London (LHR) → Copenhagen (CPH): cheap fares overview
London to Copenhagen is one of those short-haul routes that looks cheap until you actually need to fly it. BA and SK both run direct services — we're talking under 980 km and barely over an hour in the air — so prices should be reasonable, right? Mostly yes, but business demand keeps midweek fares stubbornly high. The route gets squeezed hard in summer (Danish school holidays hit July hard) and again around Christmas markets season. Book early for those windows. Shoulder months like March and October are where the real value hides.
Why travel from London to Copenhagen?
Honestly, Copenhagen converts people. I went for a long weekend thinking I'd tick it off and ended up planning a return trip on the train home from the airport. Travellers from the UK go for the food scene — it's genuinely world-class without being precious about it. Design lovers come for the furniture shops and architecture. Families with Scandinavian connections use it as a hub since CPH connects onward to 200 destinations across the Nordics and beyond. There's also a strong business corridor between London's finance sector and Copenhagen's tech and pharma industries, which is honestly why midweek seats sell fast. And Tivoli — yes, it's touristy, but it's also genuinely magical in a way that's hard to explain until you're standing inside it.
How to find a cheap fare on this route
Flexibility is everything on this route. Flying Tuesday or Wednesday instead of Friday can knock a noticeable chunk off the fare — the London-Copenhagen corridor is business-heavy, so weekend leisure prices are often actually lower. January through March tends to be the cheapest window outside of the Christmas spike. If LHR prices look rough, check London Gatwick or Stansted — different carriers serve those and competition drives prices down. Book six to eight weeks out for the best balance of availability and price. Connecting through Amsterdam or Frankfurt occasionally undercuts direct fares, but honestly — it's barely over an hour direct. Don't waste your afternoon in a transit lounge.

What should I know before booking a cheap flight from London to Copenhagen?
Check baggage allowances carefully, as budget fares may have restrictions; also verify which London airport (Heathrow, Gatwick, Stansted, Luton, or Southend) and Copenhagen airport the flight uses, as this affects your total time and transport costs. Book directly with the airline or established travel sites to avoid hidden fees.
