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 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.

FAQs for booking flights from London to Brussels

  • Which is the best airline for unaccompanied minors?

    If your child is flying to Brussels alone, it will be mandatory to book them in with an Unaccompanied Minor service.

They will see your child through the flying process with a crew mate as their personal escort.

If you are in Business Class you will have an expanded menu, which includes far more warm cuisine.

  • Can I take a service animal in the cabin in Brussels?

    Absolutely – all service animals are welcome to be at the side of their owners when they need them most, such as times like flights.

Keep the animal harnessed during the flight and it can be with you throughout. All airlines servicing this flight will welcome service animals.

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

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

There might be more food options for people who can't eat so much starch/sugar/bread/rice. Meat, cheese, walnuts/pecans for snack, maybe jerky or other kinds of meat-based snacks would be better than bread and rice and sweets. I had an extra chardonnay, which was fine. The entertainment was great.

Unfortunately, my flight was cancelled because of some sort of emergency over the Atlantic and had to return to London. While I think British Airways made every effort to mitigate the situation, I must say it was still pretty unpleasant. I do appreciate the fact, however, that British Airways put my safety first…and I think the effort to correct a bad situation was very sincere. But I think the process might be handled better in future.

Horrible leg room - coach seating with empty seat in middle on a 3 across seating. You buy business class for comfort which includes leg room. Absolutely no entertainment options either. Awful experience

Flight was 3h50 and was only provided with a packet of oat cookies and offered a cold drink. Thankfully i'd had breakfast but for a morning flight of that length some sort of breakfast should be included. There were 2 toilets for economy but due to turbulence we couldn't use them until the last 1hr which meant the queue was then huge. Would've been nice to open up the business one for those closest to the front to use.

Crew service was poor and very little difference between premium economy and economy. Disappointed.

My bags never made it on the flight and I now have to wait for them to arrive hopefully tomorrow. You can’t even track your bags in the app to see where they are since they didn’t arrive. You have to file a claim and then wait for them to inform you when you will receive your bag. We were already delayed for an hour due to baggage so I don’t understand how my bag didn’t make the flight.

One of the worst experience given the middle seat even asked for the change no one honored,boarded at the end and overall one of the worst experience

No WiFi in either flight. No leg room, the seat in front of me left dents on my knees and the tray was so low my knees propped it up if I tried to use it.

It was good although our flight to the UK was cancelled and rescheduled for two days later. This was after we were already seated on the plane. We missed the first leg of our trip. BA did put us up at a hotel and paid for our meals but we lost our hotel costs in Glasgow.
