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

Need to do a lot of improvement on service and cleaness

Our first flight was delayed and when we got off that plane, nobody was really helping to direct us to the next gate. It was very frustrating. One staff simply said hurry, which wasn’t helpful. We had to go a long way to get to the next gate. Another issue on the plane itself was the bathrooms were disgusting and filthy and it didn’t seem like anybody was checking on them were cleaning them and it was a long flight. There was urine on the floor and they stunk. Also, the screen in front of my seat did not work, and I tried different headphones and still had no sound. You would think somehow those things are reviewed occasionally for working order.

They only gave us 30 minutes to make an international connecting flight. We didn’t make the connection but they did do a good job rebooking us despite the chaos. Our bags didn’t make it back and their process for customer support is pretty bad when it comes to luggage.

My recent experience with ASKY Airlines was disappointing. The check-in process was disorganized, and I was provided with inaccurate information regarding baggage requirements, resulting in unforeseen expenses. Additionally, the ground staff demonstrated a lack of professionalism and appeared insufficiently trained to handle passenger needs effectively. Regrettably, this initial encounter has left me reluctant to consider future travel with the airline.

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.

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

Traveling with Ethiopian is always a good experience. I also enjoy the stay at skylight hotel in Addis

Lost suite case and pillow that’s used by senior and they didn’t leave it at the airport

Forgotten Suite inside of the top compartment but went back to ask and they didn’t leave at the lost and found place. Also the checking in was so horrible. I had multi city and one of the passenger saint have visa go go go Dubai. The Ethiopian airlines never had information about requirement for US permanent resident so couldn’t go to Dubai. And when coming back to US we were told we can not use our Addis to Washington ticket and they forced us to get new ticket. Very horrible experience.

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.
