Starting January 22, 2018, driver’s licenses or state IDs issued by several states may not be used to board domestic flights as these IDs do not meet the requirements of the federal REAL ID Act. As a result, residents of Kentucky, Maine, Minnesota, Missouri, Montana, Oklahoma, Pennsylvania, South Carolina, and Washington state will need to use their passports as identification when traveling. Due to a recent surge in passport applications, individuals from these 9 states who are nearing the end of their passport’s validity should apply early for renewal, well in advance of their anticipated travel.
