About QF taking guys within the group from Qlink and JQ..... yes probably a few but they won't empty the place out especially now that they are desperately short on crew. That is the reason I left after 8 years, because I knew that Q400 skipper is the best you will ever get and I got that impression within the first month. Period. If they had a pathway in place to QF I never would have left.
And you can bet your arse that plenty of experienced VA 737 drivers will be applying for QF for the job security alone. No one is sure VA will still be around 5 years from now. We had a few guys in NZ turn down commands and go to Air NZ, speaks volumes!!
