Flying from Copenhagen to London
The flight from Copenhagen Airport (CPH) to London covers roughly 608 miles across the North Sea and southern Scandinavia, making it one of the more comfortable short-haul routes in Europe. Block time is typically around 1 hour 45 minutes to 2 hours when you factor in realistic taxi and climb times, though published schedules often list it closer to 1 hour 50 minutes. It is genuinely one of those routes where you are barely at cruising altitude before the cabin crew are collecting cups.
What makes this route slightly more complicated than most is that London is served by five airports, and airlines operating cheap flights to London from Copenhagen use at least four of them. British Airways and SAS land at Heathrow (LHR), which is central to most business travellers' needs. Ryanair uses Stansted (STN), easyJet splits between Gatwick (LGW) and Luton (LTN), and Norwegian has used Gatwick. Always check which London airport you are actually flying into before booking — the price difference between a Ryanair fare to Stansted and a British Airways fare to Heathrow can look dramatic on paper but shrinks once you add a 50-minute train from Stansted into the total journey cost.
Airlines on This Route
This is a well-served route with genuine competition between full-service and budget carriers, which keeps fares relatively honest. British Airways operates the highest frequency with around 41 flights per week from CPH to LHR, typically using Terminal 5 at Heathrow. Scandinavian Airlines (SAS) runs approximately 32 weekly departures, also into Heathrow. These two carriers dominate the business travel market on the route and offer proper flexibility on ticket changes.
On the budget side, Ryanair operates around 22 weekly flights into Stansted, and easyJet connects Copenhagen with both Gatwick and Luton. Norwegian has historically offered competitive fares on this corridor, particularly into Gatwick, though their schedule changes frequently — always worth checking their current availability. Finnair also appears on the route on some booking platforms, sometimes as a codeshare. For pure price, Ryanair and easyJet consistently undercut the full-service carriers, but if you are connecting onward or need Heathrow specifically, SAS and British Airways are the practical choice.
Flight Prices: Copenhagen to London
Copenhagen to London flight deals can be genuinely good if you time things right. Budget one-way fares from easyJet start around €33–€40 when booked well in advance, and Ryanair round-trips have been seen as low as €48–€55 in the off-peak window. SAS one-way fares typically start around €45–€60 in economy for flexible-ish dates, while British Airways round-trip fares usually sit in the €130–€160 range at standard booking windows, dropping lower during sales or if you catch a mid-week departure.
To find the cheapest flights from Copenhagen to London, book at least 6–8 weeks out for budget carriers and watch for Tuesday or Wednesday departures, which consistently price lower than Friday or Sunday. Avoid booking during Danish school holiday periods — particularly in October and February — when families travel and prices spike across all airlines. One practical tip: clear your browser cookies or use incognito mode when searching repeatedly, as some booking engines adjust displayed prices based on search history.
Best Time to Book Copenhagen to London Flights
The cheapest months to fly this route are October, November, January, and February. October and November in particular can deliver fares that feel almost too good — London is quieter, the weather is grey but manageable, and airlines are filling seats. January is rock-bottom for prices but genuinely cold in both cities. Spring months (April and May) see prices climb as tourists start moving and city-break demand picks up. July and August are the most expensive period: families travelling during school holidays push fares up significantly on both budget and full-service carriers, and last-minute availability shrinks fast. If you have flexibility, the sweet spot for a reasonable balance of price and weather is late September or early November.
London Airport Guide
Where you land in London matters more than on almost any other European city route. Heathrow (LHR) is the most convenient for central London: the Elizabeth line (Crossrail) now gets you to Paddington in about 15 minutes for roughly £12–£13, or into the City in around 35 minutes. The Heathrow Express is faster (15 minutes to Paddington) but costs around £25 one-way. Gatwick (LGW) is served by the Gatwick Express to Victoria in 30 minutes (around £20) or Thameslink to St Pancras in about 45 minutes for less. Stansted (STN) is the furthest out — the Stansted Express to Liverpool Street takes 47 minutes and costs around £20–£28 depending on when you book. Luton (LTN) requires a shuttle bus to Luton Airport Parkway station before catching a train — total journey to St Pancras is around 50–60 minutes. Factor all of this into your total fare comparison before assuming the cheapest flight is actually the cheapest door-to-door journey.
