Fare Calendar
Fare Calendar is a free Flexbook tool to find the cheapest day to fly between any two cities. Pick a flexible date window and see live fares day by day — change anything and the answer updates live.
How it works
- Pick the two cities you want to fly between.
- Choose a window: a preset such as This month or Next 90 days, or your own date range.
- Compare fares across the window, find the single cheapest day, then book that flight in one tap.
Who it is for
Fare Calendar is for travellers who know the route but can move their dates — a few days earlier or later can change the fare a lot. If you know the exact date already, use Flight Search; if you are open on the destination too, Budget Planner can build the whole trip.
Tips for a cheaper trip
- Midweek flights are often cheaper than Fridays and Sundays, and the calendar makes the difference easy to spot.
- Use a wide window such as Next 90 days when price matters more than the exact date.
- Once you have the date, open Trip Builder from your destination to add more stops.
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.
