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 was really good because the employees were very nice and fun to talk to. The entertainment was nice because they had plenty of movies to watch.

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

That was a short flight by the only time I could actually sleep

How can a national carrier and part of Lufthansa group not even provide complimentary water and a snack in such a long flight ?

The flight went well, only during the flight from Brussels to Vilnius I would have liked if they had at least given us plain water to drink.

i send you separate claim of what happens ,I buy ticketed from you and you said that it is confirmed and shall send the ticket in 24 hrs but you did not send and when we go to Ethiopian air line counter they say it is pending and we dont know why ,and we forced to buy another ticket ,and this all because Ethiopian air lines canceled the return flight from Adi Ababa to Amman, please note that we buy all the tickets through your app and hold you responsible for all loss and discomfort.

No Asian Vegetarian food was available on this sector but only fish and chicken and pasta were offered.

Flight was delayed an hour. Also, I bought an extra legroom seat online; but the actually plane was a different configuration so I didn't get what I paid for . This happened on the Addis to Lusaka leg of my trip.

Needs improvement because some of the tvs and charging ports weren’t working

Terrible customer service I lost my bag luggage and I still haven’t received any information

The ailine departed and arrived late foe every leg of the trip, causing myself and my travel companions to miss every connecting flight. It was very unorganized given theat there was a lot of miscommunication. The flights offered are unrealistic and when you call they assure you that the plane waits for you. I missed an. entire day of my vacation and any entire day of rest back home because of the airline. I do not plan to support the airline again. Thank you

I liked nothing of Ethiopian airlines except the price of the fare.

The use of a domestic carrier without entertainment was disappointing and a let down

Plane was late with no information or announcement … had to walk up n downstairs.., had not communicated this … and ppl had suitcase to carry .

Like: It arrived, Dislike: Boarding was a separate corridor with no counter announcements at the passenger waiting area. Very dirty airplane and toilets, food options were terrible - everything even the vegetarian option was a curry spice. Many other passengers using the toilets would not lock the door and kept door partially open during use - flight attendants would not enforce or direct them to lock it and light turns on, no entertainment options at all, other passengers would be singing and not peaceful. Atrocious flight experience.

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.

This is the worst seat that I ever sat on. The length and width are great but Super uncomfortable. We felt like sitting on marble.

Worst flight experience of my life. It was cancelled and they left us in the airport for 7 hours having no idea what to do.

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.
