Welcome to market economics the hard way, lads.
Australian aviation is now learning what the rest of the world has known for some time. You can all say goodbye to the Qantas of old, it's a dinosaur anyway and could never survive in that form. Like it or not, Jetstar and it's ilk are the way of the future, and no amount of breast-beating will change that.
You'd better all learn to adapt...
BTW not suggesting that this is a good thing, it isn't, but it is the new reality.
