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

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

All great. Very efficient. Good emails that kept us in the know

The boarding process would have been better. When people are flying internationally and the airline is a member of Star Alliance they cannot have different rules for carryon baggage. Brussels Airlines made us adjust the weight of our carryons based on their rules even though we were flying international and our next flight was with United which does not have weight restrictions for carryons. That was just ridiculous.

Terrible seats. Whoever designed the seats should try taking a long flight in it themselves.

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

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

More than one hour detail with no explanation and no compensation

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

They robbed me, filed a complaint and they ignored me

The crew was friendly, 5/5 stars. The food was better than ok, 3.5/5 stars. The seats were tight, 3/5 stars. The entertainment was 2/5 stars because of lack of WiFi.

There is nothing Royal about Royal Air Maroc. Old planes, poor service, no entertainment and not one of my 4 flights was on time.

the whole flight is bad from Miami to Casablanca and from casablanca to Miami. Delays, service, food, .... Not flying again with this airline

3 hour delay, very rude flight attendant the food was horrible.

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.

There was a technical problem with the aircraft after we boarded and we had to leave the plane and wait for two hours where we couldn’t talk to anyone. I had a connection in Toronto to Vancouver I obviously missed it. Arriving to Vancouver the flight was canceled and I wasn’t offered any another flights. I had to book one on my own charges to get back home. Also at Casablanca check in. They said our luggage will go to final destination and they did not!

Long delayed that cause missing my connection. Accommodation and food at the Casablanca airport was horrible

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.
