Cheap flights from London to Copenhagen

February is the cheapest month on this route, and the quiet weeks after the New Year holidays keep fares down. Summer, from June through August, is the busiest stretch and fares climb with demand. Spring and autumn sit in between, with decent weather and lighter crowds. Midweek departures, especially Tuesday and Wednesday, usually cost less than Friday or Sunday flights. Watch school holidays in both countries, plus Christmas and New Year, when seats sell fast. Book a few weeks ahead for summer, and closer in for winter, when seats are easier to find.

Several carriers fly London to Copenhagen. Ryanair and its UK arm, Easyjet and EasyJet Europe, and Wizz Air are the low-cost names, usually with lower headline fares and more extras priced separately. Scandinavian Airlines, Norwegian and Norwegian International, and Malta Airlines are the full-service options, where a fare tends to include more as standard. You may also see Mokulele Flight Service listed. Direct flights exist, so you can skip a connection, but read what each fare covers before you pay, because baggage and seat rules differ sharply between carriers.

Copenhagen has one main airport, Kastrup, and it sits close to the city, so a short metro or train ride gets you to the centre without much fuss. Trains also run across the Øresund bridge to Malmö in Sweden, so check you are on the right service if you are heading into Copenhagen itself. The arrivals hall is compact and easy to navigate, with signage in English. Have your passport and any entry documents for Denmark ready, and note which terminal your return flight leaves from before you head back.
