An American Airlines plane travelling from Miami to London has had to turn back because a passenger refused to wear a face mask, the airline has said, reports BBC.
American Airlines said flight AAL38 with 129 passengers on board returned to Miami where police were waiting.
She has been placed on a list of people barred from flying with American Airlines, pending further investigation, the airline said.
The Wednesday flight turned around about an hour into its journey, according to tracking service FlightAware.
The woman was sitting in first class, another passenger Steve Freeman told Miami's Local 10 news. "There was a lot of drinking involved and I was nervous. She sat behind us in first class," he said.
"I could see the writing on the wall - they gave her a lot of warnings, so we were kind of ready for it."
Passengers on the flight to London's Heathrow Airport were re-booked on to another flight for Thursday.
Another passenger said she was disappointed.
"They wouldn't really say anything, and I don't believe they told the flight attendants anything either, because they said that all they could say was there was an extreme incident with a passenger and they had to turn around," she told the station.
Airlines reported nearly 6,000 incidents involving unruly passengers last year and 151 in the first two weeks of this year, according to the Federal Aviation Administration. Most of them involved passengers who refused to wear masks.
