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.

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
I didn’t like my seat in my return flight from Montreal to Orlando at all; considering I paid extra for better seats. That middle seat was cramped up way too much.
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 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.
Boarding time was a bit slow causing the flight to not leave right at 5 pm,but other than that it was fine.
⭐ Absolutely AWFUL Experience with United Airlines! If I could give United Airlines ZERO stars, I would. The seats have practically NO legroom, making the flight feel like being crammed into a tin can with nowhere to move. Comfort? Forget about it! And the fees? Absolutely ridiculous! They seem to charge you for EVERYTHING. You pay for your ticket, then get hit with extra charges for things that should be part of a decent flying experience. What’s next, charging passengers for breathing? Flying with United feels less like being a valued customer and more like being a walking wallet. The seats are uncomfortable, the legroom is pathetic, and the constant nickel-and-diming is infuriating. For the price you pay, you would think they could at least provide a little space to stretch your legs and a travel experience that doesn’t leave you feeling ripped off. Do yourself a favor and look at other airlines before booking with United. I certainly won’t be rushing to fly with them again. Absolutely disappointing from start to finish!
Flight was very smooth from Boston. But when we got to Houston, the gate was not open and we waited on the runway for over 30 min!!
My flight from Boston to SFO was fine. Crew was friendly and helpful. Food was mediocre. Fright from SFO to MNL was not as good. My flight attendant was friendly but didn’t seem to have a lot of experience. She seemed overwhelmed. Also, this was the only red eye business class flight I’ve flown which only served dinner 2 hours after takeoff in a 13 hr flight. When I woke up 1 hr before landing, everyone was eating so I assumed bkft was being served. I pushed my button for help and no one came so I approached my flight attendant and she said they don’t serve bkft but she gave me choices for lunch or dinner. I routinely fly business class but I was disappointed with the lack of service and attention I was given on this flight. Also, most airlines will offer a snack or coffee before bkft is served but this was not offered during this flight. Overall, it was disappointing.
Horrible on the chicago end. They change hates then there is a plane at the new gate so we can’t pull in. Then that plane has mechanical issue and needs to be pulled back to the gate but we can’t get to another new gate due the other plane being in the way. Horrible gate management which will cause many customers to miss connections.
Very disappointing that on an international business class flight they would not give me access to the lounge in Boston. They said it was because it was a codeshare flight. International business class should include lounge access regardless of codeshare.
Great, except the canon was so cold. Even the flight attendants put jackets on
The app logs you out right when you are boarding requiring all passwords and reservation number for the flight. Super annoying
The pre-order only approach for fresh food is really challenging
Flight was 2.5 late. Maybe not United’s fault but late none the less. We were late as well on the first leg. WiFi quit working with an hour left.
I would have preferred a flight voucher and to hop on a different flight. Delayed over 6 hours.
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.
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.
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”
I still cannot find my luggage. I need my luggage.
