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 AirwaysLHR-BRUFeb 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 AirwaysLHR-BRUJan 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.

I wish that the meal included a vegetable or even a salad instead of couscous! Why serve chicken with rice AND couscous? Service was good overall though a bit lacking in friendliness. Usually on air france I've been offered a glass of champagne before dinner, wine with dinner, and a digestif after dinner. We were only offered wine this time!

Usually on air france I've been offered a glass of champagne before dinner, wine with dinner, and a digestif after dinner. We were only offered wine this time!

It was not Air France but Air Europa. But confusion over our checked luggage. Whether it was checked all the way to Tenerife or not. It was not. Had to line up again in Departures. At least our Sky Priority was honoured. Flight was fine.

My wife and I had a row to ourselves after moving seats. There were no TVs and you had to buy food. So we did nothing but had a quick nap. Flight was fine.

Georgian Airways check in staff initially denied us, because they thought passengers required transit visas to transfer on connecting flights. This required 70 minutes for them to call multiple people to confirm how transfers worked. They did not apologize once accepting our check in. Onboard, the four hour flight gave stale bread with spam slices as lunch. The only included drinks were still or sparkling water.

I did not get my baggage at my final destination..poor coordination with connecting flights with partner airlines (Saudi airways). Also the food was very mediocre.

Not a good one this time. The absence of internet without any information/notification ahead was really the unacceptable part. Also this new A350-900 has a serious legroom challenge for economy seats. It’s more like a medium-haul flight legroom configuration.

Not great , just ok . I expected better food but it did not deliver . Flight staff was ok . The guy at the drop off bag counter was the only saving grace in this whole trip . He was pleasant, friendly and very helpful . You couldn’t ask for a better assistance from him .

There was 2 hours delay before boarding and 2 hours delay after boarding while waiting in the plane

Very good crew. Food service above average. Seats very small for a 12 hours flight.

Boarding was a disaster being moved by Air France by bus to the plane. The plane should have been at the right gate.

The flight went well, only during the flight from Brussels to Vilnius I would have liked if they had at least given us plain water to drink.

The boarding process would have been better. When people are flying internationally and the airline is a member of Star Alliance they cannot have different rules for carryon baggage. Brussels Airlines made us adjust the weight of our carryons based on their rules even though we were flying international and our next flight was with United which does not have weight restrictions for carryons. That was just ridiculous.

We waited in line for more than 30 minutes to go through the check in (after the staff summoned us). Once on the plane we had to wait almost two hours before takeoff. The copilot said that it was not their fault but that the plane had arrived late in the first place and lost the slot to leave again because of the heavy traffic, This is completely understandable in our times, but I would have expected a little bit of pampering from the staff. We received a tiny little cup of water because we complained. Not a coffee, not a cookie, no music on the plane, no plugs to recharge your cellphone. It was very cold inside the plane and someone asked for a blanket for a baby - very harsh answer from the staff, no blankets on this plane. I think they should review their instructions and team spirit as traveling is also the experience, not only getting from A to B. And it’s not fun to interact with staff that doesn’t seem like they are enjoying their job. And as far as I know and judging from the cost of the ticket Brussels Airlines it’s not even a low cost!

Terrible seats. Whoever designed the seats should try taking a long flight in it themselves.

The crew and the flight were excellent, the food might be better!

This was absolutely one of the worst experiences of my life. I came to Europe for a 2 week trip and the airline was probably the most disorganized airline I’ve ever seen in my life. They lost my luggage. I had tracking on it for just such an occasion and told them EXACTLY where it was in the terminal and they somehow failed to get it out on the flight that night, since we were leaving for Switzerland the next day there was no way they would get it to our hotel in time. Seriously, take another airline at any cost. It’s not worth whatever you pay…you’ll end up paying a lot more in the end. My medication is in the bag and I can’t get to it and don’t know how I will get it.

I missed my connecting flight due to long lines at security and immigration. Need improvements

Food quality is deteriorating each time, last year was very good. I avoid the plane food lately.

Been flying on various airlines, all over the world, for 50+ years. The food on Brussels Air was easily the worst I ever endured.

I felt the overall quality of the plane and food service was less than that of their partner airlines, United. An example was wine was served in paper cups in premium economy class. There was no real silverware, napkins or a welcome kit other than a pillow and blanket.

The seats on the plane and at Heathrow Airport are so uncomfortable

They did not provide free WiFi, It could be purchased for, I think, around $25, This seemed excessive.

Good flight, awful, vindictive, vile customer services in T5 Heathrow.

Ok we did get an upgrade and the flight was delayed 45 minutes BUT without any bias. The crew were excellent, friendly, efficient and verging on exuberant, they all were so happy to do their jobs. Food excellent and the new safety video is fun to watch.

Reliable, great value, but not outstanding in any aspect. This is similar to the experience you get in most international carriers like Etihad or Delta.

Aer Lingus was the actual airline so they handled everything professionally.

Flight got diverted because of an emergency and the crew were fantastic and probably saved that passenger’s life. While in emergency landing some measures could have been taken to prevent additional delays. In general not great experience with BA. I used to fly BA years ago all the time, very disappointed by the whole experience, seats were tight, bathrooms tight.

Business class area too small and chair and equipment not comfortable .

Lost my luggage in London Was double charged for luggage

BAD!!! due to delay I missed my connection in MEX, had to pay for hotel and new flight for next morning increasing my spent for $1,000 usd
