It could also be the reason the A330 training for base maint. has been slow. They knew that they will have a few more in base soon from heavy.
A330 A checks are to start in base soon.
Did any apprentices get Heavy as a final section? Don't know of any getting base, a few got shoved into cabin.
This could be a run of changes that could see QANTAS not actually have any employees in a few years time. A shelf company that leases some planes.
