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.

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.

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

Bad baggage and people management at boarding forcing me to dispatch my bad despite being the perfect size and respecting everything perfectly, whereas many did not and many free empty spots on the plane as usual… making me loose time and my planned bus at arrival to go to Geneva. Costing me 100 euros extra! So Brussels airlines needs to refund me

I never board the flight. My visa was delayed and when I tried calling Kayak, no one answer and I still have not heard from anyone.

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

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.

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

It is nice and great but the houstees crew are all the way back arguing with customers and behavior issues same of the crew i saw that also all the trips were very much butter!

I have my baggage left either in Jeddah or Addis and undelivered to Abuja

The crew was not helping us in the airports ..Very bad experience..the washrooms are not meeting the expectations..need more good service... The hotel service was good but there is a very long wait time which wasted time to go through..

Need to do a lot of improvement on service and cleaness

The Boeing 737 MAX on this route, flown in the middle of the night, is an UTTER FAILURE for business travellers. The whole point of business travel is to arrive alert and recover from travel quickly, and this little aeroplane with its quarter recline uncomfortable business seats does nothing for that. It’s a small step up from economy in that you have decent legroom, but that’s it. Absolute margin at the cost of the traveller.

Good. Crew do seem to be less friendly- management are clearly limiting them or not empowering them as they used to.

The food was terrible and the seating was uncomfortable, but the airline did a great thing letting us board in Abbis Ababa on our connecting flight after our original flight was very delayed.

Delays delays making us miss or next connection to IAD hence having to stay additional 24 hrs in Addis Ababa

Checking in wasn't organized, too many so-called diplomats were jumping line while everyone was waiting in line. They should have their own line not to impede on other passengers that was also waiting to be served. We all paid money and there should be no discrimination because everyone's money should have the same value diplomat or not! If they want to give diplomats some special treatment then let them create their own check in desk and not treat other passengers some that are (elderly, some with children, pregnant women) making them stand longer in line than necessary just because people are jumping line 😡

Food hardly ever changes Videos not often updated for often travel.

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

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

The food was disappointing, and the airplane appeared old, with torn seats. Royal Air Maroc could definitely do better.

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.

Awful. Seats on this Dreamliner really uncomfortable with broken tables. No food selection availability in business class. Poor service. No engagement senior flight attendant spent more time applying make up then speaking to her guests. It appeared that the right side received a different level of service to the left when there were only 8 people. Worst flight I have ever had. A great way to ruin an outstanding two week with this return flight

Flights were okay. Not bad, not good. On time and efficient. Planes are a bit old and run down, even the 787... Casablanca airport, HORRIBLE. no air conditioning, no power outlets, no clear signs to anywhere, old, unfriendly, no restaurants to speak of. Casablanca lounge, HORRIFIC No seats available most of the time, no power outlets working, no food, only water is offered, 1 shower available, unfriendly and inneficient people, no air conditioning, flies and bugs everywhere, extremely old seats and unconfortable. Although with some cleaning crew present, toilettes are .... not too clean.

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

Wait time was very long during boarding. We had to wait a while in the bus which was under the sun.

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.

1. Boarding - Chaotic, no announcements. 2. Gate Agents - Don't care about anything. 3. Inflight - FA are good and cordial. 4. Landing - Everybody is in a rush to get out because of the crowding at immigration.
