Yes, Jetstar NZ is profitable. Costs of $24.3M with income of $26.8M equals a profit of $2.5M. However the source of income for Jetstar NZ is Jetstar Australia ie. JQ AU pays JQ NZ for labour costs + 10% which is then paid back as profit.
As far as the JQ NZ operation being profitable for the QF group, who knows...
I don't think anyone is wishing anyone else out of a job, but questioning the management that might end in everyone being out of a job is probably appropriate.
If the business case of being the cheapest in the market to make the most money was the right one, then surely the results should be coming in by now...
