Probabl for flying NRT-SYD on QF or JL and connecting to LA to SCL. All the Oneworld partners have apromotion at the moment if you fly on the FFP's "home" carrier and connect with another Oneworld carrier. I think on Aadvantage it has to be a round-trip itinerary but on QFF and obviously Lanpass one-way is good enough. Number of bonus miles/kms/points also vary with each FFP
