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.

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

Original flight was canceled, booked another one and find out when checking I was on the waiting list. Horrible experience

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

Flight was late, economy seats are uncomfortable, and there is no entertainment. Food looked good, although I did not eat as it was Ramadan. Flight crew competent and professional. Ticket was not good value for money. Too expensive.

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

I would like to praise one of the stewards, Mohamed, who was swift and efficient to help me as I was not feeling well at some point during the flight.

Food quality was low for business class. No snacks between meals. Very confusing “One World” participation. This airline seems to be part of the program but doesn’t recognize the benefits to customers (luggage allowance)???

Due to the operational delay with Southwest, I missed my connecting flight in New York. Southwest rebooked me with Turkish. Southwest paid for my accommodation in NY, but did not provide food at the hotel. I ended up spending 34 dollars on my dinner. Moreover, in Istanbul, where I transited, I had more than 10 hours of layover without access to the Turkish Lounge. I spent 117 USD to have access to the Yotel cabin for only 4 hours of rest and recuperation from jet lag. This was the most painful trip I have ever had in my life.
