Authorities said a flight attendant broke at least one wine bottle over the head of a passenger who lunged for an exit door during a struggle on a Delta Air Lines flight from Seattle to Beijing on Thursday night.
The disclosure came as 23-year-old Joseph Daniel Hudek IV of Tampa, Florida, appeared Friday in a federal courtroom in Seattle.
He is charged with interfering with a flight crew and could face up to 20 years in prison if convicted.
A criminal complaint says Hudek was served one beer prior to takeoff and did not appear intoxicated.
It says Hudek came out of a bathroom about an hour into the flight and lunged for an exit door in the first-class section.
Two flight attendants tried to stop him and authorities say one broke a wine bottle on him during the struggle.
