Don't wanna turn this into a full on review, but flew TPAC for the first time ever last week YVR-HND-GMP and back. What a great experience.

HND was modern and super fast to clear customs and get my bags.

GMP on the other hand was a bit run down and slower but still wasn't anything like arriving at IAH behind a few flights or at YYZ behind a few widebodies.

Honestly my biggest complaint about ANA was the 767 YVR-HND, it's clearly way too old to be flying this route, the AVOD is kinda terrible and when I saw the J class seats didn't lay flat I was shocked (I was in Y though haha). The aircraft to/from YVR had lots of open seats so maybe they don't see the demand to put a higher priced product, but it would've made sense for me to see at least a 2 class aircraft with lay flats since it's a 10:40 flight and overnight on the return.

If given the opportunity to fly ANA again, I'll jump at it and even more so if I can connect/disembark at HND. Got into Tokyo at my friends place in no time with an easy metro system.
