I've only flown through STL once and from what I recall it was pretty small and all of the Southwest gates are close together. For those of you that are familiar with STL, is that true? I'm taking my dd to see her dad next Friday in Chicago, and the flight back to BHM has a 30 minute layover in STL. I've personally never experienced such a short time to change planes when flying Southwest and I fly them monthly! BTW, it will only be me (with no luggage) flying back. Oh, and it is the last flight of the evening to BHM.
