Better management of the boarding process. Is there any way you could forward all the window seats first? That's the Way Reno Air used to do it, and they had the fastest boarding in the industry!

Old plane, no amenities. Very abrupt landing. Unnecessarily long taxi time.

Good food and entertainment. Poor choices for drinks. Sitting for 12 hours on the row by the restrooms, which do not recline, was a torture

Legroom in Economy was fair to good. Seat was omay; I was hit in the shoulder twice by the cart as it was being whisked through the aisle. Overhead space was good for my carryon. Lighting environment was nice

The flight was for my mom in wheelchair the staff in Newark wer not friendly took a long time to even get a wheelchair she almost missed her flight because they finally got a chair few minutes before boarding they had to rush her to the gate. They took her carryon and checked it as a bag told her don’t worry free of charge but they charge the credit card anyway. She also told me the seats are not comfortable at all as if they were broken she could feel the bars in the seat SFO staff was much better overall she had the worst experience

Wifi is very frustrating - could not connect and therefore unable to work on the trip

Entertainment was great. Seats were good. They did not have my pre-ordered hot food product available but did comp me something cold in place of the item.

Sitting on the runway after we land for almost two hours! Not sure if we should blame United or Just Dumpy Vance.

Please please take consideration when setting cabin temperature. The vents were not functional and it was over 70 degrees in the cabin during the winter months when most people are used to much cooler indoor temperatures. I was down to my white t-shirt and the sweat pants I wore from Auckland to San Francisco and was sweating profusely and there was NO VENT!
