Detour

Sometimes the cheaper flight isn't the direct one — it's two flights and a free city in between.

Mobile Amadeus API Route Opt. Real-time
FIG. 01 — Demo A search, a smarter route, a cheaper trip with extra cities along the way.

Booking flights across Asia, you keep running into the same trap: the direct route is rarely the cheapest one. Skiplagging, stopover hacks, and multi-city tricks save real money — but figuring them out by hand is exhausting.

Detour rethinks budget travel by treating multi-city stopovers as a feature, not a workaround. The app pulls real-time fares from the Amadeus API, generates candidate routes that pass through nearby cities, and ranks them against direct flights on price, layover convenience, and total time.

The result: trips that sometimes cost less than the direct flight — and let you actually visit a second city for free along the way.

Under the hood

What makes it actually work.

/ 01

Real-time fare data

Amadeus API pulls live flight offers across hundreds of city pairs — not cached aggregator data that's already wrong by the time you book.

/ 02

Smarter route discovery

For every direct route, the app generates candidate detour cities, prices each leg, and surfaces only the combinations that beat the direct flight.

/ 03

Built for trade-offs

Side-by-side comparison weighs cost against layover length and total travel time, so users pick the route that fits their priorities — not just the cheapest one.
