My connecting flight from CTS to Narita was late and I missed my connection. A very nice agent met me when I deplaned and ensured that I caught the next flight back to SFO. Fantastic customer service :)

My connecting flight from CTS to Narita was late and I missed my connection. A very nice agent met me when I deplaned and ensured that I caught the next flight back to SFO. Fantastic customer service :)

Cabin Crew was excellent. They took care of everything requested. Flight was good

I didn’t know that my connecting flight from Japan to Hawaii was at a different airport - arrived in Haneda (ticket said Tokyo but didn’t notice the airport name) and had to get my bags and go out of immigration and back in to go to Narita airport 2 hours away. Such a hassle and SOOO confusing and complicated. Check your airports IN ADVANCE and NEVER book if you have to change airports. 40+ years of flying and first time had this. Never again. ANA is great but booking agencies will sell you a connection that you have a good chance of missing - even under the best circumstances.

I was charged $200 for a 2nd checked bag, which is unreasonably high and feels like price gouging. Other than that the experience was excellent.

The ROOM was great. We would love to have it on all of our flights. LOL

I would prefer to fly with Japanese airlines over American ones. They have better food and service overall

I was too late to get onto this flight. Kayak shouldn't let you book a connecting international to domestic flight when flying ANA. Your domestic flight could be in a different terminal and you won't make it because you have to go through immigration and customs.

United Airlines crew members do not know how to deal with emergency situation that caused our flight delay. For example, they should have asked the maintenance or seat belt repair personnel to come and fix the seat belt while they were looking for a volunteer to book another flight.

I always take ANA because of the great service and overall experience.

Tokyo Haneda to transport was so bad too short time . and find out way to the gate was so bad. I almost missed flight. because confused. They need more great way tell us how to get there details
