The flight with ANA was fantastic. Huge plane but was boarded swiftly and efficiently with a lot of crew members engaged to expedite the process. The onboard crew was polite and considerate and constantly doing things to serve passengers. The plane was new and in great working order-- definitely more spacious than the Alaska plane we took from SLC. Food was solid, not great. Lots of movie options.
