WE didint profit of food , but for the other think all was good

Spacious and clean aircraft. Good food. Economy will always be squeezed but thankfully I had an aisle seat for stretching exercises. Good selection of movies, particularly Spike Lee joint.

Unfriendly, 8 hours delayed, no lounge access even flying business. Don’t fly Brussels

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

Baggage check is an aggravation. We had four 4 bags, if a bag is just .10 of a kilo you cannot check it on AC self baggage check. It is not possible to check the weight of the bag at the self checking. Should you check a bag that is under the limit it will go right through and you can’t get it back to redistribute weight from a heavier bag.

I cannot think how they could put more seats together but they did. So elbow to elbow leg to leg for these long journeys they should consider leg space at least. Since they did not offer to check people's carry one space was tight and if you did not get on first people used your assigned overhead storage so now your doing these same to another. Cascading inconvenience.

Despite exit row seating, which gave leg room, seating was so narrow, the next passenger spilled over onto my seat. WiFi did not work.

It was okay. The seating didn’t give you much space especially when you book a premium. It was still pretty close. The seats had no screens which was a disappointment. The crew was awesome though. Again I wish the wait between families with children boarding and general boarding was a little longer to give families some time to get situated especially those bringing a stroller like myself or for solo parents travelling like myself who has to do everything. The time between boarding zones especially with chilling is so short, I had to gate check my stroller and did not have enough time to pull it down and transport my luggage inside all while having my infant strapped to me or to even ask a flight attendant to assist as they’re busy with the the general boarding going on

Flight itself was not bad at all. However: my checked bag (checked in Calgary) did not make it onto this flight as I found out after I landed at EWR. I still don't have it but it appears that it is on its way to me.

The crew was amazing! I was a bit surprised and disappointed that there was not wifi available for personal use. The only thing I would change would be the seat cushions. They are not comfortable at all for long flights.

Flight and attendance were very good we had 2 hour delay that took the shine of it

Rude flight attendants with poor service. Worst first class experience I’ve ever had.

The plane was very cramped to point there was no way not to touch person beside you and a stewardess screamed at my son when I touched her arm to get her attention to let her know she forgot to give him his dinner when she passed him and gave a dinner to passenger behind him. Very inappropriate response and She never came back to apologize and other stewardess said she was sorry “if I felt” she was inappropriate. Horrible experience and she should be reprimanded for her behavior

The seat design in the premium economy section leaves virtually no room under the seat to store a bag or purse. Other than that, it was a great flight. Arrived early.
