The boarding experience did not follow the Zones that were listed on the boarding passes. This was a two-level aircraft with many passengers. Because zones were not called out by the airline staff, there was simply a mob trying to board and it was not a pleasant experience.

The boarding experience did not follow the Zones that were listed on the boarding passes. This was a two-level aircraft with many passengers. Because zones were not called out by the airline staff, there was simply a mob trying to board and it was not a pleasant experience.

All great, because I was given a seat with extra legroom on this part of my trip.

Plane was good Crew was good Food was just ok Could have had more entertainment options But overall good

Paid $10 for wifi for full flight duration and the wifi wasn’t available after initial 2 hours

I was unable to pre purchase sear upgrades or internet. Their online site is not user friendly and poor. I felt singled out in customs. Seats are very small even for a small person.

Staff was very friendly. There is no on board entertainment, but it’s such a short flight that it doesn’t matter. We also got a meal which was nice and unexpected due to the length of the flight.

I had first class service from them. A little late taking off, but no major problem

Not good. Expected a lot more as far as excellence.

Was required to print a boarding pass, which I'd prefer to avoid. Seat (economy x) was comfortable, service was excellent.

Very bad. We booked 8 months in advance for 2 people but couldn’t get seats together. Food was so bad I couldn’t even eat.

Customer service was poor everywhere. In particular in business class lounge. Stewardess were however excellent. No ability to order more than one dietary restriction in food that created awkward situations when I was offered bulgur due to being diabetic as I was also gluten free

My flight was canceled 1 minute before boarding. The customer service was owful, no one could tell us what was going happened. I spent 30hrs instead of 15 from Washington DC to Brussels. No apologie or help

I really enjoyed the food, only bad part on one of my flights my screen was a bit buggy but it wasn't a big deal it was one of their older planes so I understand that happens

The segment bkk ist was ok. The segment ist to yul the boarding was chaotic with 5 control before get in the plain, in addition to normal control by scanner and metal detector during transfert

In sharp contrast to the modern glitzy airport, boarding facilities were primitive. Passengers had to board buses and walk up steep stairs in bitter cold with carry-on baggages. I found no reason why aerobridge was not provided.

Very good, it took a little too long for the food to come out on a service that left after midnight but everything was great.

Business class in Turkish airlines is like none other. They separate themselves and highly recommend it

I will avoid this airline as much as possible. Service was rude, and I don’t think the crew knew how to answer a CALL LIGHT. I pushed my call light on the ohare to Istanbul and the Istanbul to Thailand flight because I was very very thirsty. NO ONE CAME. I pushed it twice! NO ONE CAME! Why have a call light when no one will come? My experience was the WORSE AND I WILL NEVER EVER FLY WITH THIS AIRLINE AGAIN. The cabin crew needs to learn MANNERS AND BE RETRAINED on their jobs on how to be helpful and kind instead of being short with their customers and ANSWER CALL LIGHTS! I honestly wouldn’t be suprised this airline goes out of business.

Flight attendants were harsh, food could be better, took way too long to pick up food trays, were stuck with the crying babies the entire to and from trip. Restrictions of 8 kg for cabin luggage is ridiculous that’s barely 2 pairs of pants, shirts, shoes. There shouldn’t be any restrictions on the carry on luggage size except the checked in luggage. Attendants don’t even help with putting luggage in cabin space. Attendant picked up food tray and spilled cherry juice all over my husband and has the nerve to come back to ask why he hadn’t changed his clothes.

Business Class Service was unacceptable. 7 flight time changes and delays

The flight was very smooth, however, the quality of food was mediocre.

To the Ethiopian Airlines Customer Relations Team, I am writing to formally express my disappointment regarding my recent travel experience with Ethiopian Airlines on flight 629/352. Unfortunately, the level of service provided fell significantly short of the standards I expected from your airline. I would like to highlight the following serious issues encountered during the journey: • Cabin Condition and Hygiene: The aircraft cabin was notably poorly maintained. The seating area was dirty, and there was a persistent, unpleasant odor throughout the flight, which made the environment very uncomfortable for passengers. • Inadequate Service: The overall level of service provided by the staff was unsatisfactory and did not reflect a professional passenger experience. • Baggage Loss: Upon arrival, I was informed that my luggage was lost. This is particularly distressing as it has caused significant personal inconvenience and disruption to my schedule. As a frequent traveler, I value reliability and a clean cabin environment. I request that you investigate these matters immediately, provide an update on the status of my missing baggage, and outline how you intend to compensate for these failures in service. I look forward to your prompt response and a resolution to my lost luggage claim. Sincerely, Puguh

I will fly this going forward especially for ORD to EBB and the reverse.

I had a memorable experience. I dont have any comments at this time regarding waht could be better.

The food was terrible and the seating was uncomfortable, but the airline did a great thing letting us board in Abbis Ababa on our connecting flight after our original flight was very delayed.

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.

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

Like: Plane made it to the destination. Dislike: Food is terrible, no entertainment, very dirty airplane.

I had a full row so can't imagine how this could be better

Food was horrible. Our flight was not comfortable due to turbulence, seats was not comfortable, Very tight barely can not move anywhere.
