I checked Dragonair web site for several date conmbinations.
DEEEEEEP discount fare (O/N) can be booked HKG-KHH-HKG.
However, next lower fare seems to be L.
So, probably, no published fare of V for HKG-KHH-HKG.
If you try to book HKG-KHH one way, only booking class Y shows up.
Furthremore, if you don't satisfy minimum stay requirement for L class, you can not purchase a ticket. Then, advanced purchase requirement has to be satisfied if applicable.
If you fly from BKK, I can find
BKK-HKG-KHH-HKG-BKK
V class (9500THB,3M), L class(11000THB,3M). M(12000THB,6M), K(14800THB,1Y)
So, you can book V class for HKG-KHH segment, However you have to find FARE !
