There is no jumpseat privilege in any carrier in Asia (AFAIK)
The whole "commute to work or pleasure" on the J/S scenario is foreign to them
Commute to work is usually done on a confirmed (or upgradable) business class seat if you are on a commute contract and for the local guys, they get a number of passes that they can use to get on flights on their own time or simply commuting on domestic.
But occupying the jumpseat itself is only done for training and checking events.
