Reminder: Starting February 1, if you don’t have a REAL ID or acceptable form of ID (like a passport!) for domestic flights, you may pay a $45 fee to verify your identity through TSA ConfirmID. A passport card ($30) or passport book are both accepted REAL ID alternatives for domestic air travel and can help you avoid this fee, but just remember that a passport card cannot be used for international air travel (you'll need a passport book for that). Learn more about the Real ID policy at TSA.gov/real-id and about passport cards at travel.state.gov/passportcard.
