it's a MPM fare and you can hop around South Africa, Namibia and Zimbabwe , I had 600 odd BA TPs, You can also route through JNB twice for some really creative ones like the below, 2 stopovers free each direction too but remember JNB to GRU needs a Yellow Fever Cert!!
Excellent for seeing parts of Africa that are normally cost prohibitive,
Ignore the dates below this is just to give you some ideas
