I heard that you need 1000TT and turboprop time will be advantage. Some ex CAP 509 guys have got in with a few hundred hours. I think an ICAO licence will be acceptable but I don't know what licence they prefer, if any. I didn't know that CX had a online application form. I thought they did things the traditional way?
Remember that the current atmosphere at CX for new joiners is less than 'cosy' due to the IFALPA recruitment ban that is in force. I have seen a copy of the standard letter sent from the HK Aircrew Officers Association that is sent out to new joiners and it is worrying reading! The word 'scab' is mentioned and elaborated upon in a rather strong context!
