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

Check in took over an hour because printer was not working. Attendant did not know how to give free layover Addis Ababa hotel vouchers or update frequent flyer number. After repeated attempts, got voucher emailed. However hotel wanted printed voucher hence more delay. Bus time from hotel back to airport was printed 4:50 hours, but hotel reception called at 3 pm saying bus will leave at 4 pm. Then hotel reception called again saying 4:15 pm. We rushed at 4:15 pm and bus was not ready until 4:40 pm. Many audio outlets were not working in planes.

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!

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.

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

It was very bad experience with Ethiopian airlines . The flight was delayed in both ways . On the way coming back one of the crews dropped hot coffee on my whole body and other crew dropped used dirty glasses on top of me . The same crew that dropped hot coffee on me hit me with the food trolley on my knee while I was sleeping . I couldn’t sit properly due to the pain on my knee caused by those irresponsible crews . Very unprofessional 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.

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.

I had pre booked gluten free as a meal preference. Nothing of that was considered during my flight. The attendant said he had no idea and would check but never returned with a response. I did not eat anything that flight and was super hungry

Stay away at all cost! Late boarding, late departure, inoperable seat controls and entertainment screens, very rude cabin crew,

The flight itself was fine. The flight was delayed for nearly 10 hours and there was inconsistent communication about why it was delayed.

My luggage did not arrive yet, it been 4 days without any information

They had everyone line up for boarding and then made us stand there for 30 minutes

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.
