Hi there... I have been planning a trip due to commence in July 05 originating from HKG... any advice/comments would be greatly be appreaciated!!!

HKG>CNS>DRW>AYE>SYD>SCL>LIM>SCL>EZE>LHR>HKG.

Aside from the actual routing, I was just wondering if RTW tickets could be exempt from the RT policy of upgrading flights (i.e. apart from CX flights, no OW ugs)... (eg BA EZE>LHR) using ASIAMILES? I mean c'mon how can RTW flights be RTs anyway? (Unless you constantly backtrack!!!)

Thanks in advance for any suggestions...
