Frankfurt (FRA) → Copenhagen (CPH): cheap fares overview
Frankfurt to Copenhagen is one of those short-haul routes that looks simple on paper — under 700 km, barely 48 minutes in the air on LH or SK — but the pricing tells a more complicated story. Business demand keeps midweek fares stubborn, especially Monday mornings and Thursday evenings when Scandinavian corporate travelers are moving through FRA. Prices soften noticeably in the shoulders of spring and autumn. Summer spikes hard, partly because Copenhagen draws serious tourism volume, partly because Danish school holidays and German Ferien rarely align, meaning demand stays elevated for an extended window rather than peaking cleanly and dropping.
Why travel from Frankfurt to Copenhagen?
Germans go to Copenhagen for reasons that are genuinely hard to explain to people who haven't been. There's something about the city's pace — the cycling culture, the architecture that doesn't try too hard, the food scene that's world-class without performing about it. Frankfurt residents specifically make this trip for design and furniture pilgrimages, for the kind of Nordic minimalism that's everywhere in shops and galleries. Families with Danish relatives or partners make this one of the most consistent repeat routes in the region. Then there's the business angle — Copenhagen is a serious tech and pharma hub, and FRA's 291 non-stop connections make it a natural European base to connect through. CPH itself opens up 200 onward destinations, so plenty of travelers are using this as a stepping stone into Scandinavia.
How to find a cheap fare on this route
Book four to six weeks out for the best balance of availability and price — this route moves fast once summer locks in. January through early March is genuinely cheap and underrated; Copenhagen in winter is cold but functional, and the city empties of tourists. If you're flexible, mid-afternoon departures tend to undercut the morning business rush on LH and SK both. There's no obvious nearby alternative airport worth the hassle on either end — FRA and CPH are both well-positioned — so don't waste energy chasing Billund or Malmo unless you're already heading that direction. Check prices across a full week on any given trip, not just your ideal dates.
Frequently asked questions
What is the cheapest month to fly from Frankfurt to Copenhagen?
Typically, shoulder seasons like April-May and September-October offer lower fares than peak summer travel. Winter months (November-February, excluding holidays) can also provide budget-friendly options, though weather may affect schedules.
How far in advance should I book to get the cheapest flights?
For European short-haul flights like Frankfurt to Copenhagen, booking 2-4 weeks in advance generally offers competitive prices. Avoid booking last-minute or during peak holiday periods when fares tend to spike.
Should I book a direct flight or consider connecting flights to save money?
Direct flights (approximately 48 minutes) are operated by Lufthansa and SAS, making them convenient for this short 678 km route. Connecting flights rarely save money on such a short distance and add major travel time, so direct is typically the better value.
What currency and payment information should I know when booking from Germany to Denmark?
Germany uses the Euro (EUR) while Denmark uses the Danish Krone (DKK); most booking websites allow payment in either currency. Both countries are EU/SEPA members, so credit card and bank transfers are secure and widely accepted.
What should I know before booking cheap flights on this route?
Check baggage allowances carefully, as budget fares may have strict carry-on limits; both Lufthansa and SAS offer options to add luggage. Verify your passport validity (EU citizens can travel with ID cards) and consider booking directly with airlines or reputable travel sites to avoid hidden fees.
