Flight delayed and then cancelled (due to mechanical issues + weather). Poor communication. No one there to help with rebooking and accommodations for the night we had to stay in Newark. Our luggage was taken off the original flight and apparently left on the tarmac in the rain. Items were soaking rain. The following day, the flight was also delayed due to mechanical issues. The second year in a row that I had to sleep in an airport flying from Tokyo to Newark due to mechanical issues compounded by bad weather. Partly bad luck and partly just poor service.

Polaris seat is plush and conducive to sleep. Cabin crew was experienced, highly attentive and helpful when any need arose, such as finding a lost phone in the seat mechanism. Food was a disappointment, especially the Japanese items coming out of Newark all seemed a bit overcooked, though the empanada snacks served midway were a hit.

Staff on the plane was incredible. Check-in was very complicated with no staff to help at the airport. I was charged for a second bag even though my ticket says 2 bags are free

Our flight gor canceled and there was no one to help us but told us to scan the qr code and fill the forms on-line. Very poor service especially we are tourists traveling to Washington DC for the 1st time.

Flight was delayed 5 hours. Updates kept changing. Sears were extremely cramped. Very little leg room. Flight attendant was rushing through with drinks and hit me in the knee either the cart and didn’t apologize. They gave a 15 dollar voucher in airport which doesn’t buy. Much and it was so late that choices were limited.

I bought this ticket for my daughter. She had to pay for her carry on bag to be checked. My understanding is that transatlantic flights included carry on and personal item The nickeling and diming fo legacy carriers has stooped to an all time low. So sad.

It's fine but Newark to Nashville was too long

The flight was delayed because they closed several flight ways because of air shows, fire works, etc.

I was exhausted from a long day. The flight was smooth. The first flight during my 3 week travel that took off on time.

Crew was amazing, takeoff wonderful. The bathroom was disgusting from before takeoff the odor made the flight uncomfortable as you could smell the bathroom from the center of the plane where we were sitting. Smelled like raw sewage. My daughter was throwing up as we landed due to the smell and horrible turbulence as we approached Newark.

Spacious and clean aircraft. Good food. Economy will always be squeezed but thankfully I had an aisle seat for stretching exercises. Good selection of movies, particularly Spike Lee joint.

Unfriendly, 8 hours delayed, no lounge access even flying business. Don’t fly Brussels

On board service was decent. I like the legroom at UA that seems to be more than in other airlines

It was really good because the employees were very nice and fun to talk to. The entertainment was nice because they had plenty of movies to watch.

The flight went well, only during the flight from Brussels to Vilnius I would have liked if they had at least given us plain water to drink.

The crew and the flight were excellent, the food might be better!

This was absolutely one of the worst experiences of my life. I came to Europe for a 2 week trip and the airline was probably the most disorganized airline I’ve ever seen in my life. They lost my luggage. I had tracking on it for just such an occasion and told them EXACTLY where it was in the terminal and they somehow failed to get it out on the flight that night, since we were leaving for Switzerland the next day there was no way they would get it to our hotel in time. Seriously, take another airline at any cost. It’s not worth whatever you pay…you’ll end up paying a lot more in the end. My medication is in the bag and I can’t get to it and don’t know how I will get it.

I missed my connecting flight due to long lines at security and immigration. Need improvements

Food quality is deteriorating each time, last year was very good. I avoid the plane food lately.

I felt the overall quality of the plane and food service was less than that of their partner airlines, United. An example was wine was served in paper cups in premium economy class. There was no real silverware, napkins or a welcome kit other than a pillow and blanket.

The seat was wet when I came in. Food was just something. And during a whole 11 to 12 hours in the airplane NO WIFI. Was is the point to buy a business ticket if you can be connected to your relatives and your company. Ethiopian used to do that to theirs customers, TECHNICAL ISSUE, WE ARE SORRY….. I am a gold customer for ET. It is very disappointed!

It was a great experience for my first time flying with this airline. I will be flying with them a lot more now. Plane crew was amazing.

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

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

I paid for internet that did not work and had to pay more to have it

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

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

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

Terrible customer service I lost my bag luggage and I still haven’t received any information

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