In just over three months, residents from nine states will be required to show a U.S. passport to board any flight, including domestic travel, according to new TSA guidelines.
"Starting January 22, 2018, you will need a driver's license or ID from a state compliant with the REAL ID Act, a state that has an extension for compliance, or an alternate ID to fly," the Department of Homeland Security wrote in a public flier.
People who possess an ID from Kentucky, Maine, Minnesota, Missouri, Montana, Oklahoma, Pennsylvania, South Carolina and Washington will need to use a passport to travel domestically if the states do not upgrade their security standards.
Passed by Congress in 2005, the REAL ID Act establishes the minimum security standards for state-issued driver's licenses and ID cards. It prohibits federal agencies, like the TSA, from accepting such cards for certain official purposes, including boarding federally regulated commercial aircraft.
