had their flight to HKG
a while back, there was a LOT of fanfare. It had a special route designation, lots of dignitaries were invited, and lots of souvenirs were handed out. Someone told me that the plane carried both the Japanese and Hong Kong Flags.
Rumor floating around was that one of the Japanese Royal Family members was in First Class but I'm not sure about that one
route had a number of similar happenings, like souvenirs, photos taken, special signs at both terminals, water cannon salutes, etc.
