Travel agents reach GDS content in four ways: through a host agency, through a consolidator that tickets for them, through their own IATA or ARC accreditation and a GDS contract, or through a travel API aggregator. Most leisure agents never need direct access. An agency that wants to sell online needs an API, not a terminal.

This guide is for agency owners and managers deciding how to get GDS content, and for the people who build their booking tools. It explains who actually needs a GDS, the four routes in, what each one asks of you and costs, how to choose between the GDS networks, and the questions to settle before you sign. If you want the basics first, read our guide to what a GDS is. The outside facts come from IATA and from Fora, a host agency; the Tripgic details come from our GDS page and pricing page. All were read on 6 October 2026.

Do You Need a GDS at All?

Start with this question, because the honest answer is often no. A GDS (global distribution system) is the network that connects travel sellers to airline, hotel and car inventory in real time. The three big ones are Amadeus, Sabre and Travelport. They are fast and powerful for air, and they are also complex, contract-based and built for professionals who book every day.

Whether that is worth it depends on what you sell and how you sell it.

Your business Do you need GDS access? Why
Leisure agent, mostly hotels, cruises and tours Rarely Supplier sites and your host’s tools cover it
Agent under a host agency Through the host, if at all The host owns the GDS contract
Agency with its own ticketing Yes A GDS is the working tool for issuing and changing tickets
Corporate travel agency or TMC Yes Complex itineraries, fare rules and frequent changes
Agency or OTA selling online Yes, through an API Travellers book on a website, not in a terminal

Fora, a host agency, puts it plainly: most leisure advisors do not meet the volume or complexity that makes direct GDS access worthwhile. The agents who do need one book a lot of air, handle complex or corporate trips, or run their own ticketing.

The Four Ways a Travel Agency Gets GDS Content

Once you know you need GDS content, there are four routes. They differ in what you must have first, how long they take and how much control you get.

Route You need Time Ticketed by Best for
1. Host agency An agreement with a host Days to weeks The host New and independent agents
2. Consolidator An account with a consolidator Days to weeks The consolidator Agencies that sell air but are not accredited
3. Accreditation + GDS contract IATA or ARC accreditation, then a contract with a GDS Months Your agency Established agencies with real air volume
4. Travel API aggregator A developer or tech partner, and one API contract Days to weeks to connect Depends on the provider: ask Agencies and OTAs that sell online

The routes are not exclusive. Many agencies combine them: a host agency for most bookings and a consolidator for special fares, or a GDS terminal for the agents and an API for the website. The sections below explain each route, what it costs and where it fails.

Route 1: Work Under a Host Agency

A host agency is an established, accredited agency that independent agents join. The agent books under the host’s accreditation and supplier agreements, and the host takes a share of the commission or charges a fee.

For GDS access, this is the simplest route in. Some hosts give direct GDS access to agents who meet experience requirements, but the host still owns the business relationship with the GDS. Others give agents their own flight booking tools that run on a GDS behind the scenes, so the agent never needs to learn GDS commands at all. Fora describes its own setup this way: its advisors book air through its flight tools and flight suppliers, without direct GDS access.

What it costs: whatever the host charges, usually as a commission split, a monthly fee or both. Any GDS fees are bundled into that relationship.

Where it falls short: you work inside the host’s rules, systems and supplier deals. You cannot build your own booking website on the host’s GDS contract, and you do not own the relationship with the GDS or the airlines. For a growing agency that wants its own brand online, this becomes a ceiling.

Route 2: Buy Through a Consolidator

A consolidator holds agreements with airlines and sells their fares to other agencies, often at net rates that a small agency could not negotiate alone. It issues the ticket under its own accreditation, so the agency selling the trip does not need its own IATA number.

This is how many small and mid-sized agencies sell international air. The agency searches the consolidator’s fares, books, and the consolidator tickets and handles much of the servicing. Our guide to the flight consolidator explains how consolidators work and how to check that one is legitimate.

What it costs: the consolidator earns on the gap between its net fare and the price it sells at, sometimes plus a service fee per ticket.

Where it falls short: your content is whatever that consolidator has. Fares outside its agreements, low-cost carriers and some NDC offers may be missing. You also depend on its speed for changes and refunds, which matters most when a traveller’s plans change on the day of travel.

Route 3: Get Accredited and Sign Your Own GDS Contract

This is the full-control route. Your agency gets accredited to issue tickets, then signs a contract directly with Amadeus, Sabre or Travelport.

Accreditation first. IATA accreditation gives an agency a unique code that airlines recognise, a single Sales Agency Agreement that lets it sell tickets for many airlines, and settlement through the Billing and Settlement Plan (BSP), which handles invoicing and payment between agents and airlines. IATA offers several models. GoLite is the entry option: a simpler process with no minimum financial guarantee to issue tickets. IATA charges a single annual fee, with no transaction costs on top. Agencies in the USA apply through IATAN instead and issue tickets through ARC, and the local requirements differ by country, so check IATA’s country checklists before you plan around a timeline.

Then the GDS contract. GDS providers partner with accredited travel businesses. There is no public price list: each contract is negotiated, and Fora describes the usual shape as a monthly access fee, a charge for each segment booked and productivity minimums. Your agents then work in the GDS’s own booking desktop, which takes training to use quickly.

Where it falls short: it is the slowest and heaviest route, and the minimums assume steady volume. It also gives you a terminal for your agents, not a booking website. Selling online on top of a direct GDS contract means a second project: an API integration, which takes 6–12 months per GDS when built directly.

Route 4: Connect Through a Travel API Aggregator

A travel API aggregator connects to the GDS networks once, and to NDC airlines and low-cost carriers as well, and gives you one API that returns all of it in a single format. You do not sign a contract with each GDS, and you do not run a separate certification for each one.

