Reportedly, the woman rushed down the corridor and made her way to the plane's emergency door which she tried to pry it open while repeating chanting 'I am God!'.
Video shared on social media showed passengers attempting to subdue the woman by pinning her to the floor. Authorities said the woman, who hasn't been arrested or identified, was being examined by the Idaho Department of Health and Welfare.
"She wasn't acting right, or normal, from the very beginning [of the flight]", said Scott T. Smith, a California man told the Idaho Statesmen.
The aircraft landed safely and the woman was taken in by waiting police for medical evaluation.
According to other passengers, the woman appeared nervous at first, but in no time, she started acting odd.
All other passengers were able to safely deplane at the Boise Airport, and no one was hurt, the airline said.
Cops will then decide whether or not to hand a file over to prosecutors indicating whether she should be charged with any crime.
'I read it as one of them is trying to get over the fear of flying. "I could tell that one or both were uneasy with flying".
SkyWest officials say the passenger was restrained on the flight, and police met the aircraft at the gate. "The unruly customer was held for questioning by law enforcement".
Smith said people remained calm during the incident.
