Secure Flight

result in the transfer of responsibility for passenger watch list matching to TSA for flights into, out of, and over the United States.

The Intelligence Reform and Terrorism Prevention Act (IRTPA) of 2004 requires the Department of Homeland Security (DHS) to assume from aircraft operators the function of conducting pre-flight comparisons of airline passenger information to federal government watch lists for international and domestic flights.

TSA has stated it will not collect or use "commercial data"[clarification needed] to conduct Secure Flight watch list matching.

[4] Secure Flight has many similarities with CAPPS II and the No Fly List, and therefore raises the same validated[5] concerns about civil liberties and due process.

Specifically, civil libertarians argue that under the Secure Flight program, there are insufficient redress mechanisms for innocent citizens on watch lists.
