Southwest Airlines Check-In at STL
Southwest Airlines is known for its unique and customer-friendly check-in process. Unlike many other carriers, Southwest does not assign seats at the time of booking. Instead, it uses a boarding group system that allows passengers to board based on their check-in time. This system can create a more relaxed atmosphere at the airport, but it’s still important to know how the check-in process works.
Online Check-In
Southwest Airlines encourages passengers to check in online before arriving at the airport. The online check-in window opens 24 hours before departure, and it’s a good idea to check in as soon as possible to secure a better boarding position. Southwest’s online check-in process is quick and easy, allowing travelers to select their boarding group, add additional services like early bird check-in (which guarantees a better boarding position), and even download a mobile boarding pass to their phone.
Self-Service Kiosks
For those who prefer to check in at the airport, Southwest offers self-service kiosks located throughout Terminal 2. These kiosks are user-friendly and allow passengers to check in, print boarding passes, and even check bags. The kiosks are equipped with touchscreens, and the process typically takes just a few minutes. Passengers can also use the kiosks to add baggage or upgrade their flight options.
Baggage Check
Southwest Airlines has a generous baggage policy, allowing passengers to check two bags free of charge. This is one of the airline’s key selling points and is especially appreciated by travelers who need to bring more luggage on their trips. At Terminal 2, Southwest has dedicated baggage drop counters where passengers can check their luggage after completing the check-in process. The staff is typically efficient, and the process is straightforward.
Customer Service Desk
If you encounter any issues during check-in or need assistance, Southwest Airlines has a customer service desk located in Terminal 2. The friendly staff can help with various requests, including seat assignments, special accommodations, flight changes, and rebooking in case of delays or cancellations. The customer service desk is also available to address any lost or damaged baggage claims.
Security and TSA at STL
Once check-in is complete, passengers will need to pass through security before heading to their departure gate. St. Louis Lambert International Airport is known for its efficient security screening process, thanks to the streamlined TSA operations. Southwest Airlines passengers departing from Terminal 2 will use the security checkpoint located in the center of the terminal.
TSA PreCheck
For frequent flyers, TSA PreCheck is available at STL, allowing for expedited security screening. TSA PreCheck participants can enjoy shorter lines and keep their shoes, belts, and light jackets on during the screening process. If you’re a Southwest Airlines customer who holds TSA PreCheck, make sure your Known Traveler Number (KTN) is added to your reservation to take advantage of this perk.
Security Process
The security process at STL is standard for major airports, with passengers required to pass through body scanners and send their carry-on bags through X-ray machines. Keep in mind that certain items like liquids, gels, and sharp objects are restricted in carry-on bags, so it’s important to review TSA guidelines before arriving at the airport.
