CALGARY — For one WestJet passenger, a few drinks have not only led to a bad hangover but also a hefty fine of over $20,000.

David Stephen Young, who flew from Calgary to London on Jan. 4, was slapped with the fine after pleading guilty to Criminal Code and Aeronautics Act charges.

While onboard, Young was refused access to the aircraft washroom while the seatbelt light was activated. He forced his way into the washroom and, after returning to his seat, became aggressive towards other passengers and the cabin crew.

As a result, the aircraft was forced to return to the Calgary International Airport where Young was arrested and charged with offences, including causing a disturbance, criminal harassment and assaulting a peace officer.

He was ordered to pay a total of $21,260.68 to cover the cost of the fuel that WestJet had to dump before landing. Young was also sentenced to one day in prison for each of his offences.

His attorney says his client is a recovering alcoholic who had several drinks before boarding the aircraft.
