It's called TSA PreCheck.
Kennedy is one of 28 airports where the Transport Security Administration is expanding expedited screening.
American Airlines launched the program at the airport yesterday.
The change is significant from the rules put in place after the 2001 terrorist attacks as preapproved frequent fliers will be allowed to get through security faster.
PreCheck passengers still go through screening checkpoints but get a separate line and in most cases a streamlined process.
They can keep on their shoes, belts, and light coats at designated checkpoints, according to the TSA. They also can leave their laptops and liquids in their carry-ons when being screened.
Participants in the TSA's PreCheck program must be invited by their airline, but they can also apply through the Customs and Border Protection.
