Pros: My flight was over four hours delayed and I appreciated that when I got to the airport and found that out, I didn’t have to ask for anything but was immediately greeted with a food voucher. I lost an entire days worth of vacation in Germany, so well I do feel the British Airways should have done better and should’ve compensated me better, the fact that they immediately took steps to make the situation better was greatly appreciated. That level of customer service was beyond any I’ve received with an American-based airline. Also, the crew on the plane was fantastic and a great choice of movies. I flew American on the way home and was shocked at the lack of customer service and rudeness, I will happily fly British Airways again and again.

Pros: Nothing

Cons: I am handicap, I travel with a scooter. We let them know months in advance and still they did not plan or assist. My scooter was not brought up in Brussels or DC, I refused to leave the plane in DC until they finally brought it to plane. They sat me in row 38...I can only walk a few feet so the airline failed in every aspect...epuc fail. I will never fly Brussels airlines again.

Cons: There was someone that pooped themselves, another that threw up, and the flight attendants were so rude. They kept spraying stuff in the air and even those of us sitting, so much in fact I had an asthma attack and had to use my inhaler. When I told the attendant, she said "theres nothing I can do," and kept spraying the air with this awful spray. The flight harmful to my health, exhausting, and uncomfortable. BEWARE OF THIS AIRLINE! I would have preferred not gone on my trip then fly this airline!

Prices are per person and are for e–tickets and include all taxes & fees in USD.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller.
At KAYAK we don’t set the prices, so it’s not possible for us to guarantee what other companies are selling.

We compile tonnes of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we can't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.

If you have more questions or if you have a bad price to report to us,
