To comply with the 2005 Real ID Act, which the U.S. government has been slowly implementing for the past decade, citizens in a number of different U.S. states will now be forced to obtain a passport if they want to board an airplane – even for domestic flights.
The Department of Homeland Security have declined to comment on why certain states have been singled out, but starting in 2016, residents of New York, Wisconsin, Louisiana, Minnesota, New Hampshire, and American Samoa will need a passport to fly domestically. All other states will still be able to use their state-issued driver’s licenses and IDs – for now, at least.
According to the Department of Homeland Security’s guidelines on enforcement of the Real ID Act,
“The Department of Homeland Security (DHS) announced on December 20, 2013 a phased enforcement plan for the REAL ID Act (the Act), as passed by Congress, that will implement the Act in a measured, fair, and responsible way.
