It can all change with one good CEO.
I think it needs a big clean out of the board as well. There is no way the QANTAS group will get out of this situation without a massive change at the top. The whole company is just toxic at the moment, it needs a culture change, and that starts at the top.
It's also not just Mainline that is in trouble here, it's the "Group", if you think your safe at Jetstar, Network, Qantaslink etc, you probably need to take a bit more interest in what's going on here, because if the "group" runs out of money everyone feels the pain.
