The TV wasn't working No music for the whole flight from JFK to LOS It was too burring.

Flight was delayed by two hours. This really messed things up because I missed my connecting flight in Addis. I had a meeting in Entebbe which was scrapped because my flight from Addis landed later in the day.

To the Ethiopian Airlines Customer Relations Team, I am writing to formally express my disappointment regarding my recent travel experience with Ethiopian Airlines on . 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 paid for internet that did not work and had to pay more to have it

We had a good flight experience with this airline despite reading many negative comments

The crew was unfriendly and very rude to name a few (Helina). I felt unsafe due to most of the cabinets were open while on flight. All in all the flight was ok, but the crew needed more training on customer service most of all for international flights.

The plane was ok, I was in business class and was surprised there were no pods and each seat was right next to another one. That said it was comfortable and the food and coffee were good. Entertainment wise again I was surprised to see only movies and no TV shows. Check-in at Toronto Pearson was an absolute disaster, which was especially disappointing as I was a business class passenger. There was no dedicated staffing for the business counter and four (4) airlines employees assisted one economy class passenger for about 15 minutes when one could have easily assisted me. Overall room for improvement, particularly in the on-ground experience and airplane infrastructure.

Delay not posted, only departure time listed- not boarding time. We left an hour late and arrived 45 min late. Restrooms had backed up sinks and toilets not flushed ) passenger error). Lots of screen for entertainment didn’t work. But we arrived with our luggage

The plane was old and the luggage racks above us were visibly shaking during turbulence. Water was dripping on our heads during landing. Our flight was over 2 hours late departing but we were not updated or told what to expect as the screen at the gate continued to read “on time”
