The airlines enroll a lot of the Pre-Check fliers, but the TSA is expanding the program. Travelers can now enroll at new centers in Glendale, Signal Hill and Carson.
TSA's Pre-Check program allows pre-screened passengers to go through a separate, shorter line at security.
TSA spokesperson Nico Melendez says passengers will not be required to take off their belts, shoes or jackets and will be allowed to keep their laptop in their bag.
It also separates experienced travelers from those that don't fly that often, which could save a lot of time.
"I think it's the long line first, having the opportunity to get into a shorter line and move more quickly with people who are there and ready to understand that your situation is one that could be moved through," said Pre-Check flyer Richard Cicetti.
The expedited screening program costs travelers a one-time fee of $85.
