"SAA Step-Up Upgrade is not eligible for the following bookings: Tickets booked using promotional fares (G,W,L booking classes), redemption tickets, free tickets, tickets already upgraded using miles, and bookings with infants."
Avoid G, W and L booking classes if you want to test out this feature.
Only available on the following destinations so far:
Sao Paulo, Perth, Entebbe, Lusaka and Cape Town.
Miles will be earned for the original fare booked. So all in all, not THAT interesting except maybe for the long-haul flights.
