Travel & Booking Platform
A travel booking site with flight and hotel search, secure payments, and an itinerary manager.
The Challenge
The client needed to aggregate multiple travel suppliers into one fast, reliable booking experience.
Our Solution
We integrated supplier APIs into a unified search, with real-time pricing, secure checkout, and automated booking confirmations.
How we approach this kind of build
Aggregating suppliers means your search is only as fast as the slowest API you call. We query suppliers in parallel with a hard time budget and return partial results rather than making the user wait for a straggler, then fill in late arrivals progressively. Availability and pricing are cached briefly — long enough to make browsing fast, short enough to keep quotes honest.
The hard problem is that a price shown is not a price guaranteed. Supplier availability changes between search and checkout, so the booking flow re-validates before payment and handles the price-changed and no-longer-available cases as designed states with clear messaging, rather than as errors. Getting this wrong is the main source of abandoned bookings and support tickets.
Booking itself has to be resilient: payment captured but supplier confirmation failed is the worst possible outcome, so the flow is built around idempotent operations with compensating actions and an operations queue for anything that lands in an inconsistent state. Confirmations, itineraries, and changes are automated end to end.
