Airlines like ANZ love the seniority system...it’s going nowhere fast so relax.
A plan agreed to by the unions will pass, where to minimise costs the 320 pilots will still fly the 320 but a bit of seat shuffling will/may occur. No wide body pilots are going anywhere for a while...so use up that leave, go drive a truck if you have to. All this training talk nonsense is just that...until the world starts spinning again.
The company has an idea of number of pilots required on the other side. There will still be the usual destinations and excessive redundancies are counterproductive to this plan. Once a new international flying program is developed there will be downward movements but why/how can they form decisions regarding crewing allocations at the moment. It’s a mugs game. This is highly unsettling times. ANZ has taken decisive action, and compromises will still be required before the status quo recommences...and it will.
All the very best.
