U.S. Attorney Karen Loeffler's office on Friday announced the plea entered by Nobuya Michael Ochinero.
KTUU-TV reports (http://is.gd/JNt1Z5) that charging documents say the man was on several medications on Feb. 10 when he boarded the flight.
Court papers say Ochinero said he drank four shots of gin and two beers on board. Passengers and flight attendants say he pushed and berated them after he was refused further alcohol. He was eventually strapped to his chair until the plane landed in Anchorage. His blood alcohol content was measured at 0.137.
Prosecutors say Ochinero has agreed to reimburse the airline for its costs.
Sentencing is set for July 7.
