The Galileo API is a set of application programming interfaces provided by Galileo, a leading Global Distribution System (GDS) operated by Travelport. It enables travel companies to access and integrate a wide range of travel-related services into their websites, mobile apps, or booking engines.

At its core, the Galileo API allows developers to connect to a comprehensive global inventory of travel content — including flight availability, schedules, fares, bookings, hotel reservations, car rentals, rail, and more — all in real time. This empowers online travel agencies (OTAs), tour operators, travel startups, and other service providers to build scalable, automated, and feature-rich travel platforms.

The cost of integrating Galileo API in UK depends on several factors, such as the services you wish to integrate (flights, hotels, cars, etc.), your business model, and the expected booking volume. Travelport (Galileo's parent company) typically offers different pricing models, including setup fees, ongoing subscription charges, and per-transaction fees. For small or mid-sized travel agencies, Galileo may offer cost-effective plans or even limited free access through authorized distributors or aggregators to promote adoption.

For enterprise-level or full-service integrations, the costs are usually higher and require direct negotiation with Travelport or its certified GDS partners. These integrations may come with enhanced support, real-time data access, service-level agreements (SLAs), and full certification. The setup fees in such cases may include development, integration, and compliance, while ongoing fees often depend on API UKge or the volume of completed bookings.

Additionally, travel businesses should consider the internal development and maintenance costs of integrating Galileo APIs. Even with access, creating a fully functional booking engine or travel portal requires technical resources. This could involve hiring software developers or working with third-party travel tech companies. Overall, the total cost of Galileo API integration can vary significantly — from minimal for basic access to substantial for advanced, high-volume integrations — and is best confirmed by contacting a certified Galileo GDS provider or Travelport directly.

The demand for Galileo API Integration has grown rapidly due to increasing digital transformation in the travel industry. As travel agencies seek better customer experiences, streamlined operations, and competitive digital offerings, the shift toward B2C and B2B travel systems has become vital.

The travel software market is projected to grow from USD 10.05 billion in 2024 to USD 20.1 billion by 2032, exhibiting a compound annual growth rate (CAGR) of 9.04% during the forecast period (2024 - 2032). Additionally, the market size for Travel Industry Software was valued at USD 9.1 billion in 2023. ‘All-in-one-place’ online travel portal platforms have improved the user experiences to another level and that's why it's fueling the demand for b2b travel portal and travel portal software in UK.
