Cheap flights from London to Trondheim

May is the cheapest month to fly from London to Trondheim, and the price calendar lists fares from September through July, so you can compare most of the year before you commit. August is the gap in that calendar. Summer departures in June and July fall in the school-holiday window, when fares in both countries rise, while spring and autumn are calmer. Midweek flights and less convenient connection times usually cost less than Friday or Sunday departures. If your plans are flexible, watch the calendar for a few weeks and book once a fare you like appears.

Ten carriers appear on this route: Norwegian, Norwegian International, Wizz Air, KLM Cityhopper, British Airways, KLM Royal Dutch Airlines, German Airways, Finnair, Scandinavian Airlines and LOT Polish Airlines. Norwegian and Wizz Air are the low-cost options, so expect a bare fare with bags and seat selection costing extra. The rest are full-service, which usually means a checked bag and something to eat on the longer legs. Nothing flies nonstop, so every itinerary connects, typically through the home hub of the airline you choose. That is where the real difference shows: a tight transfer is quicker but leaves no room for a delay, while a longer layover is easier on the nerves.

Trondheim is served by one airport, Trondheim Airport, and it sits outside the city rather than in the middle of it. Airport buses and taxis meet arrivals and run into the centre, so the transfer is straightforward once you have cleared the terminal. If you land late in the evening, check the last bus before you book, because the frequency drops off. Give yourself time between a connecting flight and your onward transport, and keep your cabin bag with you if the layover is short. In winter, allow extra room in your plans, as weather in Norway can slow both flights and road transfers.

Country facts: Wikidata

• Check which London airport your fare leaves from, since Heathrow, Gatwick, Stansted, Luton and London City are all on this route.
• Look at the baggage rules on Norwegian and Wizz Air, where a cabin bag may be all that is included.
• Confirm whether your connection is on one ticket or two, because separate tickets leave you responsible for a missed leg.
• Check that your passport or ID is valid for entry to Norway before you pay.
• Compare dates on the price calendar rather than a single day, as May is the cheapest month.
• Leave a comfortable gap between flights, since a tight transfer through a hub leaves no room for delay.
