How it works

Tell ffly where you want to go. It works out the order, the dates and the flights.

  1. Pick your cities

    Where you start, up to 3 places to finish, and up to 8 cities to see. Mark each one a must or a maybe: a maybe is skipped when leaving it out makes the trip cheaper.

  2. Set dates and nights

    Choose your travel window and how many nights you want in each city.

  3. Choose what matters

    Best schedule, Balanced or Cheapest. Routes are ranked by what you pick.

  4. Get your routes

    ffly runs the search in the background and lets you know when your routes are ready.

What a good route gives back

Money, nights, hours and sleep. Free shows you the route and its total; ffly Pro shows every route in full, so you can see each of these for yourself.

  1. Money

    The cheapest trip, not the cheapest first flight.

    ffly prices whole routes, trying your cities in different orders across your dates, so a bargain first leg cannot lock you into an expensive rest of the trip.

  2. Hotel nights

    Fewer hotel nights you pay for but barely use.

    Every priority, even Cheapest, counts a midnight landing as the hotel night it costs you, so the nights you book are nights you actually sleep there.

  3. Time

    Hours of tab-hopping, done in minutes.

    Fares from Ryanair, Wizz Air, airBaltic, Volotea and more, between all your cities and across every day of your window, compared for you. One search can weigh more than a thousand of them.

  4. Sleep

    Fewer 3 a.m. alarms.

    A 6:05 departure means a 3:30 alarm. ffly favours routes without one, and shows the early starts and lost sleep on the routes that have them.

  5. Fit

    A schedule that fits how you travel.

    Best schedule, Balanced or Cheapest: routes are ranked by what you chose. There is no single right way to travel.

Best of 6 routes, flights total €129.62

A real search against live fares on 2 October 2026, starting in Warsaw and finishing in Warsaw or Vilnius. It shows what a result looks like, not a price or saving you will get: fares change constantly and your trip will differ. This is the Free view; ffly Pro adds the dates, flight times and booking links.
