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 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.

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.

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.

Too cramped up for the better seats I paid for.

I didn’t like my seat in my return flight from Montreal to Orlando at all; considering I paid extra for better seats. That middle seat was cramped up way too much.

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

Bad baggage and people management at boarding forcing me to dispatch my bad despite being the perfect size and respecting everything perfectly, whereas many did not and many free empty spots on the plane as usual… making me loose time and my planned bus at arrival to go to Geneva. Costing me 100 euros extra! So Brussels airlines needs to refund me

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

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 good. Couldn’t Check in online and select seats

It was great. Enough space and room for legs . Great service to.

⭐ British Airways Review — A Journey of Highs, Lows, and Lessons ⭐ I recently flew Business Class round-trip from Boston to Mumbai with British Airways, and my experience was a tale of two extremes — from disappointment to exceptional service, and then back to inconsistency. Boston → London: A Surprisingly Poor Start My journey began on a disappointing note. On a 6-hour Business Class flight, I was surprised to discover that there wasn’t a single proper vegetarian meal option available. I was offered a few bakery items only after repeatedly requesting something to eat. The flight attendant shrugged, offered no solution, and eventually — quite literally — threw some bread at me after much delay. This was not only disheartening, it was extremely surprising given my wonderful Business Class experience with BA last year. I stepped off that flight genuinely hungry and had to make a mad dash to the lounge just to get a proper meal. London → Mumbai: A Complete Turnaround The next sector restored my faith in British Airways. The entire crew was warm, welcoming, attentive, and genuinely caring. A special shoutout to Phiroze and the entire team serving the Business Class cabin — their professionalism, hospitality, and thoughtful service were extraordinary. They truly embodied what makes British Airways a global leader, and I am deeply grateful for the experience they provided. This is the BA I know and love. Mumbai → London: A Strange Meal Schedule This sector was generally fine, but the meal timing was puzzling. Lunch at 10:30 AM — for a Business cabin — felt unusual, and most passengers, including myself, barely touched it. The rest of the service was smooth, but the scheduling definitely needs a rethink. London → Boston: Mixed Experience Again The flight itself was decent, but the Business Lounge at Heathrow for this leg was a letdown. Arrived during lunch hours: no hot vegetarian options available Lounge area: dirty dishes everywhere Even after politely alerting the staff, the dishes were ignored and left uncleared For a premium cabin passenger — and at one of the world’s busiest international hubs — this was disappointing. Overall Impression My journey with British Airways felt inconsistent — two great sectors sandwiched between two that fell short of the BA standard. When BA is good, it is world-class. When it misses, the gap is noticeable. I genuinely hope the airline takes this feedback as constructive insight. I continue to believe in British Airways, and I commend the outstanding crew on the London → Mumbai sector — they were the highlight of my entire trip. With a little more focus on vegetarian meal availability, lounge service, and consistency across crews, BA can ensure every Business Class passenger experiences the premium journey they promise.

We were in business class and I had seat # 1. This was a night flight and after dinner was served, lights were dimmed and I went to sleep. The crew were loud and noisy so I didn’t get much sleep. I expect the crew to enjoy themselves but would Appreciate some decency in staying quiet while the passengers sleep

Have travelled business class with other airlines who profess to be the best in the world. They can however not beat the service and comfort that BA provide.

Great on board entertainment Tasty food Cattle class obviously crammed but not as bad as shorter hall flights

Logan gate staff was unhelpful. Arrived early, come to find out the airbus scheduled was reassigned and I did not have a seat. The desk agent spoke to his supervisor who instructed him to give me a boarding pass to get up to gate area, he was polite. At the gate the fellow was sitting to the side with two other BA staff . I asked him if he could help me, his answer was” we are on a break, we are closed” then turned his back. I am almost 70, drove 4 1/2 hours to Boston and had been looking forward to this trip for 5 months. I have worked in service many times in my life and this is not how it is done. I eventually (1/2 hr) before boarding was able to get a seat. The rest of the flight experience was unremarkable.

The boarding process was chaotic at LHR and the seat was not as comfortable as other airlines....

Great flight. One unique individual assisting in business class who should have not been there. Need more generic meals, not British centric.

We always use BA due to the direct flight options, we have always had a pleasant flight with BA.
