Cheap flights from London to Brussels

October is the cheapest month for this route, and the fares page tracks prices month by month from September through to August, so you can see how the year moves. Late autumn and the quieter weeks of winter are usually calmer than the summer school holidays and the Christmas run-up, when both capitals fill with visitors. Midweek departures and returns tend to cost less than Friday evenings and Sunday nights. Book a few weeks ahead for spring and summer travel, and keep an eye on the price calendar for the weeks around Belgian and British public holidays, which push fares up on both sides.

Easyjet and Norwegian keep the low-cost end of this route busy, with fares that strip out most of what you would otherwise take for granted, so read the fare conditions before you compare. British Airways and Brussels Airlines are the full-service names you will see most often on nonstop departures from Heathrow, Gatwick, Luton, Stansted and London City. KLM Cityhopper, KLM Royal Dutch Airlines, Lufthansa, Lufthansa City Airlines, Helvetic Airways and Malta Airlines appear mainly on connecting itineraries, which take longer and add a change of plane. What is included differs by fare type on every one of them, so compare the total, not the headline fare.

Brussels Airport is the only airport serving the Belgian capital, so every flight on this route lands at the same place, a short ride outside the city. The airport train is the quickest way into the centre, with taxis and buses as the alternatives if you land late or carry a lot of luggage. Allow time at the other end too: if you fly into Heathrow, Gatwick, Luton, Stansted or London City on the way home, check which one, because they sit in different directions and the transfer into central London is not the same from each.
