Looking at some of the alliance timetables (Star, Oneworld, Skyteam), I noticed how far your FFP miles can carry you on the network of your airlines' alliance network. Before I get flamed: what I mean by "exotic" in this context are places that don't see many flights at all, or that don't have many international connections, and are basically beyond airlines' or anyone else's beaten path.
Star Alliance: Yuyhno-Sakhalinsk on Sakhalin Island in Far Eastern Russia (Asiana), Boa Vista in the Amazon Jungle (Varig)
Oneworld: Falkland Islands, Easter Island (both LAN)
Skyteam: Ulan Batoor (Korean), Antananarivo/Madagascar (Air France)
Any others you can think of? Which are the far flung corners of alliances' networks?
