We missed our connection and they put us in a hotel our luggage didn't get rerouted with us so we arrived with no luggage

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.

ldid not like the late departure did not like the late food service. Food should have been serve earlier ro allow more sleeping time. Did not like beeing interrupted just to show announcement about their duty free onboard Finally baggage did not make it to final destination and are still in casablanca.

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

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.

Improve food quality and clean the seat . Bathrooms not clean

Stay away at all cost! Late boarding, late departure, inoperable seat controls and entertainment screens, very rude cabin crew,

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

Plane is dirty Food quality poor Service was not good Lounge extremely bad
