(CNN)A woman who punched a flight attendant on a May Southwest Airlines flight from Sacramento to San Diego pleaded guilty to interfering with a flight attendant, according to the U.S. Department of Justice.
A flight attendant asked Vyvianna Quinonez, 28, to buckle her seatbelt, stow her tray table, and wear her mask properly, as the May 23, 2021 flight was on its final descent, according to a plea agreement reached last month. After requesting that Quinonez comply, she returned to her own seat for landing.

The flight attendant was left with three chipped teeth, she needed stitches on her face, and according to the plea agreement, she also “had a bruise in the shape of fingers on her right forearm.” The flight attendant who was assaulted was simply doing her job to ensure the safety of all passengers aboard the plane,” said Acting United States Attorney Randy Grossman. “It’s inexcusable for anyone to use violence on an airplane for any reason, particularly toward a flight attendant who is there to keep all the passengers safe. We are not going to tolerate violence or interference with the flight crew, and we will pursue criminal charges against those who break the law.” Quinonez’s lawyer declined to comment when contacted by CNN. The day after the incident, the union representing Southwest flight attendants said passenger misconduct has reached an “intolerable level.” The in-flight incidents and other working conditions, the union said, left its ranks “weary, exhausted, frustrated and forgotten.” Unruly airline passengers could lose TSA PreCheck credentials. 'If you act out of line, you will wait in line' This incident was one of 5,779 incidents reported to the Federal Aviation Administration so far this year regarding disruptive and sometimes violent passengers onboard aircraft. More than 4,000 of the incidents were related to mask-wearing. Quinonez will be sentenced on March 11, 2022. She could face up to 20 years in prison and a $250,000 fine.
