As stated elsewhere, approx 55-60% of the quoted Jetstar international traffic is PURELY DOMESTIC traffic in Australia and primarily NZ.
In addition, the NZ numbers are highly suspect because NZ publishes no passenger number details. Crosschecks of the Jetstar NZ schedules incorporating a seat count if every flight and a comparison with the quoted load factor reveal a substantial discrepancy, something Jetstar have been queried about but have failed to explain. It is more than fishy.
