Side-by-side comparison of AI visibility scores, market position, and capabilities
Airline booking API enabling businesses to embed direct flight search, booking, and ancillary sales into their own products with modern developer tooling.
About
Duffel is a London-based travel technology company that provides a developer-friendly API for embedding airline flight search, booking, and ancillary product sales — such as seat selection, baggage, and cancellation protection — directly into any application or website without requiring GDS contracts or legacy ATPCO certification. The platform connects directly to airline reservation systems via NDC (New Distribution Capability) and traditional GDS channels, enabling businesses to access live flight inventory and fares with a single modern REST API. Duffel's comprehensive SDK for JavaScript, Python, Ruby, and PHP reduces the engineering time required to build flight booking capabilities from months to days, lowering the barrier for fintech companies, neobanks, super-apps, and travel startups to offer flight booking as part of a broader product. The platform handles payment processing, ticketing, and post-booking management including cancellations and exchanges, abstracting the complexity of airline commerce rules. Duffel makes money by taking a fee per booking rather than charging seat or subscription fees. Founded in 2017 by former Deliveroo and Google engineers, Duffel raised over $100M from investors including Benchmark, Index Ventures, and Avid Ventures.
