Terrible flight. 1. They’ve only one option for food. 2. Seats are very cramped and screens are tiny 3. No pillow or blanket provided on long haul flight

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

That was a short flight by the only time I could actually sleep

How can a national carrier and part of Lufthansa group not even provide complimentary water and a snack in such a long flight ?

Terrible seats. Whoever designed the seats should try taking a long flight in it themselves.

Food quality is deteriorating each time, last year was very good. I avoid the plane food lately.

Been flying on various airlines, all over the world, for 50+ years. The food on Brussels Air was easily the worst I ever endured.

I have traveled to probably over a hundred locations worldwide, but had only one mixup of airport in Shanghai. Until Iceland and Stockholm. Reykjavik has 2 airports, Stockholm 4 (!). Please indicate clearly when a departure flight is scheduled from an aiport other than the international aiport. That would greatly reduce stress. Thanks

More than one hour detail with no explanation and no compensation

my husband's monitor did not work. there was a visibly ill family in my husband's row.

I ordered a drink, but never got it. I ask what type of drinks they had and they could not tell me and there was not printed copy that I could find that is usually on most airplanes. They served dinner and never walk back to see if any need a drink or anything afterwards until they served the snack just before landing.

Check-in wait time was quite long (understaffed for the volume of customers), but energy and hospitality of flight crew was great!

I really enjoyed the flight…and food and the hospitality but didn’t get the food I requested for.

Everything was terrific. Kevin, and the whole crew, were exceptional. Five stars all around! Thanks so much.

Flight held at gate for other passengers. We ended up being late and missed connection

Should have more cosmopolitan food choices - too many Indian dishes - the only entree not Indian was lamb which I don't eat

I have nothing but amazing things to say about every staff member I encounter on my transport from Brussels (Bru) to New York (jfk) via London (lhr) after many flight delays and changes every colleague I asked for help gave me the utmost respect and did everything in their power to make sure I arrived in Washington DC to make it in time for my brothers wedding. The flight attendants on the flight from Bru to lhr move me to the front of the plane so I could get off quickly and try to make it to my connection to dc, when I missed that wagans at the support desk did everything in his power to get me to dc via two transfers. Especially during the busy holiday season I am so so grateful for the amazing customer service that I encountered today.

Firing with British airways leaves me feeling stressed and disappointed. They are substandard in so many aspects of airline travel.

Worst trans-Atlantic flight in years! The seats were incredibly tight, both in width and depth. The back selection was so cold, it was like traveling in a refrigerator. Although I had an entire row, the seat arms would not go up, so I could not take advantage of it to sleep. However, the crew was smiling and helpful and really seemed to enjoy their jobs. The food was the worst I have ever experienced on any flight. The PA system blasts announcements to the point of hurting my ears when using the audiovisual equipment. Not safe or sat. Also, I did not like the bait and switch tactic. I put in a search with one bag and the other flights had put that into their price, but BA did not and made me pay extra for it which would have made the price comparable to others. Also, even at check in there was no “choice” of seat, unless you paid extra for it even in the same row. No other airline I have been on does this. Once check in begins, normally, you can choose any unoccupied seat in your category. These tactics and the lack of comfort means I will never fly BA again.

An early flight and a bit confusing where to check in with British Airways; good we asked at the information counter the night before as we stayed overnight at the Sheraton on the departure level.
