Duffel

Duffel provides a software platform and API for selling flights, stays and travel extras. Its product suite covers flight search, booking, ancillaries (baggage and seat selection), order management and managed content, plus stays inventory with commission. Client libraries are offered for Node.js, Python and Ruby.

The company sells to businesses of all sizes, from startups to large enterprises, including challenger banks and spend management platforms that embed travel into their own products. Pricing is pay-as-you-go with per-order, percentage-of-order and per-ancillary fees, an excess search fee above a 1500:1 search-to-book ratio, and bespoke enterprise pricing.

Duffel says it was founded in 2017 and is backed by investors, with offices in London and New York indicated by its job listings. Its open roles include engineering, product, customer success, legal, operations and recruitment.
