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

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.

Flight was excellent. Transfer from one airport to another airport for a connecting flight was difficult and stressful.

Overall good except the checkin process at Bangkok airport. Can ANA explain why the line for business class is longer than that for economy? I, BC passenger, had to move from BC line to economy line to get faster service.

Matsuyama to Tokyo is basically a puddle jumper flight, so it was as good as one should expect. No meal, no entertainment, and none expected.

The staff is amazing, I cannot stress that enough! The food is really good and snacks at stations to take for yourselves. Economy seating is fine, not the most comfortable, but our friends in Premium Economy said they were very comfortable! Decent entertainment options, but being built in, you have to use their cheap headsets unless you have your own plug in ones. I only have Bluetooth earbuds.
