All Nippon Airways

Flew ANA to Hong Kong by way of Narita. The NRT-​HKG route is serviced by Air Japan which is a branch of ANA. Interestingly, the other routes between Japan and Hong Kong are operated under the ANA brand. I could not tell what difference (if any) there was to the main line. The plane had the ANA livery, so it did not seem like anything was different.
This route uses Boeing 767 planes. I took the Dreamliner for my flights between Seattle and Narita and I found the 767 much more comfortable. It is a larger plane with more seating in all classes. The only noticeable difference is the entertainment system had less options to choose from. But perfectly acceptable for a 3+ hours flight.
I thought the seating and seat pitch was better. Though I could not recline since I was in one of the seats next to the lavatory on both flights. Cabin ventilation also was good. It did not feel too stuffy or cold. And they give you a blanket to keep warm.
They serve one meal during the flight. I chose the Japanese option on both flights which was great. Flying with ANA, you can expect their Japanese fare to be delicious. Chicken karaage and grilled saba were my choices. Both were tasty and they came with equally good side dishes including cold noodles with sauce. Also you can order alcoholic drinks like beer, wine and spirits with your meal. Even in economy!
I enjoyed my flights to and from Hong Kong on ANA. I liked it better than the ones I took on the Dreamliner between Seattle and Narita. The good food and service along with the comfortable seating on the 767 are reasons why I would consider taking ANA again if flying to Hong Kong and Asia in general.
