Jetstar expects to unveil its new range of low-cost international fares in the next few weeks and has promised it will pull out all stops to promote them.

The airline says it is still on track for a November operational launch and it expects to have fares considerably below those currently available.

Jetstar spokesman Simon Wetaway said the airline was in the final throes of getting the traffic rights to operate its start-up network.

He said it already had the rights from the Australian end but was working through the process of obtaining permission at the other end.

The airline had an experienced team working on regulatory approval with the Civil Aviation Safety Authority. There were agreed timelines in place and while the airline did not want to pre-empt the regulator's decision, it believed the program was on track.

This included approval to operate its twin-engined Airbus aircraft up to 180 minutes flying time from the nearest airport.

"We're also working through our commercial systems to ensure we're in a position to go ahead to market as has been our wont and our reputation in the past," he said. Jetstar International would initially offer cheap flights to Bali, Bangkok, Honolulu, the Thai island of Phuket, Ho Chi Minh City in Vietnam and Osaka in Japan.

It is working closely with Singapore-based Qantas investment Jetstar Asia and its domestic arm to establish the brand as the Qantas Group's second major airline arm.

The airline expects to have three 303-seat Airbus A330-200 aircraft flying by Christmas, and will initially focus on outbound tourists.

It plans to have six A330s operating by the middle of next year, bringing the number of jobs created to 550, and to move to 12 aircraft when new Boeing 787s begin arriving from August 2008. And if all goes well, Jetstar could be flying to Europe and the US by 2011-12.

However, Mr Westaway said the airline had no immediate plans to launch international services from Avalon Airport, near Geelong.

Avalon's owner, transport magnate Lindsay Fox, told the Geelong Advertiser last week that he wanted to attract international flights from destinations within 12 hours of the Victorian airport.

Jetstar currently operates international services to Christchurch from Melbourne Airport and its new long-haul services would fly to Honolulu, Bali and Bangkok from Tullamarine.
