Anyone had any experience booking awards between Australia and South America?
Checking AA, BA and QF, there's about as much Business Class award space (for two people) on QF27 (SYD/SCL) for almost all of May - Jul 2015 as there are hookers in the Vatican City (and for one person, you'd be lucky to find anything anyway - QF PE, on the other hand, isn't all that bad).
Checking the QF website, there's availability on the LA flight, but QF gives the availability under its codeshare flight number (QF321). If I search for the same seats on BA, there is no availability. This suggests to me that there's probably nil chance of picking these up (I'd book and try but have no definite dates yet, just scoping).
If I can't get to South America directly over the Pacific, I can only see this happening by either trying via DOH (as someone else has ambitiously set out to do), or via North America (e.g. via LAX or DFW, both push the PN MPM to South America, assuming US DM will allow the use of that indicator).
