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.

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.

KAYAK’s top tips for finding a cheap flight from London to Brussels

  • Reaching London-serving airports for this route is easy, as the city provides excellent public transportation to the airports. Take the Gatwick Express train from Victoria Station direct to London Gatwick Airport (LGW) for a trip that takes about 30 minutes.
  • When deciding which airport to leave from in London, take your ground travel into consideration. Many of the London airports are not based in actual London, making travel times as long as an hour or more in some cases. London City Airport (LCY) and London Heathrow Airport (LHR) are the closest to the city centre at about 15 minutes ground travel time.
  • This flight route has a great deal of airline choice to get tickets from. If your choice is driven by sustainability policies, you can choose from Ryanair or Wizz Air, both of whom are considered Europe’s most sustainable airlines. They both deploy multi-tiered models that have drastically reduced their carbon footprint.
  • If you are planning on taking a small pet to Brussels (BRU), book with SWISS. Dogs or cats under 8 kg are welcome in the cabin as long as they have a full health passport, are micro-chipped and not pregnant. Keep them in a small, waterproof container for the flight.
  • WIZZ Air allows babies under 2 years of age to fly for free, as long as they are seated on your lap for the duration of the flight. Most other airlines will charge 10% of the Economy fare and you will be able to get a bassinet upon pre-book. The airline will always give you an extender safety belt for you and the child.

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

I need assistance and I could not fault it at all. I suffer anxiety and I was always put at ease by assistance staff, and the banter was good. On board the staff was so very nice and kind and showed empathy. Thank you to them. It was my first time travelling since I lost my husband and was so grateful to them.

Great flight just took some time to board even when lining up early for the flight, even taking off took longer then expected.

Nothing unexpected considering it is a Ryanair flight. It does the job. Nothing above, at all.

Take off was great but landing is always with a bump.

Flight was delayed by 1 hour 45 minutes. Aircraft was cramped, dirty and uncomfortable. Boarding staff more interested in charging you for oversize baggage than getting you on board. Overall not a pleasant experience.

A delay of almost 3 hours. It was evident that the staff wanted us to board urgently, to the point of rudeness, to avoid paying compensation

It's not the staff's fault. The cabin crew do their best but the setup in Stansted Airport by Ryanair is poor. The herding of people like cattle is unacceptable before boarding and is something that's in every airport but only in Stansted have I seen the queueing of passengers outside the plane on the tarmac and the crew only turning up with maybe 5 minutes to depart. This is a resource issue . Yes prices are good but seemingly comes with a price of poor treatment of customers. I'll pay more next time

On time arrival but the aircraft had seen better days and needed a deep clean.

It was appalling, full of young people who were drunk and disobeying instructions to sit down. Crew did nothing to enforce. There was a Ryanair pilot sitting in the aisle opposite me who talked through out the safety briefing so loudly I couldn’t hear. Whole thing felt unsafe

Delayed for 2 hours lack of communication no refreshments as promised and the drinks on board were not as ordered and refused to refund

the service on Business class should be improved to be at par with industry leaders like Cathay Pacific and Singapore AIrlines. A lot of room for improvement.

You will pay for everything and feels like the airplane is old

The luggage problem I previously mentioned was actually this flight

The flight was delayed due to snow in Frankfurt. There wasn't much information from BA or the airport, but Kayak was great and kept me informed of the delay and gate changes.

Late takeoff, but on time landing. Lost bags, 3 days to find them, still in transit to my location. Power outlets broken, Wi-Fi not working, so much for working on the long flight.

Good. For a long flight. The comfort of the seat could be better. Also, the food was « normal » plane food. Not indian plane food unfortunately! Everything else was smooth and great.

The seats were comfortable. So many empty seats allowed for stretching out and sleeping. The onboard entertainment was pretty good. The cabin crew were so kind and kept the passengers well- hydrated, and well fed.

We had American Airlines on our return and it was confusing if we were going with Aa or BA I had 2 different flight numbers and didn’t get our gate until it was boarding. So we were a bit nervous as the which it was

No WiFi. No food. 250 ml of water only drink option. No entertainment options. Extremely bare bones flight

Economy seats were good and spacious. Much better than virgin by a mile.
