Anyone who has stood in line at an airport departure gate, waiting patiently for their zone to be called, has probably seen a scenario in which someone tries to rush forward and board the plane before their group has been called.

Now American Airlines is the first airline to test new technology that could help crack down on passengers who try to cut the line.

The technology would give gate agents an audible signal if someone tries to board early, prompting the passenger to step aside and wait until the correct group is called.

“We are in the early stages of testing new technologies that will be used during the boarding process. They are designed to ensure customers receive hassle-free priority boarding and to improve the boarding experience through increased visibility,” an airline representative told ABC News.

The technology is currently being tested at three US airports: Albuquerque International, Tucson International Airport and Ronald Reagan Washington National Airport.

The airline told ABC News that it is pleased with the test results and technology so far.
