Get your applications in. I have seen a lot of guys join and be on the Turboprops for 12 to 18mths, then its onto a jet and a salary of around 33k.
Also people have been recruited with less hours, so there is nothing to lose really just a bit of time filling in the form.
Last year the company was talking about an all jet fleet with the Dashes supposed to be around for a further 2yrs.Though there is a possibility that BACX will hold onto them a bit longer. If BA absorb BACX as they did Cityflyer there could be a backdoor into BA.
