i checked the schedule of china airline
they changed to 747 during early Feb (chinese new year) temporarily.
guess they get good business for this holidy destination.
my question is that they used to use A300 or A330 and sold two-cabin service only on this route.
So what to do with those extra F seats?
do they just keep these F seats empty or some C passengers get luck?

(if this way, wish i am the chosen one hehe)
