Everything was better but france airlines more better than them

Good leg room for people of all sizes. Pleasent crew.

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

They canceled my flight and they haven’t reimbursed me yet

They canceled my flight and they haven’t reimbursed me yet.

On time, kind staff but the aircraft was not clean

Easy flight, on time, easy check in but long lines.

Dirty seats, entertainment unit not working. The crew member assisting in giving boarding passes was rude. She didn’t give us the seats we bought and then tried to give us 4 seats saying they were in the same row which they were not. We had paid for our seats to be assigned!. Food was bad, service was poor. My son had asked the hostess for a sprite which she told she would get but did not

The Airline canceled my flight and don’t want to refund me.

My luggage was left behind in Miami. I wasn’t the only one. I couldn’t get a boarding pass from air Maroc but I got one from American Airlines for the air Maroc leg. I had the sense of getting in line with air Maroc boarding crew and showed them my AA boarding pass for air Maroc and I got a new one from them. There were several passengers filing missing bags reports in Casablanca so I assume there isn’t a good coordination between airlines. My AA bag ticket says Casablanca but it is from AA. I wasn’t the only one missing a bag.

I couldn’t find my boarding pass with the information provided by Underpricer. It took me several hours to find what the issue was. Finally I got the right code to get my boarding pass from American Airlines. Underpricer WhatsApp call center finally got it right. When I got to Casablanca my luggage was left in Miami. Not sure which airline fault it was if Air Maroc or AA. I filled out a report with Air Maroc

Had problems with online site and app when trying to book flight and manage reservations. My in-flight console did not work and seat did not recline. Staff could not provide details with respect to short connection. Fortunately a fellow passenger was helpful. Otherwise good flights, on-time departures/arrivals, etc.

Horrible. Flight was overbooked and I was put on a flight to Miami without a leg to my final destination. And Kayak is not helping resolve the problem
