Cheap flights from London to Prague

February is the cheapest month on this route, and the price calendar shows how the rest of the year sits around it. Winter travel outside the Christmas and New Year window is usually the quietest stretch, while late spring and summer push fares up as both cities fill with visitors. Midweek departures tend to undercut Friday and Sunday, when weekend breaks and business travel overlap. Book a few weeks ahead for winter and further ahead for summer, when the cheap seats with the low-cost carriers go first.

The carriers listed for this route run from budget to full-service. Ryanair, Ryanair UK, Wizz Air UK, Wizz Air Malta, easyJet and easyJet Europe are the low-cost names: your fare buys a seat and a small cabin bag, and checked luggage, seat choice and food are add-ons. British Airways is the full-service option, with more folded into the ticket. Norwegian, Norwegian International and Mokulele Flight Service also appear in the mix, so read what each one includes rather than picking on headline price alone. Check whether your flight is direct or a connection, since a cheap fare through another hub can eat a day.

Prague has a single airport, Ruzyne, and it sits outside the city rather than beside it, so plan a transfer instead of a walk to your hotel. Buses and taxis are the usual ways into the centre, and ride-hailing apps work much as they do elsewhere. If you land late, sort out your onward journey before you book, because the cheapest tickets often arrive after dark. Ruzyne is the only airport serving the Czech capital, so every flight into Prague lands there and there is no second option to weigh up.

Country facts: Wikidata

• Check which London airport you fly from, because City, Gatwick, Heathrow, Luton and Stansted sit far apart and turning up at the wrong one is costly.
• Confirm what your low-cost fare includes, since Ryanair, Wizz Air and easyJet charge separately for checked bags and seat selection.
• Make sure any connecting itinerary is issued on one ticket, or a missed leg will not be protected.
• Check your passport and the entry rules for the Czech Republic well before departure.
• Compare February with the months on either side, because that is when fares on this route drop.
• Decide whether you need a bag in the hold before you compare prices, or the cheapest fare will not be the cheapest trip.
