Extensive passenger data has been sold to the US Government by major airline companies including Delta, United Airlines, and American Airlines, new documents reveal.

US travellers’ domestic flight records, including their names, full itineraries, and financial details were sold to Customs and Border Protection (CBP).

CBP is a part of the Department of Homeland Security (DHS). They said they acquired the data to track people of interest’s air travel.

The documents, obtained by 404 Media, showed that passenger information was sold through a data broker that major airlines including Delta, American Airlines and United Airlines collectively own.
