Context
Agencies and businesses booking travel were stuck between consumer sites and expensive legacy systems. They needed real-time availability across airlines, secure payment, and itinerary management inside a platform they controlled.
Constraints
Airline content had to be live, schedules, pricing, and status, from a single integration; payments had to run through encrypted, trusted gateways; travellers needed seat and amenity selection; and the agency back office needed automation, not more admin.
What we built
A booking platform integrated with the Duffel API: real-time flight search and comparison across multiple airlines, live pricing and flight status, secure booking and payment, itinerary management, seat and amenity selection, personalised traveller preferences, and administrative automation for the agency.
Architecture
Web platform with real-time connectivity to the Duffel API for multi-carrier content; payment gateway integration with encryption; itinerary and preference services; an administrative layer automating routine agency tasks.
Delivery
Discovery on the agency's markets and workflows; a written scope covering airline coverage and payment providers; design of the search-to-ticket journey; build against the live API with weekly demos; verification of pricing accuracy and payment flows; run with a demo environment for onboarding new agencies.
Outcomes
Agencies gain a branded, real-time booking platform with multi-airline reach, a streamlined booking process, and secure transactions, without building airline integrations themselves.
Carried forward
The right API partner turns a year of integration work into a product decision. We choose integrations for the breadth they give the client, not for how impressive the build looks.
