Luggage delayed and delivers 24 hours later … broken. No resolution… no response. We don’t have a suitcase for the rest of our 2 week trip

Luggage delayed and delivers 24 hours later … broken. No resolution… no response. We don’t have a suitcase for the rest of our 2 week trip

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

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.

Suitcase didn’t arrive to Stockholm. Chairs y comfy and not even water is offered

I missed my connecting flight due to long lines at security and immigration. Need improvements

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.

Boarding time was a bit slow causing the flight to not leave right at 5 pm,but other than that it was fine.

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

we had to unexpectedly check a bag, the flight was late getting in

Everything was perfect dood delicious staff were nice excellent and smooth landing great job 👍

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

Cancellation was really bad no organizations at all and I want to choose a direct flight for the 18 January counter agent does not allowed me no even to speak was rude I was forced to got a third world country flight

Good! except for the in-flight announcement which was very poor. The flight attendant was inaudible with her english language throughout the flight. Her communication was bad, very bad. I could not fantom what she was saying in english and she was very fast you could hardly hear or understand what she was communicating. She needs to improve. Thx

Improve food quality and clean the seat . Bathrooms not clean

Intersting crew: only men with a bit of roughness. The food was not bad, but there´s no alcohol option

When the flight landed, it was still going towards the gate, when everybody got up. Nobody cared that the flight was still in "active taxi" mode. But seems like this is common on Air Maroc flights.

This is the worst seat that I ever sat on. The length and width are great but Super uncomfortable. We felt like sitting on marble.

Good but your male staff should be more appreciative of customers. After all you are making a lot of monies from Nigerians.

The plane was new, clean and nice. The crew was very attentive and pleasant. The food wasn’t great, though - even in business class…
