What features are available on SunExpress through the Duffel API?

With Duffel, you can search, book, and manage flights. We also have a changes API coming soon that will enable you to change your SunExpress flights.

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 SunExpress's API?

The SunExpress API offers similar functionality to Duffel, but only allows you to access content from SunExpress. 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.
