I thought I bought the ticket directly through Kayak not a 3rd party

I like that we made it faster than regularly scheduled. Everything else was poor. The boarding was slow and chaotic. One person was screaming instructions to people that didn’t understand and there was only one camera so boarding was slow. The crew was not very friendly and one stewardess was extremely rude to everyone the entire flight. The food was not good and not themed to the country we were going to like every international flight I’ve taken. Lastly the seats were awful. After this flight I would never recommend United and will actively avoid booking another flight through them.

When I checked in, it printed two bag tags. The helper said they would cancel the other. They canceled both and my bag was left behind

It was really fast to Tokyo. Much faster than the budget carriers. However a lot less space than international flights.

The ladies are great seats should be a little bigger!

Couple of hours delayed, we had to re-booked our Shinkansen reservation twice. United Aiines need to improve their time!

The check-in started 3 minutes early; there were people lining up a half hour before. I was third, and I got checked in and passes in hand for my connection as well; I walked away from the desk one minute before it was even supposed to be open. Amazing. That said, the food on the first leg of my trip was not good, and I didn’t finish it. Second leg, it was tasty. You get a cup of Häagen-Dazs after dinner. The staff were polite and helpful. Will use again.

Crew was fantastic. Seats were not completely lay flat but still comfortable to watch a show. International food was lobster which was very big but a little tough. The scallop appetizer was delicious. Loved the individual air conditioning vent at each seat. Flight overall was very smooth and very good.

Staff was friendly but couldn't find way to track them down during flight. Food tried to be gourmet but was just too unusual. Business class seats were hard. Even sitting on the pillow, was still painful. Have to give them credit for on-time flights and decent gate area.
