I liked that it was a short flight and that the over-head bins were big enough for my backpack.

I didn't like that my friends, who bought their tickets at the same time I did, with their own cards and checked in at the same time as me, didn't get a seat number. I had one assigned when my ticket printed out, after I checked in at the airport after they did. They had to wait until boarding was almost complete before they were afforded a seat. Seemed really strange. With United already having a bad name from recent stories on the news, it made us worry. Don't like worrying when it has anything to do with an airplane.

The way the upper back and headrest of the seat was shaped made it very hard to be comfortable when sleeping (this was a red eye flight I took, so the entire flight was sleeping). The lighting in the cabin was also not as dim as I've seen on other flights that are clearly overnight flights - it was much too bright.

Nothing at all!!! That should really tell you something!

The staff were rude, abrasive, ignored several passengers that were trying to get her attention before take off as 2 overhead bins were wide open and full to the brim. She of course was too busy playing on her cell phone in the back of the plane and ignored/silenced the passenger call button. They were so loud when people were sleeping, yelling ‘trash please’ every 5 minutes, we are not stupid, we can see what you are doing and if we have trash, we will give it to you - so please STOP disturbing my peace and let me bloody sleep!!!! I was never offered any food or drink during the entire flight, not even when I was awake - other airline attendants are more observant and come back and ask us when we are awake if we would like anything to eat or drink. So essentially that was 7 hours with nothing after having paid a little over $700 for what was seemingly the WORST transatlantic flight I’ve ever taken. I travel back and forth often, because I’m a dual national, but I will stick to BA or Virgin Atlantic - the planes and service are far superior to this pile of turd that goes by the name of United. There were no charging facilities (power outlet or USB port) and the TVs had such horrendous resolution that you would get a headache from having to squint at the screen.

Once the aisle/window seat, cabing luggage, food/drink is paid for, the price is very close to standard rate.
