American Airlines expands 'gate lice' crackdown to more than 100 airports

The system audibly flags when a passenger attempts to board the plane before their designated assignment is called and will automatically reject the ticket.

It will now expand to more than 100 airports ahead of the holiday season.

Julie Rath, American's senior vice president of airport operations, reservations and service recovery, said in a press release the ability for customers to board with their assigned group is important to them.

Travelers boarding with a companion who has an earlier boarding group may still do so. The agent will override the alert accepting the boarding pass, according to the press release.

The technology "provides team members with more insight into the number of customers in each boarding group" and "displays anticipated arrival time for incoming flight connections," according to American's site.

In October, a representative from American told Fox News Digital via email, "The new technology is designed to ensure customers receive the benefits of priority boarding with ease."

The representative added that it "helps improve the boarding experience by providing greater visibility into boarding progress for our team."

Fox News Digital reached out to American Airlines for additional comment.
