ATLANTA -- The next time you're at Hartsfield-Jackson International Airport and you enter a shop or restaurant notice the sign placed in front of the cash register. Look down slightly. There it is, in English and Spanish.

Its called a Human Trafficking Notice and the question is simple: "Are you or someone you know being sold for sex or made/forced to work for little or no pay, and cannot leave?"

Airport spokesman Reese McCranie said there's a reason the signs are all positioned at about four feet off the ground.

"They're at eye level for a child to actually see the print and the 1-800 number to call and get help if they think they are a victim of trafficking," said McCranie.

The airport is partnering with the Georgia Bureau of Investigation following a recent report that Atlanta has the biggest cash-based underground sex economy in the nation. The Urban Institute's Justice Policy Center reported street and online prostitution, brothels and massage parlors are bringing in $290 million a year.

"We've decided to partner with the GBI and they are responsible for the wording of the message. We wanted to make sure we did everything we could to help stem this tide," said McCranie.

In addition to the signs, airport employees including Larry Newman who works for We Juice It, are getting trained on how to spot possible sex trafficking.

"There are a lot of things to look for, like if a child is hesitant to talk without permission or if they look uncomfortable in the situation. Sometimes you may overlook that someone is actually in danger unless you know what to look for. What I learned in the training is there is more than one way that people might cry out for help," said Newman.
