The TSA is planning big changes to airport security. Here's what they mean for travelers.

It will scrap the contentious TSA Gold+ initiative, but still wants more private security contractors.

Horizon 25 also seeks to enhance TSA PreCheck and help acquire new technologies.

Airport security could soon look very different.

The Transportation Security Administration announced a new strategy on Monday, called Horizon 25, ahead of the agency's 25th anniversary.

It said it would scrap TSA Gold+, a Trump Administration initiative designed to expand the use of private contractors to handle airport security.

Trump has said he believes privatizing aviation systems while maintaining government oversight would save money, improve efficiency, and enhance safety.

However, the program has faced fierce opposition from the union for TSA workers.

Last month, the American Federation of Government Employees said privatization "ignores lessons" from airline tragedies.

"The administration's actions should concern all Americans, and AFGE will continue to speak out against any proposal that threatens our members' jobs and jeopardizes the safety of the flying public," said Everett Kelley, the union's national president.

While TSA Gold+ has now been discarded, the agency isn't giving up its goals of further privatization.

The TSA said it plans to "accelerate public-private partnerships" with "an evolved Screening Partnership Program." The SPP lets airports use private security contractors for passenger and baggage screening.

20 airports have signed up to it, the largest being San Francisco International Airport.
