Now I may be wrong, but I believe airlines can still file fares that have ticketing restrictions that are country specific. It isn't called SITI anymore, but they can still restrict the point of sale if they want to. And apparantly SA/RG have done just that, with higher C fares if it is sold outside of ZA/BR/AR. Unfortunately I can't offer a solution...
