The flight made an emergency landing in Minneapolis yesterday after the passenger tried to open a rear-door. The Boeing 737 was on its way from New York's JFK Airport to Seattle, Washington.
"We did receive reports that this passenger attempted to access a door at the rear of the aircraft. The passenger was unsuccessful as it is physically impossible to open an aircraft door while the aircraft is pressurised and in flight," Alaska Airlines spokesperson Halley Knigge was quoted as saying by KIRO-TV.
Minneapolis-St. Paul International Airport Police told the TV station that officers questioned the unruly passenger and determined he presented a danger to himself.
The passenger was taken to a local hospital.
An airport spokeswoman said the suspects name is not being released at this time.
