Several major U.S. airlines, including American, Delta, JetBlue, Southwest, and United, have quietly provided the Department of Homeland Security (DHS) with extensive passenger data.
This data includes travel itineraries and payment information, supporting a little-known surveillance program, as detailed in recent court documents.
According to a report from WIRED, these revelations emerged from a federal lawsuit filed by the watchdog group The Brennan Center for Justice. The lawsuit accuses the DHS of expanding a program called the Quiet Skies initiative without proper public disclosure or legal authority. This program, managed by U.S. Customs and Border Protection (CBP), monitors travelers classified as “unknown threats,” which includes U.S. citizens.
Court filings indicate that the data shared included detailed travel histories, ticket purchases, seating assignments, and baggage details—information that the Transportation Security Administration (TSA) does not typically receive. According to the filings, airlines provided this data voluntarily and without informing passengers.
Privacy advocates have raised serious concerns about transparency, oversight, and consent, arguing that the Quiet Skies program has been in operation for years with minimal public scrutiny and little evidence of its effectiveness.
While the DHS defends the program as a means to identify suspicious travel patterns and enhance national security, critics argue that it lacks accountability and functions in a legal gray area.
Most of the airlines mentioned in the lawsuit have declined to comment, and the DHS has not confirmed the duration of this data-sharing practice or the number of affected passengers.
This case underscores the ongoing tensions between national security measures and individual privacy rights, especially in light of expanded government surveillance programs following the terrorist attacks on September 11th, 2001.
