Jetstar Domestic Cabin Crew retain the Career Progression Agreement under the EBA. Under an AWA, who knows? Doubtful, as the CPA is an industrial agreement between Qantas and the FAAA.
Jetstar International Cabin Crew will not have any access to Career Progression to Qantas Short Haul.
Qantas Short Haul are expanding through Regional Flying, as is Jetstar. Since 2004, two intakes of Jetstar crew have transferred across to Qantas Short Haul.
