HI, If you have A319/320 PIC, I think you should apply for the mother airline: Shenzhen Airlines. They need Captains for their 319/320.
I think age limit to start working is 57 or 60
but not sure at all, and there are always exceptions.
Go to
www.wasinc.net and check and highlights of the contract and apply there too, I dont think they charge 45USD for application right now.
I have some friends their and they love it. day trips, great money......oh and very very cheap to live there.
Good luck.
