Is SAA even fiying right now???
 

I cancelled my trip from the USA to Africa in August 2020.

My SAA flight from LVI to JNB on 25 August, and my SAA flight from JNB to TRN on 27 August are still showing active on SAA's website and google.com/flights

I thought SAA cancelled all of there international flights, or is SAA still flying within the African continent?

SA borders are currently closed except for repatriation/evacuation flights, SAA have operated some in May/June and might operate more in July.
Domestic flights are allowed since 1st of June but AFAIK SAA did not resume those either.

While they may have not (yet) cancelled their scheduled flights for August, I think it's very unlikely they will operate.
