The tactic used by the QF Group execs seemed to be to try to answer as many questions as possible with excessive verbiage or detail to either confuse the senators (which I don't think would have been very hard) or to reveal the true "difficulties" facing them.
The two things they were talking about here were "P&L" - profit and loss - versus cash flow. What Evans was saying was that the routes still being flown by QF International are cash flow positive (meaning the flights are making money), but that QF International are doing badly on profit and loss. So, by extrapolation, the flights are making some profit, but not enough to counter the losses that are being made elsewhere - maintenance costs or labour costs, by inference. What the senators weren't cluey enough to ask was where QF International was losing money and whether Jetstar cost-shifting was taking place.
Personally, I would love the Senate Committee to recommend to Parliament that a forensic audit be conducted on the QF accounts prior to a decision being made as to whether assistance should be offered!
