DENVER, CO--NOVEMBER 24TH 2010--Airline passengers going through security on national

Thirteen years after the 9/11 attacks, Americans are beginning to adjust to less oppressive security checks at airports. The Transportation Security Administration (TSA) has moved from a “one-size-fits-all” to a more efficient risk-based approach when it comes to airport security.

Within a year, TSA enrolled more than 740,000 travelers in its Precheck program, which, for an $85 fee, allows travelers who have passed a background check to use quicker screening lanes at more than 120 U.S airports.

According to HomeLand Security News Wire, further to more streamlined airport screening operations, Congress has urged the TSA to develop more partnerships with private companies who can handle airport screenings.

In addition to PreCheck, fast screening service is available for returning international travelers at U.S. airports and borders through Global Entry, Sentri, and Nexus.

“I’m hopeful that we will have some more people being enrolled through the third-party private sector, which could expand perhaps next year significantly the numbers. Instead of hundreds of thousands it may literally be in the millions — which we would then need to accommodate by increasing even more the number of T.S.A. PreCheck lanes,” said TSA Administrator John S. Pistole.

Third-party partnerships may allow the TSA to expand its fast screening service to more airports while the agency deals with budget cuts.
