I just priced up this basic DONE4 out of JNB and wanted to get the collective wisdom on the charges, especially the carrier fines. Since they are lumped in, it is rather difficult to ascertain where they are coming from. I shudder to think what including BA might do to such an itinerary.

Base fare: 59,010ZAR
Carrier fees: 11,790ZAR
Taxes: 2,499ZAR
Total: 73,298ZAR
