St. Louis Lambert International Airport's Terminal 2 is home to Southwest Airlines. For Southwest flights, this terminal provides travelers with quick check-in counters, Southwest Airlines STL Terminal  ticketing services, and baggage claim spaces. It mostly handles domestic flights. To improve their pre-flight experience, travelers can find facilities like Wi-Fi, food alternatives, and retail stores. Because Terminal 2 is typically less crowded than the main terminal, Southwest travelers should aim to arrive at least 90 minutes before to their planned departure to provide enough time for check-in and TSA security inspections. For qualified travelers, Terminal 2 also offers TSA PreCheck, which speeds up and simplifies the security procedure.
