American Airlines - Last one standing

AA last one standing? There are many others that qualify for major status but AA isn't the only legacy that hasn't filed. What about Continental?

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:
