How Flexbook works

How Flexbook works: most flight sites lock you into a round trip, while Flexbook builds cheaper multi-city trips. Pick a starting airport and a date, see the cheapest flight out that day, and once you land, search the next cheapest flight from there.

Build your own multi-city trip one stop at a time, then buy it all together when you are ready. No login required.

Three steps

• Start with Trip Builder — most people begin here. The other tools are shortcuts for when you already know the route, the dates or the budget.
• The price you see is the price you pay: every option is a real fare we just pulled.
• Add stops, adjust dates, share the link, and book when you are happy with the trip.

Why one-way hops are cheaper

Low-cost and regional airlines price each one-way flight on its own, so the cheapest way to see several cities is often a chain of short one-way fares rather than a return ticket plus extra legs. Flexbook searches those one-way fares from wherever you are and shows the cheapest options first. You are never locked into a fixed route either: if a city turns out expensive, pick a different next stop.

Sharing and saving trips

Every trip lives in its link. Copy the URL to share a plan with friends, or open it later to pick up where you left off. A free account lets you save trips to your profile too, but no tool requires one.

How booking works

Flexbook finds and plans the trip; bookings are completed on Kiwi.com, our booking partner. When you press Book, you go to Kiwi.com with your flights already selected and pay there, at the price Flexbook showed you. Flexbook adds no markup and no booking fee.
