Once again Deskjockey is 100% accurate:
Alec Irwin has made it very clear (at the last meeting between SAA and his department) that the recent capital bailout was the last. His words were to the effect that the SA taxpayer will tolerate no more.
SAA will certainly end up as a more productive, streamline and competitive airline than the one we know now. I suspect that much of the domestic market currently served by SAA will end up being operated by either Mango or SAX (the money ends up in the same coffer after all).
