I just tried to book a trip, changing the original CPT-DOH to CPT-JNB-DOH-BUD (you can't book on the tool if QR first). I had priced a similar itinerary, CPT-LHR-BUD, also BA as initial carrier, and it was 80,000ZAR. Leaving London out brought the price to 73,723ZAR. So I put in all my travel information, went to pay and got a message "We are unable to confirm the fare for the flights you have selected. Please choose a different fare or flights and resubmit your request".

I think this is where you would have called Mindpearl with your flights. Maybe I'd get a new guy?? I think the consensus is to try to ticket through BA office in JNB--correct? Any other ideas? This is discouraging.
