“In terms of fuel hedging, we hedge with Qantas, so we do it completely together. There's no point, Jetstar is 100% owned subsiduary owned by Qantas doing something that would completely counteract what Qantas is doing, which is largely a cash flow issue, its about mitagating potential losses through fuel or currency hedging so it would be silly for us, given we pool our cash together and we operate a common treasury function to be out in the market doing something completely counter to Qantas”
