It is probably one of the oldest airplanes crossing the Pacific, and the oldest business class still operating. (DFW-NRT)
I like the Cole Haan amenities bag, food is surprisingly good. Lie flat seat is, again, old but okay, but things around you are not very practical. (Compartments / drink holder / writing space / small objects storage etc.)
Still, what makes a good flight is: landing safe.
And after one more flight from Tokyo, hello Hong Kong, I am here!
