent.

I had just started handling live bookings on Amadeus, and the sheer number of commands felt overwhelming. FQD, FXP, TWD — they all blurred together. One afternoon, I misquoted a change fee to a client because I forgot to check the historical issue date. That small mistake cost my agency money, and worse — it cost me a bit of the trust I was trying to build.

That frustration stuck with me. I realised that most training resources were either too theoretical, too expensive, or scattered across dozens of PDFs. So instead of just memorising commands, I started building tools to simplify my own daily workflow. Eventually, I asked myself: “Why not share these tools with other agents who are struggling the same way I did?”

That question gave birth to GDS Hub. It’s not just a blog or a command list — it’s a complete ecosystem where beginners can practise fearlessly, and professionals can save hours of manual work.

What is GDS? A Global Distribution System (GDS) is a computerised network used by travel agents to book flights, hotels, and other travel services. Amadeus, Galileo (Travelport), and Sabre are the three major GDS platforms. PNR (Passenger Name Record) is the unique record of a booking. Fare Basis is the code that defines the fare rules. Reissue refers to changing a ticket, and Refund is the cancellation and money return process.
