I have plans to go back to Australia next year and have been searching for options to make a side trip to Port Moresby in Papua New Guinea. So far I assumed QantasLink and Jetconnect are not Oneworld members – and therefore merely bookable with Qantas Points (which in turn is a Citi ThankYou Points Transfer Partner).
QantasLink flies from Cairns (CNS) to Port Moresby (POM) – which is just a 521 mile journey.
However it seems British Airways Executive Club IS able to book teh flights when you clal in. They do not show up online but the quick journey should only cost 4,500 Avios.
QantasLink also serves a lot of destinations in Australia incl. Tasmania.
