I'm looking at BOS-EZE-IPC-SYD-HNL-LAX-BOS for this coming winter and with stopovers in each city. Routing to BA doesn't matter, whether by NYC, MIA (even though most everyone here says don't) or DFW, or even on LAN via Lima or Santiago de Chile from JFK or Miami as we wouldn't want to stop over anywhere except maybe Lima to see Machu Picchu.

Easter Island's the kicker and absent an award we'd never go there, but it seems we can. But then what? I see flights shown on QF's route map from Papeete to SYD via AKL (but as a codeshare on Air Tahiti Nui) and the LAN flight to Easter Island continues to Papeete as well. Can I route IPC on LAN to PPT then QF PPT-AKL-SYD? Is Air Tahiti Nui a OW partner? - it's an AAdvantage partner but I can't tell if that matters for OW award purposes. Or is having a QF codeshare number sufficient? It doesn't - far as I can see - show up as a QF "affiliate" on the OW page.

Otherwise it's back to SCL and change planes there for LAN/QF service to Australia via Auckland. Do they count the miles used flying back to Santiago toward the award mileage limit? And would southbound routing via Lima (and hence Santiago en route to BA on LAN) put us over the limit on transfers at SCL? - as we'd be there, transiting - three times in that scenario

Never done this, finally made EXP, and now looking to burn up some miles while I am/can. Any advice would be appreciated.
