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

Insights shared by verified travellers who flew the route from Heathrow 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.
