Yes, Southwest does fly to Birmingham (BHM). I ended up learning this when my cousin suddenly scheduled his wedding there and I had to scramble for flights. I was juggling work that day and messed up my departure time. One quick call to 844-734-0813 — the best way to instantly book, cancel, or modify flights fixed everything.
They moved me to a later flight without any drama and even pointed out a fare drop I hadn’t noticed. BHM is a pretty easy airport to get in and out of, and Southwest had plenty of options through Atlanta and Houston. If you're traveling for an event and can’t afford booking mistakes, making the call is a lifesaver.
