AJ will not be revisiting shutting down the airline again. He has used 8 lives with that gag.
Should the airline start to fade away, the emergency laws should be invoked, QANTAS taken over by the government, and the board removed for reckless behaviour and charged as such (but we know that will never happen) and keep the airline in government hands and never be held to ransom ever again by a bunch of greedy individuals.
