(CNN) – Travelers who still don’t have a REAL ID and want to fly could soon have to pay a fee to pass through airport checkpoints.

On Thursday, the Transportation Security Administration proposed an $18 fee for travelers without a REAL ID.

The new rule calls for travelers who don’t have one to be able to pay that fee and use a new biometric kiosk that would allow flyers access to TSA checkpoints for 10 days.

The agency says the fee will cover costs associated with the new technology that’s needed to verify a passenger’s identity.

The fee is also nonrefundable.

There’s no word on when the proposed rule could take effect. An estimated 82 million Americans are expected to travel for Thanksgiving. (CNN, WBBM, WCBS)
