Arrivals, departures, and getting around STL
- Departures are usually upstairs. Most STL terminals put ticketing, bag drop, and security on the upper (departures) level, with baggage claim and pickup below.
- Follow your gate, not just your terminal. Inside security, signs point you to gate numbers and concourses — your boarding pass lists both.
- Accessibility. Elevators, accessible restrooms, and wheelchair assistance are available throughout; ask your airline ahead of time, or look for TSA Cares if you need extra help at screening.
- Picking someone up? Head to baggage claim on the arrivals level — but to catch a flight, everything you need is on the departures side above.
Lounges, dining, and shops live inside each terminal past security — handy once you're through, but they shouldn't change when you leave home. Browsing other airports? TSA wait times by airport lists them all.
