Beginning Saturday, June 21, passengers that willfully refuse to provide identification at security checkpoint will be denied access to the secure area of airports. This change will apply exclusively to individuals that simply refuse to provide any identification or assist transportation security officers in ascertaining their identity. This new procedure will not affect passengers that may have misplaced, lost or otherwise do not have ID but are cooperative with officers. Those passengers without ID may be subjected to additional screening protocols, including enhanced physical screening, enhanced carry-on and/or checked baggage screening, interviews with behavior detection or law enforcement officers and other measures. This initiative is the latest in a series designed to facilitate travel for legitimate passengers while enhancing security. Positively identifying passengers is an important tool in TSA’s multi-layered approach to airport security.
