Flexbook tools

Flexbook tools are five free flight tools for multi-stop trips and multi-city travel. Pick one based on what you already know: the route, the dates, the budget, a list of cities — or only your home airport. Every tool uses live fares and works without an account.

Which tool should I use?

• Flight Search: you know where and when. Pick origin, destination and dates to get the cheapest live fares — one-way, return or multi-city.
• Trip Builder: you only know where you start. Pick the cheapest next flight, set your nights, repeat — up to 15 stops.
• Fare Calendar: you know the route but not the date. Pick two cities and a flexible window to find the single cheapest day to fly.
• Budget Planner: you know how much you can spend. Give a start, dates and a budget to get the cheapest multi-stop trip that fits, return flight included.
• Route Builder: you know the cities but not the order. Drop them in to get the cheapest order to fly them and the nights per city.

What every tool has in common

Fares are fetched live for each search rather than read from a cache, so the price you see is the price you can book. Trips are saved in the page link, which means you can bookmark a plan or send it to a friend without anyone signing up.

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.
