VAA and VAI based in Australia on Australian T&C's
VANZ based in NZ on NZ T&C's.
Different country, different management, different conditions.
Is Jetconnect on QANTAS seniority list? Can they transfer to QANTAS Australia? I think VANZ are lucky to be on the list at all, based on the facts above.
The problem with allowing VANZ pilots to use the 2008 date, is that it will displace too many pilots from VAA, pilots that have already been displaced by VAI. Considering 60 VANZ pilots applied for 6 VAA 737 f/o positions recently, it gives you an indication of their intentions.
As for the threats for future flying.
If they get A330's good luck to them, they can brag about being the lowest paid A330 pilots in the World.
