I worked on the Hartsfield Airport expansion project in the late 70s.
Southwest
was the only carrier I saw flying DC-3 passenger planes into Atlanta
(there were
a few cargo carriers using them).

Those two companies are not the same. The present day Southwest
Airlines has only flown Boeing 737s. Southwest Airways was the DC-3
operator you remember:

The DC3 thing sound strange to me too. I remember mixing with SW's
737s operating out of Dallas Love. At that time, I thought they flew an
extremely limited set of routes that did not reach the SE US or anywhere
else outside of the SW.
