In the locked thread, it was asked "how much QF had spent on JQ".
Not sure of the total investment when including JQ Intl, JQ NZ and JQ Australia, but the investment in Asia alone is estimated at over a quarter of a billion dollars.
Qantas Stumps Up $60M
Jetstar Japan - $50M annual loss
Jetstar Asia - $4M profit
Jetstar Pacific - Not turned a profit since Qantas invested
Jetstar NZ - Not disclosed but "we in here for the long haul" - David Hall
Jetstar HK - $66M investment, but no planes flying yet
Amazing!
