DALLAS -- Federal authorities say 10 people who worked at Dallas-Fort Worth International Airport used commercial flights to distribute methamphetamine.

• 10 workers used commercial flights to send drugs across the country
• Workers are accused of using their positions to bypass security
• Drugs were flown to Charlotte Douglas International Airport

Prosecutors announced Tuesday that the 10 were arrested a day earlier and each indicted on a count of conspiracy to possess with intent to distribute a controlled substance. They believed they were transporting meth and didn't know they were working with undercover agents. 

Authorities say beginning in 2016 the group used their positions to bypass security and place the meth on flights. They allegedly had 145 lbs. (66 kilograms) of counterfeit drugs transported to various domestic destinations including Arizona, New Jersey and North Carolina.

"Like many cases that my office prosecutes, this is about greed and people who abuse their positions of trust. This case shows the lengths that these individuals would go to. Individuals who are trusted with insider knowledge of our commercial airport system that they will go to just obtain cash,” U.S. Attorney Erin Nealy Cox said. “It shows that these criminal defendants were more than willing to use their trusted positions at the airport to bypass security measures and to exploit security vulnerabilities.”

At least one defendant had said he would transport firearms on commercial flights. The employees were arrested Monday.

The defendants worked for Envoy Air, which is a regional carrier owned by American Airlines, and for Spirit Airlines.
