Yes, if you're paying in US$. The exchange rate USD/ZAR had softened since April, making ex-SA tickets more expensive (in $) than they had been, ignoring any price increase for the ticket. However, the US$ exchange rate is now back where it was in April, so that element has been cancelled out.

OTOH, if your 'base' currency is, say, GBP or EUR, an ex-SA ticket is now a fair bit more expensive, on exchange rate alone, than it was even a month ago.

This is the wonderful world of Forex. If you didn't buy at the right time (or did buy at the wrong time), don't be too discouraged. Apparently, even major corporations get this wrong all the time.
