If it is an FO job at SQ then I guess the biggest thing to think about is does he want to be an FO at SQ or join the cadet scheme here at CX as you said he is deciding between CX or SQ. So FO at SQ or 12 months learning to fly in adelaide then 4 years as an SO with CX with no housing! Don't understand what there is to consider as CX are NOT hiring FOs.
