The Transportation Security Administration rolled out PreCheck, the expedited security program for pre-screened fliers, this week at Los Angeles International Airport, the sixth airport in the nation to participate in the pilot program since it started last year.
Here's how it works: Fliers who are U.S. citizens provide personal information and undergo background checks to qualify for traveler programs approved by U.S. Customs and Border Protection, such as Global Entry, SENTRI and NEXUS. Once fliers are deemed eligible, they are allowed to keep their shoes and belts on and leave laptops and 3-1-1 liquids inside their carry-on bags.
Passengers receive boarding passes embedded with a bar code that signals to the TSA they are eligible for PreCheck. They may then be screened at a fast lane where they forgo the shoes-and-belt routine. But this doesn't mean PreCheck passengers get a pass. Their bags are still scanned for security, and they're still subject to random security checks like everyone else, according to the TSA.
