Pros: Pleasant staff. Comfortable plane. Second leg from Brussels to Frankfurt was great.

Cons: Check in at Manchester was a joke. No signage for Brussels Airlines to start with and no one to help. Long queue, over 1½ hours to drop a bag after checking in on line. Every other airline was way faster. Thankfully, security was relatively quick.

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!

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,
