Jetstar is only "sound" due to significant subsidy from QF. It couldn't, and wouldn't exist if it weren't for big (read - soon to be smaller) brother.
The theories you state are only valid if you believe the financials that QF spout. And if you do believe them, then I've got a bridge you might like to buy.
Simple fact of the matter is that QF is currently all about deception. It is smoke and mirrors. There are things happenning in the background, and faceless men with ulterior motives.
Don't believe all you read, crystal.
