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

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.

On board service was decent. I like the legroom at UA that seems to be more than in other airlines

Crew was enthusiastic. Meal was surprisingly good. They came to give water very frequently. Negative that the seat reclining didn't work

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.

This was absolutely one of the worst experiences of my life. I came to Europe for a 2 week trip and the airline was probably the most disorganized airline I’ve ever seen in my life. They lost my luggage. I had tracking on it for just such an occasion and told them EXACTLY where it was in the terminal and they somehow failed to get it out on the flight that night, since we were leaving for Switzerland the next day there was no way they would get it to our hotel in time. Seriously, take another airline at any cost. It’s not worth whatever you pay…you’ll end up paying a lot more in the end. My medication is in the bag and I can’t get to it and don’t know how I will get it.

my husband's monitor did not work. there was a visibly ill family in my husband's row.

They canceled my flight and they haven’t reimbursed me yet

Easy flight, on time, easy check in but long lines.

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

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

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

The flight itself was fine. The flight was delayed for nearly 10 hours and there was inconsistent communication about why it was delayed.

Good flight overall Welcoming crew Food needs some improvement especially from Casablanca to dc

Had the worst service I have experienced in 45 years of flying internationally (over 100 flights). This was an 8-hour flight and the crew was completely non-responsive to any and all requests for assistance from the 200+ passengers. My wife and I each pressed the button for assistance at least 4 separate times and no crew member ever responded. Looking down the aisle, at any given time at least a dozen passengers request-for-assistance lights were on and no crew member ever assisted any of them either. Notably, it was a very smooth flight with no turbulence, so there was no reason crew members could not provide assistance. Other than two meals - one at the beginning and one at the very end, the crew did not serve water or other drinks at all. We had to get up and walk to the end of the plane to get water ourselves. The only snacks available were saltine crackers. Crew also did not collect trash except immediately after each meal. Plane was a mess and everyone was coughing at the end due to lack of water. We found the crew hanging out in the front of the plane talking to each other and laughing amongst themselves without a care in the world about the 200 passengers. One was just enjoying a book. Don’t ever fly Royal Air Maroc if you can avoid it.

The service was terrible. We weren’t allowed to take water on the flight and the drinks were offered only at the end of the meal. When we used the button to call the flight attendants, they never showed up and when my daughter’s drink was spilled due to turbulences, she asked for something to clean her pants at least 4 times and eventually they gave her a tissue. The flight attendants were rude and overall the flight was terrible!

Old planes that are not being maintained with at least basic cleaning. Plane smells awful, bathrooms not cleaned either. Very uncomfortable chair. Customer service probably one of the worst I have experienced. The AC dis not work, kept us on the plane for over an hour with no water and air condition
