Long security lines are not inevitable. Several trusted traveler programs let you bypass the standard screening queue at STL. Here is what is available and what each program costs.
Available at STL and 200+ US airports
TSA PreCheck members use a dedicated screening lane where you can keep your shoes, belt, and light jacket on. Laptops and 3-1-1 compliant liquids stay in your bag. The average PreCheck wait time is under 5 minutes nationwide.
CLEAR is not currently available at St. Louis Lambert International Airport
CLEAR uses biometric screening (fingerprints or iris scan) to verify your identity, letting you skip the ID verification line entirely. When paired with TSA PreCheck, you go from the CLEAR lane directly into the PreCheck screening line — often clearing security in under 2 minutes.
Several travel credit cards reimburse the enrollment fees for trusted traveler programs. These cards pay for themselves by covering your PreCheck, Global Entry, or CLEAR membership costs as a statement credit.

Best for international travelers
Global Entry includes TSA PreCheck and adds expedited US customs processing when you return from international trips. Instead of waiting in the standard customs line, you use a kiosk with facial recognition and walk through in minutes. If you fly internationally even once a year, Global Entry is the better value over standalone PreCheck.
Best for US-Canada travelers
NEXUS is a joint US-Canada trusted traveler program that includes both TSA PreCheck and Global Entry benefits at the same price as Global Entry alone. If you travel between the US and Canada, NEXUS is the best overall value — you get expedited screening in both countries plus all the domestic PreCheck benefits.
