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

For a long haul flight, the seats were too narrow. Paid for extra legroom but wish I could have paid for width! I was pressed against another person for the whole donation of the flight.

Delayed flight made my day very long, but other than that KQ got me to my destination in good shape.

The nice treatment and lovely pilots who accepted my son inside for a photo.So lovely of them

Got delayed for over 24 hours. Fight was cancelled. Was put up at a nice hotel whose kitchen was unfortunately not prepared for the sudden influx of guests The headphone jacks on the seat were loose and sound kept getting dropped over the headphones. Food was good though. Certain items (Amarula) were not available for purchase over the on-plane duty free. Had been told i would pick my luggage at my final destination*wrong* had to pick it up in JFK and recheck it and then got charged for it**** too tired to argue with the Delta staff on the issue.... after a 15 hr flight.

This one is not bad even it is late, but they apologize and every time they announced the update.

I’m very disappointed for this trip and I will never travel again in this airline. In addition, I don’t recommend to any human being to travel to Kenya Airways. They keep me at Nairobi for 4 days without care. I was at Nairobi from 6 a.m Morning up to 10 a:m Thursday. For that reason, I have trouble for my work and may be I will lose my job. During for those 4 days I didn’t have my medicine, I didn’t have clothes to change because all my clothes were in my checked bags. On Thursday, when I got flight, they don’t even apologize for all consequences I had. During for those 4 days, I learned many things for this airline. It is their system to treat passengers like this because they had hundreds or thousands passengers around Nairobi waiting for their flights after their original flights cancelled. If I lose my job, I planned to file claim to the airline. This is not airline to travel with.

They weight duty free goods at check in and count the weight as carry on luggage. Results : for 4 bottles I had to opay $150. rip off. Be careful to avoid any duty free shopping at Dubai airport

The boarding was fast, the food was great; however, the seats & leg space were tight.

I enjoyed my flight I arrived safe with all my luggage

No complaints just improve on the food service. Provide enough dinner. People are complaining about that.

There was no food !! We ordered Kosher and they confirmed they would have it but the crew told us that kosher food was “out of stock” We went hungry for 7-8 hours

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

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.
