Starting Wednesday, certain American Airline ticket holders are being steered into a fast lane, allowing them to move more quickly through security checkpoints.
First, those passengers must enroll in the TSA's new "Pre-Check" program, which includes providing personal information and submitting to background checks.
In return, participants will be allowed to wear their shoes, belts and coats while bypassing screening measures.
The program, which is being run by TSA and U.S. Customs and Border Protection, is being tested for eligible passengers flying on American Airlines out of Los Angeles International Airport; or Delta out of Hartsfield-Jackson Atlanta International, Detroit Metropolitan Wayne County and McCarran International airports; or on American Airlines out of Dallas/Fort Worth International, Miami International and McCarran International airports.
So far, only American Airlines and Delta have partnered with the TSA, but United and US Airways are expected to join the program later this year.
As for eligibility, the TSA states that certain frequent flyers from Delta Air Lines, American Airlines and certain members of the U.S. Customs and Border Protection's Trusted Traveler programs, including Global Entry, SENTRI and NEXUS who are U.S. citizens, are qualified to participate in the program.
Meantime, the TSA said it will continue to carry out random security checks.
