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.

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

Actually this is my first time using airline I was in every single thing that happened throughout our journey, the appearance of the plane inside furnished about the seating the flight attendants and many many more I was so excited throughout thank you Brussels Airlines for the great service.

On board service was decent. I like the legroom at UA that seems to be more than in other airlines

It was really good because the employees were very nice and fun to talk to. The entertainment was nice because they had plenty of movies to watch.

Crew was enthusiastic. Meal was surprisingly good. They came to give water very frequently. Negative that the seat reclining didn't work

That was a short flight by the only time I could actually sleep

How can a national carrier and part of Lufthansa group not even provide complimentary water and a snack in such a long flight ?

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.

Boarding was fairly chaotic. One of your employees clipped my ankle as he was passing with an empty wheelchair and not only did not apologize but stated something to the effect of “oh forGod’s sake.” There was plenty of room for him to pass. otherwise, everything was excellent.

As I said Al & AJ were absolutely the best and wow they should be recognized for their amazing service!

Better training for staff, I didn’t even get a napkin with my drink so it was dripping all over !

Fantastic! Great seats! Friendly staff! Amazing selection of shows and movies! Smooth ride! I don’t know what more I could have asked for honestly. They made flying a breeze this time around.

Had a very bad experience flying out of London. Our initial flight was cancelled without notice and the next flight had a layover of 8 extra hours. Me, my husband and my 8-year-old were already sick, and this further added to our problems. We paid extra for the seats: I was not even given our chosen seats which we paid for months before the trip. We were shoved into the available seats which were middle ones in the back (we had paid for front window, aisle, aisle). The seats were so uncomfortable and getting out of middle seats every so often (with a sick child) was a task. We had initially chosen British Airways because of the short layover, however, that went out of the window. Although unexpected things happen all the time and I understand customers have to adjust for the unplanned, however, how the airlines react and make the passengers comfortable during that time is the real test. We were not given any compensation for food or any arrangement to stay comfortable during that time. In fact, our paid seats were taken away as well.

The food could have been better. And the chicken sandwich was not nice at all.

Not the quality I was expecting from a company that has been around for ages and charges high prices

The whole experience was very disappointing. Drinks could have been served and offered more frequently. The seats were reasonable but considering I paid for premium economy, I felt cheated. I flew premium economy with Japanese Airlines ANA 5 years ago and their service was by far, superior. We had access to the club lounge, better seats and excellent service. Out of 10, I would rate the experience as 4. Everything felt cheap and the Airbus aircraft are far better and more comfortable

Hand bag was taken to be checked in at boarding gate

Flight was okay however bags were left in London even though we had a 7 hour layover. Bags are yet to be confirmed to reach final destination. Horrible work.
