As the 49th State, U.S. residents don’t need a passport to go to Alaska, but as of October 1, 2020, you will need a REAL ID.
Beginning October 1, 2020, U.S. citizens ages 18 and up traveling by air within the United States will need REAL-ID compliant identification to go through airport security checkpoints. REAL ID compliant identification includes a state-issued REAL ID, U.S. Passport, military ID, or other form of compliant ID. REAL ID driver’s licenses – generally marked with a star on the upper portion of the card – are available at your state’s Department of Motor Vehicles. Remember, if you’re traveling anywhere in the United States – including Alaska – after October 1, 2020, you’ll need REAL ID-compliant identification to go through TSA checkpoints.
