Your State Driver's licenses may not be accepted for Domestic US Air Travel in January. The Department of Homeland Security is slowly raising the security requirements of our regular drivers licenses in the United States as part of their Real ID program. Some states have recently received an extension, but others have not and their grace period expires January 22, 2018. If you have a driver's license from those states, you will need a passport or other enhanced ID to fly even on a US Domestic only flight.
