Summary

The TSA must make rules so airlines, airports, ticket agents, and their employees promptly tell the TSA when they get information about a threat to civil aviation (unless the notice came from the U.S. government). If the TSA decides a specific threat cannot be handled so passengers and crew are safe, the TSA must cancel that flight or series of flights. The President must make rules about when to warn the public and who decides that, how to give timely notice (including a toll-free number), and who can cancel flights. The rules must consider things like how specific and credible the threat is, whether it can be stopped, protecting intelligence sources, canceling flights instead of public warning, and whether people can reduce their risk after a warning. The TSA must also make rules to notify flight and cabin crews, may warn only certain travelers if the threat applies only to them, limit who can see threat information without blocking security duties, and share these rules with DOT, State, Justice, and air carriers.

(a)Under guidelines the Administrator of the Transportation Security Administration prescribes, an air carrier, airport operator, ticket agent, or individual employed by an air carrier, airport operator, or ticket agent, receiving information (except a communication directed by the United States Government) about a threat to civil aviation shall provide the information promptly to the Administrator.
(b)If a decision is made that a particular threat cannot be addressed in a way adequate to ensure, to the extent feasible, the safety of passengers and crew of a particular flight or series of flights, the Administrator of the Transportation Security Administration shall cancel the flight or series of flights.
(c)(1)The President shall develop guidelines for ensuring that public notice is provided in appropriate cases about threats to civil aviation. The guidelines shall identify officials responsible for—
(A)deciding, on a case-by-case basis, if public notice of a threat is in the best interest of the United States and the traveling public;
(B)ensuring that public notice is provided in a timely and effective way, including the use of a toll-free telephone number; and
(C)canceling the departure of a flight or series of flights under subsection (b) of this section.
(2)The guidelines shall provide for consideration of—
(A)the specificity of the threat;
(B)the credibility of intelligence information related to the threat;
(C)the ability to counter the threat effectively;
(D)the protection of intelligence information sources and methods;
(E)cancellation, by an air carrier or the Administrator of the Transportation Security Administration, of a flight or series of flights instead of public notice;
(F)the ability of passengers and crew to take steps to reduce the risk to their safety after receiving public notice of a threat; and
(G)other factors the Administrator of the Transportation Security Administration considers appropriate.
(d)The Administrator of the Transportation Security Administration shall develop guidelines for ensuring that notice in appropriate cases of threats to the security of an air carrier flight is provided to the flight crew and cabin crew of that flight.
(e)Notice of a threat to civil aviation may be provided to selective potential travelers only if the threat applies only to those travelers.
(f)In cooperation with the departments, agencies, and instrumentalities of the Government that collect, receive, and analyze intelligence information related to aviation security, the Administrator of the Transportation Security Administration shall develop procedures to minimize the number of individuals who have access to information about threats. However, a restriction on access to that information may be imposed only if the restriction does not diminish the ability of the Government to carry out its duties and powers related to aviation security effectively, including providing notice to the public and flight and cabin crews under this section.
(g)The guidelines developed under this section shall be distributed for use by appropriate officials of the Department of Transportation, the Department of State, the Department of Justice, and air carriers.
