Airlines F-in with people

Why can I get a flight from Corpus to Birmingham AL for $363 that changes planes in Atlanta. But if I want to take that same flight JUST to Atlanta they want to charge me $566?  ITS THE SAME FLIGHT NUMBER!!!!!!!!!!

They've always done that.  When I was interviewing, here in Florida, I lived in Columbia, SC.  A flight from Columbia to Orlando via Charlotte was less than flying on the exact same flight from Charlotte to Orlando.
