TSA PreCheck at SAT
TSA PreCheck lanes at San Antonio International Airport are usually much shorter than the standard line: TSA reports that the large majority of PreCheck travelers wait under 10 minutes, and you keep shoes, belts, light jackets and laptops in place. Lanes can open later and close earlier than the main checkpoint, so if you fly very early or late, plan for the standard wait above. Check the official SAT website for which checkpoints have PreCheck and CLEAR lanes.
CLEAR and Global Entry
CLEAR speeds up the ID check and walks you to the front of the screening line where it operates; you still go through screening. Global Entry includes PreCheck for eligible members and speeds up re-entry from international trips.
