The Aseana Air ground crew & in-flight staff were very professional & efficient yet pleasantly helpful & accommodating. Although it is no Changi airport, Narita has so many shops & restaurants to help kill lay over time .Bring power banks as the charging ports are far few & constantly clogged.

Maybe don’t sit in the center aisles for such a long flight. No way to lay your head to the side when sleeping

I like the landing which is nice and safe, seats are also comfortable

Staff on board were good - food was fine tasted good - tv was old 1970ts in seat back but hey it was a 2 out flight so no drama

Lost suite case and pillow that’s used by senior and they didn’t leave it at the airport

I had a comfortable seat that makes my trip wonderful. I appreciate the Ethiopia crew, they were very helpful

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.

It was wonderful best Air lines covert and all very happy with their service they have been very helpful and friendly

For Vegetarian Food was very poor. Though we had opted for Asian Vegetarian Food they didn’t serve but only what was available was served. We were offered Smoked Salmon!

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

Flight was delayed an hour. Also, I bought an extra legroom seat online; but the actually plane was a different configuration so I didn't get what I paid for . This happened on the Addis to Lusaka leg of my trip.

Needs improvement because some of the tvs and charging ports weren’t working

My experience was great. The flight attendants were very helpful and nice, and the food was very good.

Quite ordinary, as might be expected of a budget flight. It was difficult to understand the instructions unless one speaks Japanese, and the seats were quite basic.

Very easy process overall. The staff communicated well and everything was efficient.

Very affordable, smooth check in process, flight attendants were safe and kind, lots of flight availability within Japan.

The seat is so bad Can’t recline the chair

For Travelers with babies, if they can be supported by allowing to carry the Baby stroller upto the Airplane gate, and not submit at the Check-In counter. it will be very convenient. Thankyou.

I didn’t even fly on it can I get my refund
