Flying from London Heathrow
Heathrow is the UK's main long-haul hub and the airport where full-service carriers concentrate their schedule rather than chase price. Expect five terminals, fast Tube and Elizabeth Line links into central London, and a route map that skews toward business-traveller frequency: more daily slots, fewer fare wars. Short-haul fares from Heathrow tend to run a little higher than Gatwick or Stansted on the same corridor — the trade-off is a wider choice of airline and a more reliable timetable.
Arriving in Brussels
Brussels Airport is 12 km northeast of the city, with the Airport Express train reaching Brussels Central in 17 minutes for €9.30. Brussels Airlines, BA and easyJet share the route. Eurostar via Lille is often the better central-London option for total journey time; fly when you need to connect onward through Brussels' network rather than for the city itself.
