Cheap flights from London to Turku

May is the cheapest month on this route, and the price calendar here covers September through May, so you can weigh autumn, winter and spring before you commit. Late autumn and the deep winter months are quiet and often good value, while the weeks around Christmas and Finnish Midsummer fill up early and cost more. Midweek departures, especially Tuesday and Wednesday, usually undercut Friday and Sunday flights. Book a few weeks ahead for winter travel, and earlier for spring if your dates are fixed, because the connections sell out before the fare itself rises.

Nothing on this route is nonstop, so every itinerary pairs two legs, and often two airlines. Wizz Air and Air Baltic sell the low-cost version: a seat, a small cabin bag, and a fee for anything else, including checked luggage and seat selection. Scandinavian Airlines, Finnair, KLM Cityhopper, LOT Polish Airlines, Swiss, Austrian, Brussels Airlines and German Airways are the full-service options, where a checked bag and a snack are usually part of the ticket and the connection is protected on one booking. If you mix carriers on separate tickets, the second leg is not protected when the first one runs late.

Turku Airport is the only airport serving the city, so there is no second option to compare and no risk of landing at the wrong one. It sits outside the centre and the transfer in is short, by local bus or taxi. Because every flight from London involves a connection, your bags are usually checked through to Turku when the whole trip is on one ticket; on separate tickets you collect them at the transfer airport and check in again. Allow extra time on the way back, since the airport is small and the check-in desk closes well before departure.

Country facts: Wikidata

• Check which London airport your ticket uses, because Heathrow, Gatwick, Stansted, Luton and London City are not interchangeable.
• Confirm what the low-cost fare includes, since a cabin bag only is standard on Wizz Air and Air Baltic.
• If your connection sits on two separate tickets, leave a long gap and be ready to rebook at your own cost if the first flight is late.
• Carry a valid passport or identity card for Finland and check the entry rules that apply to your nationality.
• Compare May against the winter months on the price calendar, because May is the cheapest month here.
• Book the whole trip on one ticket where you can, so a missed connection is the airline's problem, not yours.
