Never let the facts get in the way of a good story.
As far as a race to the bottom is concerned try doing some research, it is actually more expensive for the operation to be crewed by Jetstar pilots.
As for parallels with the QF Singapore base(which I am lead to believe hasn't been knocked on the head yet) Jetstar pilot in NZ will end up being paid more than those in Aust.
But hay its a good story so you guys stick with.
