So Upgrade now!
And upgrade guys with in the company .Why not. Put all together and start assessments for upgrade 5-4-3-2-1 yrs with the company. Give preference for guys who were captains before maybe.Do something ,but don't hire DECs because QR dont need them now.and the time for upgrade guys current flying A330 or A320 as FO will be faster.
Why hire Decs who gonna be unable to bare with the place? As captain is hard to bare with.As first officer terrible,but at least the guy has a dream to upgrade and he gonna stay for while.
