What Molokai suggested is something you all should strive for; I understand some Chinese airlines are actually moving towards USD20K with the understanding that the greenback is going to trend lower in the next few more years.
Commuting 6/2 will only work well if you are operating to your home base; for those who are going to be holed up in PEK, SHA or CAN for 6 weeks operating Chinese domestic flights and international sorties not to their homes, it will be a route to mental depression and family breakups. What recruitment agencies should convince their customer airlines is the need to bring Chinese airline T & C's to international norms practiced by good legacy carriers as China moves into a major role on the global stage.
In present practice, medical and life insurance issues are the recruitment agencies' call and so are sign on/end of contract bonuses.
