The systematic shutting down of mainline, has been compounded by a complete inability to run an airline - of any sort, low cost or full service.
They are bound to end up with incorrect crewing numbers. Why should it be any different to anything else they have stuffed up.
The demise of the airline has been accelerated, but hopefully there are still a few years left in the red rat. Slowly various departments and experienced people are being removed through VR. No doubt some needed a little push from their empires, but it is quite scary to think that some of the key areas are going. Therefore it is unlikely there will ever be any growth within QANTAS again.
