My flight was delayed so bad i missed u it so i just said never mind

My flight was delayed so bad i missed u it so i just said never mind

Delayed 2 hours while stuck on the aircraft. If the luggage was properly loaded the first time we probably wouldn’t have been delayed at all

1. Everything was satisfactory concerning the flight. 2. Can't think of what could be better right now.

Onboard staff was courteous, helpful, responsive and friendly. The boarding process was disorganized, poorly communicated, and disheveled. Gate agents were yelling instead of using the PA system, didn’t communicate the timing delay of our flight, and created an atmosphere of chaos rather than order and communication. As far as I know, there was no reason for their. I would hate to see how it operated under extreme conditions. I’ve never seen United Airlines operations in such a state.

The flight did not have its customary snacks during the flight. Apparently they were never loaded on the plane.

Worst service- attendants dont want to help and sat us in front of bathroom

We sat on the hot plane for ours with very conflicting messages. Some (most?) of this may be due to the flight control staff, but we were also repeatedly getting "we are leaving"/"we are not" messages. It was very uncomfortable

Staff could’ve been a little more cordial. The men were much more friendlier than the women. My daughter and I also missed the 2nd to last meal as we were sleeping but that is on us.

Like: departed and arrived on time. Unlike: Food options for purchase allways bad, 1 of 2 of the crew members not very friendly at all. Seats and leg room aweful. At this point I am thinking on switching to AA.

Our flight was canceled same day and we were never informed. Had to pay more and worse seating on another airline.

WE didint profit of food , but for the other think all was good

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.

How can a national carrier and part of Lufthansa group not even provide complimentary water and a snack in such a long flight ?

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

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.

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.

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

United was best airlines I have seen since I got there choose united airlines

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

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.

Very bad experience flight was over 5 hours delayed 😑 not a chance to be put on another flight we had to stay at the hotel we lost 2 days on our vacation. Never again I will fligh with Ethiopian airlines.

Boarding was delayed and people were just sitting there like lost.

Movie channels was great. Air hostess could be a little more caring

We missed our connection and they put us in a hotel our luggage didn't get rerouted with us so we arrived with no luggage

The crew was friendly, 5/5 stars. The food was better than ok, 3.5/5 stars. The seats were tight, 3/5 stars. The entertainment was 2/5 stars because of lack of WiFi.

ldid not like the late departure did not like the late food service. Food should have been serve earlier ro allow more sleeping time. Did not like beeing interrupted just to show announcement about their duty free onboard Finally baggage did not make it to final destination and are still in casablanca.

My luggage was left behind in Miami. I wasn’t the only one. I couldn’t get a boarding pass from air Maroc but I got one from American Airlines for the air Maroc leg. I had the sense of getting in line with air Maroc boarding crew and showed them my AA boarding pass for air Maroc and I got a new one from them. There were several passengers filing missing bags reports in Casablanca so I assume there isn’t a good coordination between airlines. My AA bag ticket says Casablanca but it is from AA. I wasn’t the only one missing a bag.

I couldn’t find my boarding pass with the information provided by Underpricer. It took me several hours to find what the issue was. Finally I got the right code to get my boarding pass from American Airlines. Underpricer WhatsApp call center finally got it right. When I got to Casablanca my luggage was left in Miami. Not sure which airline fault it was if Air Maroc or AA. I filled out a report with Air Maroc

I would like to praise one of the stewards, Mohamed, who was swift and efficient to help me as I was not feeling well at some point during the flight.

Improve food quality and clean the seat . Bathrooms not clean

Stay away at all cost! Late boarding, late departure, inoperable seat controls and entertainment screens, very rude cabin crew,

3 hour delay, very rude flight attendant the food was horrible.

Plane is dirty Food quality poor Service was not good Lounge extremely bad
