Airport travelers without a Real ID will now have added costs at security checkpoints, as new enforcement measures took effect Sunday.

While Real ID has been required for domestic air travel since May 2025, passengers who arrive at TSA checkpoints without one will now be subject to a $45 fee beginning Feb. 1.

The $45 payment allows travelers to proceed through security for a 10 day period. Those taking trips longer than 10 days could be required to pay the fee again, bringing the total to $90. TSA officials also warn those without Real ID may face longer screening times.

The Real ID Act was passed by Congress in 2005 following the Sept. 11 attacks, but full implementation was delayed for years. The Transportation Security Administration says the ID adds an extra layer of security for domestic travel.

Travelers without a Real ID can still use a valid U.S. passport in place of the enhanced driver’s license.
