Here's a question about the unspoken pre-requisites that maybe only someone already on the course can answer.
If you're an older person, and I am, but you're not married and don't have any children, is that likely to severely disadvantage you as it does in the wider world of business?
Someone might also suggest what kind of flying interest and enthusiasm you need to display? From the Cathay application website it looks like they're only interested in all round wing commanders, or at least expect you to be a member of every aviation and flying club within fifty miles.
