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.

My experience with the united usually is a really good one. But however, on this particular trip going back to Hawaii from Manila, our flight had gotten canceled. However, the crew handled everything just right, but the Specialist team did not take care of their first class customers very well, Because I lost my first class seat and witch I'd paid for $3879.79 and ened up flying.... Economy on the way back and I have a medical condition to ware i cant sit in Economy seats for very long....And I have to fly first class for a reason, but they told me there was nothing they could do about it. But yet they have an itinerary to follow And It looks to me like they just let anybody grab those first class seats before they took care of the people that have already paid for them!! So when a flight is canceled, they should take care of their first class ticket payers... First because we pay big money for those seats And we count on those accommodations in those benefits... For real good reasons, that's why we pay that kind of money. I'm expecting at least half of A. Refund back to my credit card for you for this...And if I don't get it, I'll never fly united again, it's sad that this happens And some things are out of our control, and I totally understand it, but at least handle your first class holders first before all.. That is what we pay for.

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.
