Everything was better but france airlines more better than them

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

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

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

Actually this is my first time using airline I was in every single thing that happened throughout our journey, the appearance of the plane inside furnished about the seating the flight attendants and many many more I was so excited throughout thank you Brussels Airlines for the great service.

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

The crew and the flight were excellent, the food might be better!

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

I like the frequent mails we get when there is an update. Please keep it up

in the front - higher class of business - sitting in the same seat (with one empty in the middle) is not acceptable any more. need the business class to be as we paid for.

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

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

Extremely Disappointing Experience Boarding was chaotic and poorly managed—we were left standing in the heat for 30–45 minutes with no explanation or apology. As a business class passenger, I was shocked when a staff member rudely refused to let me board after I questioned why I had to check in my carry-on, which contained valuables. Despite explaining my concerns, he remained unreasonably inflexible. Thankfully, the captain intervened and retrieved my bag personally. This same staff member was also loud and disrespectful to several other passengers. Completely unacceptable service.

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.

It will be my last choice to fly this airline It was the first time to fly with them Everything extremely bad Nothing good about them Very filthy Bad service Bad food quality Bad boarding Very bad lounge. Actually it doesn’t meet the definition of lounge

Check-in could have been a little early and I wished the airline would have serve some better real food rather than serving a very hard bread for a 8hrs flight.

Comfort and organisational prowess of the entire crew. Baggage handling can be better. No had all my luggages after 6days of the flight.

3 hours late, came at my final destination without any of my luggage.

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

Old planes that are not being maintained with at least basic cleaning. Plane smells awful, bathrooms not cleaned either. Customer service probably one of the worst I have experienced.
