Food was very bad Crew was not so welcoming. Chairs was so uncomfortable

The crew was great. The food was typical, but decent. Everything else - mediocre to poor. The flight was late arriving - happily for us and our 49 minute connection (what idiot came up with that?)- in another concourse - that concourse changed before we arrived (ticket and app was showing the incorrect gate - when we boarded at the correct gate - known by the airport person pushing my assistance cart). Had I walked and read the screens or United app I would have missed the flight! May other people arrived late to the correct gate, having been victims of a last minute gate change, were also relieved the flight arrived late. The aircraft (Boeing 757) was a sardine-can due to an uncomfortable seat pitch distance. The material or seat was beyond not comfortable, but I'm sure they made a lot of money with that aircraft type. I spent a lot of time standing in the back (in the middle of the night/morning to rest my back). I learned my lesson - any trans-oceanic fight - avoid United or American Airlines - and look for Airbus or Boeing 737, 767, 777. Also, pay for business class or premium coach seating.

This flight has a history of leaving late, however, I was pleasantly surprised that it was not delayed this day. The flight went smooth, except I was in a window seat and the wall and my feet were freezing. I found it difficult to sleep due to being so cold, I also was using 2 provided UAL blankets and could not get my feet warm. This was annoying, but I still made it there on time and safe.

I was very disappointed with my experience at the United Airlines baggage check. The representative was rude and unhelpful. I was required to remove approximately 1.5 pounds from my two checked bags, even though it was a very small amount over the limit. The interaction was unnecessarily unpleasant, and I expected much better customer service. I hope United will review this incident and provide additional customer service training to its staff.

Cree was organized and pleasant. Plane had good seating but as it’s a shuttle toilets hadn’t been thoroughly cleaned (eg. bins too full)

All good flight was 35 minutes early when arriving in Edinburgh

Once boarding started it was pretty quick. Food was inedible; cold and salty..

Some flight attendants were great others were cranky. Seats were very tight and sitting on an aisle was very hard as the carts and people walking constantly bumped shoulder and arm.

Why wasn't this flight departure scheduled eith another crew so that it could leave on time? When we arrived in Denver we had so little time between flights we had run to the connecting flight. We should received some credit for the inconvenience.

My flight was 3 hours late, which caused me to miss my connection in Denver. Further, this connecting flight was then Later canceled. This required me to stay another night an hour and a half away, and rent the rental car for an additional Night. I am still waiting for United Airlines to reimburse me for the inconvenience and Expense of having to extend my rental Car for An additional Day.

After boarding, the AC was shut off on the flight. At business class, I really could not breathe. I was absolutely dripping sweat. I was told by the FA that there was nothing they could do but I could stand by the door until departure. So, that's what I did. I was clearly in the way while the FAs were trying to do their work, but I had to be able to breathe. After that, of course, I had sweated up a lot so was very uncomfortable for the six hour flight.

British Airways canceled our original flight and rebooked us on Air Canada one day later. As a result, we lost one day of our Geneva trip and incurred financial losses for a prepaid hotel night and a day trip that we were unable to use.

Comfort in premium economy is worth it for long hauls especially on the 787-9P Dreamliner with the modern updates. The food was okay. All 4 of us selected the same meal, 2 of us had very dry hard to cut chicken, the other 2 were tender and good. The sides/salad/dessert all very good as far as airline food goes. Crew were very attentive. Will be hard to ever go back to regular economy!

Getting to Scotland with no luggage (no medicine, no clothes and no club) on golf trip very disappointed

Crew was great! Food sub-bar, tepid & flavorless. No snack options on trans-atlantic flight. Premium Economy seats ok, leg rest wouldn’t stay in place.

Entertainment system did not function. USB ports did not function. Wi-Fi did not function. Terrible trifecta…

Luggage did not make it onto my plane. Business seats were economy with empty row seat. Just horrible experience. Why would the company allow for transfers that don’t give employees enough time to transfer luggages??

For an long range economy flight I feel more space and more meal options need to be offered for flights over 5 hours

I had a carry on and a personal bag. I put my personal item under my seat and on way to the seat I put my bag up. I usually close my eyes and rest as I was on call for last 36 hours. I heard very loud announcements that someone needs to identify their bag. Pretty sure it was not mine until the hostess pointed out my jacket details attached to the bag. I asked why she got my bag out. I got berated and did not want to create a scene. But this person needs to be talked to.

Other than being delayed 5.5 hours and having to get a hotel because I missed my connecting flight, it was an okay flight. No in-flight Wi-Fi or entertainment.
