The rate of unruly passenger incidents on airplanes fell to the lowest level since 2020 a week after a federal judge ended a government mask mandate for public transportation, the Federal Aviation Administration said Wednesday.

The FAA said there were 1.9 reported incidents per 10,000 flights during the week ending April 24, compared to 4.4 reported incidents per 10,000 flights the prior week. The FAA said previously about 70% of reported incidents involved the enforcement of masking rules.
