Fort Worth-based American Airlines has launched a new system to catch passengers who try to sneak ahead in line.

According to a release, the airline is deploying a program in which technology is used to deter passengers who try to board before their official boarding group has been called.

Passengers who try to board early will not only hear a beep when they scan their boarding pass, but a tattletale message will pop up on the scanner, alerting the American Airlines employee of the passenger's correct group.

The airline trialed this modern technology over the past month at Albuquerque International Sunport, Ronald Reagan Washington National Airport, and Tucson International Airport. It will now be deployed at more than 100 airports across the U.S.

If a customer boards before their assigned group is called, the new software will not accept the boarding pass and instead makes an audible sound to alert the gate agent and customer that the group has not yet been called. In these instances, the American team member will invite the customer to rejoin the line when their boarding group is called.

According to a story in the NY Post, airline employees have a name for these people: “gate lice."

A statement from American Airlines says that those passengers who are paying for early access should get their just desserts. People who are paying extra are mad when others get the same benefits.

"The new technology is designed to ensure customers receive the benefits of priority boarding with ease," it says.

Surely a factor is the way American Airlines' current boarding system has become an exercise in the haves vs. the have-nots, with nine levels of boarding groups, from elite status members and credit card holders all the way down to the Basic Economy nobodies. It's gotten worse since the pandemic, with extra charges applied to every element of flying, including a charge if you want to choose your own seat.

As an explanation of why people might do it, the NY Post cites a theory that travelers try to get ahead "out of a tendency of conformity and a sense of competition."

Public shaming is a powerful motivator, and Larry David fans would surely agree that line-cutters should always be called out — but in this case, there is an actual valid reason for trying to get a jump in line, and that can be summed up in two words: overhead bins.

Too many travelers place their luggage in overhead bins that are not located over their seats. Who has not seen the guy breezily stash his suitcase in whatever bin is closest? And this is an inequity that is not addressed by flight attendants, who admittedly have enough on their hands.

But the fact remains that if you get on the plane when your boarding group boards, the odds are slimmer that your designated overhead bin is going to have room for your suitcase.

If the airline is not going to enforce the overhead bin situation, then it's hardly fair to blame gate lice for worrying about where their suitcase is going to end up — or worse, whether they'll face the horror of having to get their bag checked at the last minute because some other passenger stole their overhead space.
