Too cramped up for the better seats I paid for.

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 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.

Were not told that carryon laggage has to be only 12 kgs but my bag was heavier asked to pay an additional $550.00. I could have upgraded to a bussiness class for that price and no one at the gate to upgrade but able to take money for the extra weight. I felt like this was a setup scam.

The hygiene was super bad. Smells bad and air refreshment is highly advisable. The crew made some one else sit in my spot and no one is checking seat number and people are jumping to sit on other people’s allocated seat.

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.

Im if Ethiopian can allow customers to use their mileage for in flight connexion it will be great.

United was best airlines I have seen since I got there choose united airlines

The plane was overbooked and the crew was very rude. My luggage was never put on the plane. I got to NY and waited 2 hours just to find out that my luggage was left.

Very bad experience flight was over 5 hours delayed 😑 not a chance to be put on another flight we had to stay at the hotel we lost 2 days on our vacation. Never again I will fligh with Ethiopian airlines.

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.

I felt all of the food tasted the same. And we had five meals over the 16 hrs in the air.

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.

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.
