Cases of unruly airline passenger behavior have dropped by 80% since they peaked in 2021, the Federal Aviation Administration said.

As of Monday, the FAA has recorded 1,117 instances of unruly behavior in 2023, down from 5,973 cases in 2021.

"There is nothing especially mysterious about this," said Kathleen Andereck, the director of the Center for Sustainable Tourism at Arizona State University. "No more COVID protocols to deal with such as mask wearing, and less stress. That is what most of the drop is related to."

Twenty-two cases of particularly unruly conduct were recently referred to the FBI, the FAA said Tuesday. The violations took place from Dec. 2021 to April 2023 and include physical assault, yelling and cursing, vaping, refusing to remain seated, sexual misconduct toward flight attendants and sexually assaulting other passengers, including minors.
