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

Insights shared by verified travelers who flew the route from Heathrow to Brussels 
Verified travelerFlew with British AirwaysFeb 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 AirwaysJan 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.

Everything was better but france airlines more better than them

Good leg room for people of all sizes. Pleasent crew.

WE didint profit of food , but for the other think all was good

Spacious and clean aircraft. Good food. Economy will always be squeezed but thankfully I had an aisle seat for stretching exercises. Good selection of movies, particularly Spike Lee joint.

Unfriendly, 8 hours delayed, no lounge access even flying business. Don’t fly Brussels

Flight from London was delayed so missed the connecting flight. Taking 2 days to get to destination which should have only taken a few hours.

Suitcase didn’t arrive to Stockholm. Chairs y comfy and not even water is offered

I never board the flight. My visa was delayed and when I tried calling Kayak, no one answer and I still have not heard from anyone.

All great. Very efficient. Good emails that kept us in the know

Original flight was canceled, booked another one and find out when checking I was on the waiting list. Horrible experience

Food is horrible. Flight was good and the staff were mostly men.

Delayed suitcase - terrible service to get my suitcase next day, I was informed it would arrive today in the afternoon (Jun/28). Now, I was informed I may or may not receive it until 3 am (Jun/29).

Seats were comfortable, but boarding was the worst I've ever seen. Way too much walking to get onboard as we had to go up & down steps several & then bus took us halfway around the airport for boarding & had to board outside after a very long bus rood.

I will never want to book with these people. They are arrogant and rude. Food was really really bad, crew was even worst

The plane was so old, it needs to be retired! The windows were rattling we paid for premier economy and there was no footrest. Video console was so old, barely had any games for kids. Video console is very slow to react. The gaming console was broken. The foldable food table was sticky and the air hostess had a rough time opening it and closing it for us!!

Generally very good. I think their service is better than some other big names I used to travel with. Their food variety is second to none - and you can place order beforehand. Their seating design is a bit awkward for service, I'd say. Flight attendants must be tall enough - long legs and arms - to reach the window seat passenger while crossing over the isle passenger. Also appreciated the variety on entertainment.

Could have used more leg room for “business class” which is basically coach with a middle seat blocked. Crew was friendly, attentive. Zero entertainment.

Paid for first class and was surprised that the seats were the same in economy except no one was in the middle seat. I expected an actual first class seat.

Captain handled the precaution of return to stand very well.

This flight had seats that were more comfortable than the trans-Atlantic flight I had come on. Boarding, however, was atrocious. There was no point in boarding groups since everyone ended up on the same bus to get on the plane. And the bus ride took forever to get to the plane. The snacks can barely even qualify as snacks. Make sure you bring your own or eat before getting on,
