Flight Search
Flight Search is a free Flexbook tool that finds the cheapest one-way, return or multi-city flights. Pick origin, destination and dates to get live fares, or plan a full multi-city itinerary in one form.
How to use it
- Choose one-way, return or multi-city.
- Enter your airports or cities, dates and number of passengers.
- Compare live fares, sorted with the cheapest and simplest options first, then go straight to booking.
- Each result shows the number of stops and the flight times, so you can trade price against convenience.
Who it is for
Travellers who already know the route and want the cheapest live fare without creating an account. If you know the route but not the date, Fare Calendar finds the cheapest day; if you only know where you start, try Trip Builder. It is also the quickest way to check a single fare before committing to a bigger multi-stop plan.
Tips for a cheaper trip
- Check other airports in the same city or region — they can be much cheaper.
- When visiting more than one place, a multi-city search often beats two separate return tickets.
- Prices change often, so book once you see a fare you are happy with.
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.
