Seems like a regular thing. I was thinking about going to SCL but looks like LANPASS miles require you to book a roundtrip. I liked the idea about doing SCL->IPC->PPT and then back to the States but it looks not possible anymore: LANPASS is roundtrip only and BA shows 0 availability for the next year on any direction.
Seems the only good use for that visa is upgrade coupons or a roundtrip flight to places like Punta Arenas...
