I'm not that frequent of a traveler, but I can say that I have never encountered a problem while traveling in and out of Saint Louis. This airport is not going to make any Top Ten lists, but it gets you where you need to go. Parking has also never been a problem here. We use the Parking Spot, and have always received fairly good service while parking and being transported to the terminal. If you want to cut out some hassle, I recommend flying Southwest, which has it's own terminal for the most part.
