Soon, you will also be able to sell paid extras, like baggages and seat selection, through the Duffel API.

How does the Duffel API compare to Air Transat's API?

The Air Transat API offers similar functionality to Duffel, but only allows you to access content from Air Transat. If you want to offer content from other airlines, you would then need to integrate each individual airline's API, a process that is costly and time consuming. With Duffel, you integrate once, and get access to a network of 300+ of the world's leading airlines with just a single integration.

Duffel was also built with the developer in mind and offers simple, composable APIs, comprehensive documentation, and a robust testing environment. This means an integration takes minutes, not months. Check out our API Documentation here.
