Title 49 › SUBTITLE VII — AVIATION PROGRAMS › PART A — AIR COMMERCE AND SAFETY › subpart iii — safety › CHAPTER 449 — SECURITY › SUBCHAPTER I — REQUIREMENTS › § 44905
Airlines, airports, ticket agents, and their employees must quickly tell the TSA Administrator when they get information about a threat to civil aviation, unless the message came from the U.S. government. If a threat cannot be handled so passengers and crew can be kept safe, the TSA Administrator must cancel the affected flight or flights. The President must write rules about when and how to warn the public. Those rules will name who decides if a public warning is needed, who makes sure the warning is given quickly and clearly (for example by a toll‑free phone line), and who can cancel flights. The rules will weigh things like how specific and credible the threat is, whether it can be stopped, protecting intelligence sources, and whether warning people or canceling flights is better. The TSA must also write rules for telling flight and cabin crews when appropriate. Warnings can be sent only to certain travelers if the threat applies only to them. The TSA will work with other agencies to limit who can see threat information, but not so much that it stops the government from doing its security jobs, including warning crews and the public. The rules must be shared with the Departments of Transportation, State, and Justice, and with airlines.
