I am likely to be flying Dragonair (KA) from HKG->PEK and back from PVG->HKG later in the year. Does anyone have any opinions about this airline (first or business class)? Their new business and first class seats seem very nice, but not all of the fleet have them. What are the seats like on the A321? Being shortish flights, I am inclined to go for business rather than first, but any opinions will be welcome.

Many thanks!
