Qantas has been quoting NZ Domestic passengers and Australian Domestic passengers who travel internally on a flight with a JQ International flight number as JQ International passengers.
Jetstar International didn't carry 358,000 people in and out of Australia in January, they carried 195,000.
Jetstar International are not the third largest International Airline operating in and out of Australia.
Jetstar International didn't grow 100% since January 2009, most if not all that growth came from their replacement of Qantas NZ with Jetstar Domestic NZ, and then quoting those domestic passengers as Jetstar International Passengers.
