If you're a customer of Delta Air Lines, American Airlines or United Airlines, it's likely that data about your domestic flights—including your name, itinerary and payment details—has been sold to U.S. Customs and Border Protection (CBP), according to documents obtained by the independent outlet 404 Media.
CBP says it uses this data to help state and local law enforcement track the air travel of people of interest. But civil liberties advocates and lawmakers say the Department of Homeland Security's (DHS) approach is deeply concerning, warning that it may bypass standard legal processes.
