The A319 is not as fuel efficient as the C Series so if QF does order them, it's probably because they need to reallocate some of the massive A320 order to avoid penalty payments. So again, Kelpie seems to be on the money.
PS Mustangranch, it appears that your anger at Air NZ causes you to ignore the years of raping & pillaging that News Corp carried out at Ansett prior to Air NZ buying into Ansett. They are guilty of not doing proper "Due Diligence" because if they had, they would have discovered just how serious a basket case Ansett had become at the hands of News Corp (who paid 100% of the CEO's salary).
