“The continued growth and passenger participation in TSA Pre✓® affirms our commitment to the evolution of our intelligence-driven, risk-based approach to aviation security,” said TSA Acting Administrator Melvin Carraway. “This milestone is a testament to the outstanding collaborative work between TSA, airports, airlines and most importantly, the traveling public. With more than 330 application centers nationwide, it is easier than ever to apply for expedited screening.”

TSA Pre✓®, an expedited screening program that began in October 2011, enables low-risk travelers to enjoy a smart and efficient screening experience at 133 U.S. airports. TSA Pre✓® travelers may leave on their shoes, light outerwear and belt, keep their laptop in its case and their 3-1-1 compliant liquids/gels bag in a carry-on in select screening lanes.

The TSA Pre✓® application program, which launched in December 2013, allows U.S. citizens and lawful permanent residents to directly apply for TSA Pre✓®. Once approved, travelers will receive a “Known Traveler Number” and will have the opportunity to utilize TSA Pre✓® lanes at select security checkpoints when flying on 11 participating carriers: Air Canada, Alaska Airlines, American Airlines, Delta Air Lines, Hawaiian Airlines, JetBlue Airways, Southwest Airlines, Sun Country Airlines, United Airlines, US Airways and Virgin America.

In partnership with TSA, travelers may also enroll in one of three trusted traveler programs offered by U.S. Customs and Border Protection (CBP): Global Entry, NEXUS or SENTRI. Members of these programs are eligible to participate in TSA Pre✓® and do not need to apply separately; once successfully enrolled in a CBP trusted traveler program, participants must utilize their “PASSID” as their Known Traveler Number.

Last week, CBP announced it enrolled its 2 millionth traveler in Global Entry. Combined, the TSA Pre✓® application program, Global Entry, NEXUS and SENTRI have more than 4.6 million trusted travelers. Together, these four programs provide an improved passenger experience, while enhancing security and increasing system-wide efficiencies for the U.S. Department of Homeland Security.

As always, TSA continues to incorporate random and unpredictable security measures both seen and unseen throughout the airport. All travelers will be screened, and no individual will be guaranteed expedited screening.
