Completing TSA passenger screening


TSA serves the traveling public, which is comprised of experienced business travelers, Trusted Travelers (i.e., Global Entry, TSA PreCheck® passengers), families, passengers with medical conditions or disabilities, individuals with limited English proficiency, airport and airline employees, and beyond. All passengers or individuals seeking access to the secured area of the airport must undergo TSA security screening at more than 440 airports across the country. The screening process involves the use of various technologies, such as Advanced Imaging Technology, Walk-Through Metal Detectors, Explosive Trace Detection, Digital Identification and Mobile Driver’s Licenses, and X-ray machines, to detect threats and prohibited items. On average, over 2 million passengers are screened daily, adding up to more than 750 million passengers annually.

Travelers can contact TSA to inquire about permitted or prohibited items, get information on REAL ID, seek assistance through the screening checkpoint via TSA Cares, report security threats or suspicious activity, submit a complaint or compliment, file a claim, or learn more about TSA PreCheck®.
