As of October 1, 2020, in order to use your driver’s license to board a commercial aircraft, your license will need to be REAL ID compliant. For many states, if you see a gold or white-on-black star in the upper right corner of your license, you’re already there. (California uses a “golden bear” and Washington State isn’t using the star symbol.)
Without a REAL ID compliant driver’s license, you may still board an aircraft using your government-issued passport.
You can learn more about REAL ID on the TSA’s website: https://www.tsa.gov/real-id.
Due to the Coronavirus/Covid-19 pandemic, implementation of REAL ID may be delayed. Your best sources of information are DHS and TSA.
