Ok, so why don't JQ own their aircraft instead of leasing them, if they want to maximise their profits? And why does QF mainline own A320s (which they don't even operate) which they then lease to Jetstar? Considering they are both part of the same group, wouldn't it be more efficient for Jetstar to own the aircraft themselves, cut out the middle man and save on the extra costs associated with setting up the leasing arrangement?
I think Virgin, Tiger, Easyjet, Ryanair all operating lease much of their fleet. Don't know why JQ lease some from QF, could be tax related or maybe they are intending to sell to an operating lease company at some point in future.
