Flights from London to Brussels: the best tips from KAYAK users' own experiences

Insights shared by verified travellers who flew the route from London to Brussels 
Verified travelerFlew with British Airways-Feb 2024
Have patience. Heathrow is crowded and they don’t post the gate until the last minute. Be prepared to travel a long distance to the gate once it gets posted and go immediately.
Verified travelerFlew with British Airways-Jan 2024
Be prepared. BA didn't provide a gate until 45 minutes pre-boarding, with only a 15-20 minute window for passengers to "board" a bus, to take them to their plane.

KAYAK’s top tips for finding a cheap flight from London to Brussels

  • Reaching London-serving airports for this route is easy, as the city provides excellent public transportation to the airports. Take the Gatwick Express train from Victoria Station direct to London Gatwick Airport (LGW) for a trip that takes about 30 minutes.
  • When deciding which airport to leave from in London, take your ground travel into consideration. Many of the London airports are not based in actual London, making travel times as long as an hour or more in some cases. London City Airport (LCY) and London Heathrow Airport (LHR) are the closest to the city centre at about 15 minutes ground travel time.
  • This flight route has a great deal of airline choice to get tickets from. If your choice is driven by sustainability policies, you can choose from Ryanair or Wizz Air, both of whom are considered Europe’s most sustainable airlines. They both deploy multi-tiered models that have drastically reduced their carbon footprint.
  • If you are planning on taking a small pet to Brussels (BRU), book with SWISS. Dogs or cats under 8 kg are welcome in the cabin as long as they have a full health passport, are micro-chipped and not pregnant. Keep them in a small, waterproof container for the flight.
  • WIZZ Air allows babies under 2 years of age to fly for free, as long as they are seated on your lap for the duration of the flight. Most other airlines will charge 10% of the Economy fare and you will be able to get a bassinet upon pre-book. The airline will always give you an extender safety belt for you and the child.
