Twenty-three-year-old Justin Cox-Sever, of Tempe, Arizona, is accused of calling in fake bomb threats on a flight from Charlottesville, Virginia, to Chicago, and on a flight from Minneapolis to Dickinson, North Dakota.
Both flights made emergency landings. No one was hurt. The plea agreement calls for Cox-Sever to plead guilty to four of the five charges against him related to interfering with an aircraft.
Prosecutors will drop a fifth count, reducing the potential maximum prison sentence from 70 years to 50 years.
