I was the beneficiary of that mistake. Once BA figured it out, they fixed it by requiring that all *ONE* tix issued at MRU now be reviewed by the BA London RTW desk before issuance, so I haven't been able to repeat my good fortune. You may want to have a look at purchasing the ticket at JNB or CPT. Due to the sharp decline of the Rand, I believe that you'll find that AONE* tix issued in S.A. are now less costly than those from MRU. You will, of course, still be subject to the same itinerary limitations as if you purchased at MRU.

Good luck, and enjoy. There's nothing like traveling around the world in F!!! I start my fourth in two years a week from today.
