The Southwest Airlines STL Terminal is one of my favorite places to travel. It's not too crowded and is tidy and orderly. There are no long lineups at TSA, and the check-in process is quick. Good eating options are available, including local fare, and there are no lengthy walks because the gates are close to one another. I usually get on my flights on schedule, and boarding is easy. Here, Southwest performs a fantastic job! visit : https://www.terminalfind.com/southwest-airlines/southwest-airlines-stl-terminal-st-louis-lambert-international-airport/
