Just make sure you come to HK with a decent package including housing allowance, education and medical, and don't whore yourselves for a little low cost shiny jet.
There are two chances of Jetstar offering a package like that - one is Buckley's and the other is sweet FA.
Take a look at the threads in the East Asia forum about the J* Japan offering.
Low cost carrier - only the staff are low cost. The aeroplanes, spare bits and the fuel cost as much as they do for any other airline.
