Agree with mrben on the timing of applications.
Agree with smallwing about the money. Wannabes should not be too concerned about that, particularly in HK, they do very well and only have to look at some of the starting salaries in Europe or the US to appreciate how lucky they are to earn that kind of $$ with so little expreience.
I'd fly for anyone regardless of money, as long as I could survive!
Why do you think it is a bad idea to apply for them at the same time smallwing? I would have though it would show even more motivation to get flying.
Just my 2c
