Good luck! My JNB flights were never delayed because of SAA going under (I don't think they're doing much rescheduling, just hanging on as long as possible?) but the rest had either been cancelled or moved and the itinerary wasn't even logical anymore haha.

Anyway, I also hope that they announce any changes in advance like they usually do! But these are also unprecedented times and they're undoubtedly hurting. So I might just try to protect myself from the risk by using the points and making prospective plans now.
