The FBI maintains the federal no-fly list as a subset of the Terrorist Screening Database, which includes people who are either “known terrorists” or are reasonably suspected of being involved in terrorism. But the penalties climbed: The FAA proposed more than $8.4 million in fines against unruly passengers last year. U.S. Attorney General Merrick Garland told prosecutors to prioritize investigations involving disruptive air passengers in 2021. They could also be placed on a no-fly list if they have been fined for interfering with procedures or security systems on a plane, or causing someone to do so.
