About the Company

Duffel

APIs for searching, booking flights

Duffel provides a suite of APIs that let travel sellers search, book, and manage flights. It works by offering developer-friendly endpoints that connect to many airlines, support changes and cancellations, and enable add-ons like paid seats, baggage, and pay-later options. It also supplies extensive documentation, client libraries (Node.js, Python, Ruby), and prebuilt UI components to simplify integration and product design. Duffel differentiates itself by focusing on a scalable, API-first platform that lets both traditional travel agencies and non-traditional sellers easily embed flight functionality into their own systems, with revenue tied to clients’ usage. The company’s goal is to help travel sellers diversify revenue streams and improve the end-to-end customer experience through a flexible, integrable flight API platform.
