Are you seeing viral 'hacks' for skipping long TSA airport security lines? Here's what works-and what doesn't

"According to the Transportation Security Administration, many airports could "literally shut down . . . particularly smaller ones," if TSA officers continue to call out instead of coming to work. While TSA can't technically close an airport, the catch is, planes can't take off without passengers and crews going through security."

"TSA PreCheck Touchless ID, which is available in select airports for participating airlines, uses facial recognition technology to verify your identity for faster processing. Its own dedicated lane often moves faster than regular TSA Precheck. Instead of showing your ID at security, TSA will scan your face."

Airport security lines have extended significantly across the country due to Department of Homeland Security funding disputes causing TSA officers to work without pay and call out from their shifts. Austin-Bergstrom International Airport experienced particularly long delays with passengers waiting in lines during early morning hours. The Transportation Security Administration warns that smaller airports could face operational shutdowns if staffing shortages continue, since planes cannot depart without security screening. TSA PreCheck Touchless ID, available at select airports with participating airlines, uses facial recognition technology to verify passenger identity and offers dedicated lanes that move faster than standard TSA PreCheck. Passengers must enroll in this program before checking in for their flights.
