Home Forums Hunting & Shooting Africa Delta Computer/Flight Problems

I am headed to Windhoek Thursday. Schedule looks like this:
DAL to ATL--Delta
ATL-JNB--Delta 200

Here's the rub. In light of Delta's computer shutdown Monday, there have been numerous cancellations and delays at Delta. I am concerned about the DAL to ATL leg,as they cancelled that flight on today's schedule for some reason. Obviously if I miss that one, no connection for ATL to JNB is possible.

Question: If I have to take a Southwest flight from Dal to ATL to make the connection, instead of the Delta flight from DAL to ATL, will my reservation for flight 200 ATL-JNB still be valid, even though I'm not on the DAL-ATL leg?

Just trying to consider options at this point.
