Don't think the TAAG B772's are an option, because SAA Technical does not have the staff or equipment to facilitate B772 schedule maintenance.
Should TAAG do it on SAA's behalf the TAAG ban will be applicable on SAA(B772).
Think SAA will look for A330, A342/A343 or maybe even A346's. The rumour around is that SAA could not cancel the A320 order and will have to take them.
