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.

It was a short flight so, everything went smoothly and we got to where we needed to be safely.

Didnt make it on flight. Flight was delayed. Then had to get rebooked for a flight that was 8 hours later. Guess who had to wait for 8 hours at the airport?

The Air Canada AC1 flight from Toronto to Tokyo on May 16 was great overall. Service, crew, food and entertainment were all excellent and everything ran smoothly. We had emergency exit seats so legroom was amazing, but the seats themselves weren’t very comfortable and the plane feels like it could use an upgrade for a long-haul flight. Aside from that, everything else was perfect.

The plane was very cramped to point there was no way not to touch person beside you and a stewardess screamed at my son when I touched her arm to get her attention to let her know she forgot to give him his dinner when she passed him and gave a dinner to passenger behind him. Very inappropriate response and She never came back to apologize and other stewardess said she was sorry “if I felt” she was inappropriate. Horrible experience and she should be reprimanded for her behavior

Everything went smoothly — on-time departure and very organized boarding. We pre-ordered vegan meals, which were fine but not especially memorable. We may have had slightly higher expectations given it was a Japanese airline. It felt like a dinner meal than a breakfast. Overall, it was a good flight experience and we would recommend it.

The last 3 hours it was freezing cold in row 56. Multiple people had their winter coats on and were utilizing the blankets provided by the airline. I also did not have easy access to figure out how to book my food allergy and advance for my meals. Most of everything I received was something I couldn't eat. This needs to be made more accessible. Also, I'm 5'10 which is the average height of the American male. I flew from Philadelphia to Toronto and then to Tokyo and the seats were absolutely unbearable. For that long of a flight it is impossible to get comfortable when doing anything. Flights need to have more space and stop prioritizing costs over people.

Was delayed at every point/ connection. Luggages missing for 5days. Had no medications for diabetes and high B/p. when bags where finally delivered on the 30th, the insulin and ozempic were no longer patent, as the ice pack had since dissolved and the authenticity of the med is now questionable, since they must be refrigerated. Please have them refund my bag fees. I should sue them for all the inconveniences caused to me.

This flight with a lot empty place , and I have more room, feeling comfortable.

Snacks were just placed and many people were hungry and unaware they were available. Ran out of water bottles. Attendants not available. Missed entire meal.

The cabin crew was professional and there were plenty of movie choices, but the food was a bit sub-standard.
