Airline reviews

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 [I629/352] . 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 paid for internet that did not work and had to pay more to have it

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.

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”

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.

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.

Delays delays making us miss or next connection to IAD hence having to stay additional 24 hrs in Addis Ababa

Food hardly ever changes Videos not often updated for often travel.

The flight is packed and it feels like the space per individual has gotten smaller. Excruciating for a 14hr flight.
