Brussels (BRU) → Copenhagen (CPH): cheap fares overview
Brussels to Copenhagen is a short hop — 755 km, under an hour in the air — but the fares don't always act like it. SN and SK both run direct service, which keeps prices competitive most of the year, though business travelers fill those seats Monday mornings and Thursday evenings and the airlines know it. Expect rates to climb during Danish summer (June through August) and again around Belgian school breaks in February and November. The sweet spot tends to be early spring and mid-autumn, when neither country is pulling crowds and both carriers want to fill planes.
Why travel from Brussels to Copenhagen?
Belgians make this trip for more reasons than you'd think. Copenhagen has become a serious food destination — not just Noma's legacy, but a whole scene of natural wine bars and smørrebrød spots that genuinely rival what Brussels does with its own cuisine. Design lovers come for the furniture shops and architecture. Families with Danish relatives make the run regularly, especially around Christmas. There's also a growing business corridor between the two capitals — pharma, shipping, EU-adjacent consulting. And honestly, Scandinavian work-life culture has a pull for people who want to see how the other half lives. Copenhagen rewards slow exploration, and it's close enough that a long weekend actually makes sense.
How to find a cheap fare on this route
Book four to eight weeks out for the best prices on direct flights — last-minute on this route gets expensive fast. January, February, and October are historically the quietest months for fares. If you're flexible, check Tuesday and Wednesday departures; weekend flights on a route this popular carry a premium. Copenhagen's main airport is well-connected, but Amsterdam or Hamburg can occasionally undercut BRU fares if you're willing to add a train leg on either end. I'd skip connecting routings here — with a 53-minute direct flight available, a two-stop itinerary through Frankfurt rarely saves enough to justify the extra hours.
Frequently asked questions
What is the cheapest month to fly from Brussels to Copenhagen?
Shoulder seasons like April-May and September-October typically offer the best prices, while peak summer (June-August) and winter holidays are most expensive. For the lowest fares, avoid major holidays and school vacation periods.
How far in advance should I book a flight from Brussels to Copenhagen?
Booking 4-8 weeks in advance generally offers the best prices for this route, though deals can appear at any time. Last-minute bookings within 1-2 weeks are usually more expensive unless flash sales occur.
Should I book a direct flight or consider connections to save money?
Direct flights (operated by SK or SN) take just 53 minutes, making connections impractical and rarely cheaper; the time saved and convenience of direct service typically outweigh minimal savings from connecting flights. For this short 755 km route, direct is almost always the better choice.
What currency and payment information do I need to know when booking?
Belgium uses the Euro (EUR) while Denmark uses the Danish Krone (DKK), so expect currency conversion fees if paying in DKK; most booking sites allow payment in EUR or your home currency. Check your bank's exchange rates before booking to avoid unfavorable rates.
What should I know before booking a cheap flight on this route?
Check baggage allowances carefully, as budget-friendly fares often include only carry-on luggage; also verify that your chosen airline (SK or SN) includes seat selection and other basic services in the base price. Booking directly with the airline sometimes offers better transparency than third-party sites for this short European route.
