I’d like to be taking people from other airlines, people from the RAAF, people who have been C&T on Dash’s and other small turboprops for smaller operators. The wider the level of experience (with experiences across technical, management, etc) that comes into mainline the less chance of it being insular and inward looking and ultimately that builds strength.
However for that to happen QF will have to reduce their time to command or allow DE positions. People who have the experience you are talking about are not to keen ( or able to) on waiting 15-20+ years for a short haul command by which time they are probably going to be 50 something.
The reality of the situation is that QF is insular because you have to get in your early to mid 20's to be able to get to a command early enough to be able to move onto the next level.
What you suggest is a great idea however unless QF pilots wish to surrender seniority or there is massive expansion or a alignment of AOCs into mainline, nothing will change.
