Staff was so nice and very helpful with directions aswell!

Not great, will likely try to fly another or maybe I should have upgraded my ticket? Needed Air…

I don’t think I’ll be flying them again. Tight seats, no flowing air or air nozzles that you can turn air on you, for those who could have motion sickness this would be your worst nightmare. The pilot was great and experienced (which is what you want when flying 12 hours) overall I’m thankful knowledgeable pilots!

My ticket did not indication which group I was in for boarding; the gate attended help me

staff are super nice and effiecient! It was a very comfortable and relaxing flight

When I booked a premium economy ticket. I then had to pay $100+ to book my seat.

Boarding could have been a little bit better but other than that it was a pretty good experience. I think because of the stowaway to Paris France recently they are being extra diligent about boarding passes at the gate. But they boarded the back of the plane first, and that's something I really think needs to start in the USA.

I did not take the flight, tried to cancel it right after I booked it, but was unable to reach anyone. I blame Kayak for this situation because they sent the booking through another company and I was unable to get anyone to talk to me about the situation. I had to just take the hit and pay for another flight through Cathay Pacific, which was wonderful. I will never use Kayak again. (I bet they don’t post this review!) I’ll just post about them on social media sites. I don’t want anyone to have to go through the hassle and expense I dealt with.

Airline itself is great. While food was being taken off of my tray my beer spilled which was a total accident and I wasn’t upset about that, what was frustrating was I had to ask for towels to clean up and wipe my leg. It would have been left as is if I hadn’t.

The food was the only thing that could have made the experience even better. Everything was stellar but the food. The staff was superb. I’ve been flying with ANA for years as my go-to and I think I may have found my new favorite. 😍

Liked fold flat bed. Didn’t like having no window. Didn’t like poor choice of food and being served dinner very late, hours after take off of a 7:40pm flight. Servers not friendly. Food horrible in business class.

Everything is good except the dinner and breakfast. The sandwich is very delicious. Toilet is clean, I only use one of them. Flight attendants are very nice. 👍👍

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.
