Sorry I wasn't clear about that earlier... For either South Africa or South America, the stopover in London would be great. I figured it was allowable for South Africa since that's a somewhat logical routing. Wasn't sure about South America since there are other Oneworld options to get there without routing through Europe.
A 2-for-1 J award offer is pretty insane. Does BA do that often?
Reminds me... One of these years, I'm going to try to make it to Comrade's Marathon. And we have family in the UK... So maybe the South Africa trip with a British stopover could come in handy for me as well...
