I think that DECs will be most unlikely. The transition to the A320 has proven there is no need.
On a brighter note - one would think Air NZ F/Os would be up for command a little sooner perhaps over the next few years, with lots of retirements at the top end etc.
Will the re-organisation of the fleet affect this - better prospects or worse ?
Any idea how long it will now take for an Air NZ F/O to be eligible for upgrade ? It used to be years............
But that could change hopefully in the future.
Any ideas ?
