TSA's new policy gets service members through security quicker Published Dec. 10, 2013 By Staff Sgt. Angela Wilson 20th Logistics Readiness Squadron SHAW AIR FORCE BASE, S.C. -- On Dec. 20, 2013, the process for participating in Transportation Security Administration's PreCheck program will change. PreCheck is a voluntary, expedited security screening process that allows participants to keep on their shoes, belt, and light jacket, and leave laptops and 3-1-1 compliant liquids in their carry-on bags. Under the new process, service members including reservists, National Guardsmen, and members of the Coast Guard, will use their Department of Defense identification number as their "known traveler number" when making official travel or leisure airline reservations in order to use the dedicated TSA PreCheck security lanes at any of 100 airports that offer the program. Members do not have to be in uniform or on official travel to participate in the program. To participate, service members must enter their DoD ID number, found on the back of their Common Access Card, as the known traveler number when making reservations through Defense Travel System, through a commercial travel office, or when booking leisure travel through the airline or travel websites. Until Dec. 20, service members can still participate by presenting their CAC to be scanned and verified at dedicated PreCheck security lanes. This program is available to service members at these airports only: Baltimore-Washington International (BWI) Charlotte Douglass International (CLT) Denver International (DEN) Hartsfield-Jackson Atlanta International (ATL) Honolulu International (HLN) Ronald Reagan Washington National (DCA) Seattle-Tacoma International (SEA) St. Louis International (STL) Ted Stevens Anchorage (ANC) Washington Dulles International (IAD) TSA will phase out the CAC scan process by March 31, 2014.
