The gate was too far away for the connecting flight

Compared with other carriers business class for an overnight was not worth the extra expense.

Seats were comfortable. It’s was so cold and very uncomfortable. I paid 2000 miles for wifi service that was choppy the whole flight. Would like to be reimbursed for my miles Food was so disappointing. Three cold and terrible meals for $3000 round trip. This needs to be better.

Easy to board. Flight was super crowded though so I didn't sleep well on that cross country red-eye flight. The aisles seem ot have gotten narrower and the seat smaller whn luggage and people are getting bigger so it would be AWESOME to have more space and breathing room in general ;)

Pilot Erika DeLong made us feel safe and at ease in a frankly scary time to be flying. Her warm smile and greeting and excellent command of the aircraft in foggy bumpy weather helped us all to calm our nerves and get us home safely.

Plenty of room for me and the cat in Premium Economy. Seat was comfortable. Boarding was a breeze. The lady at the special check-in desk was great, super helpful and professional.

Smooth flight. As always dinner could have been more generous. Breakfast was great.

AWFUL. I have had the experience of traveling with many airlines across the world, and hands down United Airlines is the worst. Not one flight was on time, and I don’t think I met one crew member or staff member who wasn’t rude.

Old and out of date plane, it seem like every time I fly with united there’s and issue. We were delayed,
