Duffel

Duffel is a travel technology platform that provides APIs for businesses to search and book flights and stays, add travel extras such as seats and bags, charge customers, and manage orders. It is designed to help companies of different sizes sell travel without building the underlying infrastructure themselves, including access to airline content through Duffel's accreditation and ticketing authority.

The platform includes modules for flight search, booking, ancillaries, order management, and managed content, as well as a stays product with global inventory, loyalty benefits, and rich content. It offers client libraries for Node.js, Python, and Ruby, along with prebuilt components for seat selection and payments. The service runs on Google Cloud Platform and is PCI-DSS v4 Level 1 compliant, with encryption in transit and at rest, role-based access control, single sign-on, and regular penetration testing.

Duffel is aimed at startups, challenger banks, spend management platforms, and large enterprises that want to embed travel booking into their own products. It offers a pay-as-you-go plan with no upfront fees and email-based technical support, as well as an enterprise edition with bespoke pricing, volume discounts, dedicated technical support, and the option to use your own IATA or ARC accreditation. A free trial is available to get started.
