IB/OW- LAX-MAD-JNB $896 21,700+ miles
 

Seems to price and be bookable for scattered dates through early next year at least. Sizeable layover in MAD, haven't tried to play with the routing.

Can also be had with AA/BA on the outbound for just over $900

Not an IB expert, but a pretty cheap way to get to S Africa.

Edited to add- Looks like good through May, and also works for other AA US hub cities, some for even less & on AA and BA metal. NYC, ORD, DFW all seem to have dates.

And I actually thought that was a Business Class deal :) Shows how much fares have come down....
