Airlines reported nearly 6,000 incidents involving unruly passengers last year and 151 in the first two weeks of this year. Most incidents involved passengers refusing to wear masks. The latest incident, on 20 January, involved an American Airlines passenger who refused to wear a mask on a flight to Heathrow from Miami, which forced the Boeing 777 carrying 129 passengers to return to Florida. The American Airlines statement said the diversion was ‘due to a disruptive customer refusing to comply with the federal mask requirement’. See also