This route is for agencies that sell online: a booking website, an app, a B2B portal for other agents, or a mid-office tool. It is not a replacement for an agent’s terminal. You need a developer, or a tech partner who builds the front end, because an API returns data, not screens.

What it costs: it depends on the provider. Common models are a setup or activation fee, a fee per booking, a percentage of the fare, or a monthly subscription. Ask whether the fee is flat or grows with the fare, because that decides your margin on expensive tickets. Our guide to GDS API cost breaks down what a direct GDS connection costs for comparison.

Where it falls short: you rely on the provider for content and uptime, so test real searches for your own routes before you commit. And ask the question this guide keeps coming back to: who issues the ticket, and under whose accreditation? The answer differs from provider to provider, and it decides whether you need your own IATA number.

Which GDS Is Best for Travel Agents?

There is no single best GDS for every agency, and any list that names one is answering a different question. The three networks overlap heavily in airline content. What separates them for a given agency is more practical:

Question Why it decides
Which airlines and markets do you sell most? Each GDS is stronger in some regions and with some carriers. Test your top routes
Which GDS does your host or consolidator use? If you start with one, staying on the same system avoids retraining
What training can your team get? GDS work is command-driven. A system your agents already know is faster on day one
What do the contract terms say? Monthly fees, segment charges and minimums differ by contract, not by brand alone
Do you need NDC and low-cost carriers too? Much of that content sits outside a classic GDS connection

People also ask how Amadeus compares with Galileo. Galileo is one of three systems Travelport operates, next to Apollo and Worldspan, so the real comparison is Amadeus against Travelport. For the differences in reach, cost and technology between the three networks, see our comparison of Amadeus vs Sabre vs Travelport.

What GDS Access Costs a Travel Agency

The cost depends far more on the route than on the GDS brand. A direct contract has no list price, while the other routes fold the GDS cost into someone else’s fee.

Route How you pay What to watch
Host agency Commission split, monthly fee, or both Whether GDS access costs extra on top
Consolidator Margin on net fares, sometimes a ticket fee How fares compare with what you could get elsewhere
Accreditation + GDS contract Accreditation fee, then monthly access, segment charges and minimums Whether your volume meets the minimums every month
Travel API aggregator Setup fee plus a per-booking fee, a percentage or a subscription Whether the fee is flat or grows with the fare

Two costs are easy to miss on every route. The first is people: GDS training for agents, or developer time for an API. The second is servicing. Changes, refunds and voids take staff time, and a route that makes them slow costs you more than any monthly fee.

Is the GDS Still Relevant in 2026?

Yes, but it is no longer the whole picture. The GDS is still where most agencies book and service complex air itineraries, corporate travel and multi-airline trips. Two things have changed around it.

First, airlines now sell more of their best content through NDC, IATA’s standard for selling directly with branded fares and richer offers. Some of those offers do not reach a classic GDS connection in the same form. Our guide to NDC vs GDS explains the difference. Second, many low-cost carriers sell little or nothing through a GDS at all.

Developer access has also narrowed. Amadeus closed its Self-Service developer portal on 17 July 2026, leaving enterprise contracts as the direct route. Our Amadeus Self-Service migration guide covers what that means for teams that built on it.

So for an agency selling online, the question is not “GDS or not”. It is which mix of GDS, NDC and low-cost content your customers need, and how you get it without managing every connection yourself.

How Tripgic Fits

Tripgic is a travel API aggregator, so it serves route 4. It is built for agencies, OTAs and travel platforms that sell online, not as a terminal for agents booking by hand.

What you get Detail
Three GDS networks, one integration Amadeus, Sabre and Travelport through one API, with one commercial relationship instead of a contract per GDS
More than GDS content NDC results blended into the same search, plus 67 low-cost carriers and 700+ airline connections in total
One format Normalized JSON, whatever the source GDS returns, with the same flight from two networks shown once
Time to live Days rather than the 6–12 months a direct GDS integration takes; activations for live use usually take 3–5 business days
Pricing model A one-time activation, then a flat fee per transaction on top of the supplier’s net fare, never a percentage. Current figures are on the pricing page

Getting started follows one flow: book a short call, register, and receive free sandbox credentials before you pay anything. You can then test real searches on your own routes. On that call, ask how ticketing works for your agency and whether you need your own accreditation. It is the same question we suggest you ask every provider.

A Checklist Before You Choose a Route

Whichever route you pick, get these answers in writing before you sign. They are the questions agencies most often wish they had asked first.

  • Who issues the ticket, and under whose accreditation? This decides whether you need your own IATA or ARC number.
  • Which content do I actually get? Name the GDS networks, the NDC airlines and the low-cost carriers. A large airline count means little if your top routes are thin.
  • How are changes, refunds and voids handled? Ask who does the work, how fast, and what it costs per case.
  • What are the minimums? Monthly fees, segment minimums or booking minimums, and what happens in a quiet month.
  • Is the fee flat or a percentage? A percentage grows with every expensive fare. A flat fee does not.
  • Can I sell online with it? A terminal serves your agents. A website or app needs an API.
  • How long is the contract, and how do I leave? A route that is hard to exit is hard to fix later.

Final Thoughts

A GDS is a tool for professionals who book a lot of complex air. Most agents reach it through someone else: a host agency, a consolidator or a technology partner. Only agencies with real ticketing volume need their own accreditation and contract.

If your agency wants to sell online, start from the other end. Decide what your travellers need to book, then pick the route that gets that content onto your website fastest, with a fee you can build a margin on. For most new online agencies, that is one API rather than three GDS contracts. To understand the aggregator model in more depth, read what a travel API aggregator is.
