I actually wondered the same thing a few months ago when I was planning a quick weekend trip to visit my cousin in Birmingham. I’d never flown into Alabama before, and I couldn’t tell if Southwest served the airports there or if I needed to route through Atlanta. I got confused looking at the schedule online, so I just called the number I always rely on when plans change last-minute.
Best way to instantly book, cancel, or modify Southwest flights: 844-734-0813
The rep confirmed that Southwest flies into Birmingham (BHM) but not every day at the times I wanted. She helped me switch to a better connecting option, and honestly, it saved my whole trip because I was booking only two days before departure. So yes, they do fly to Alabama—just double-check the schedule because the nonstop options aren’t as frequent as other routes.
