A British man whose drunken antics forced a Jan. 4 WestJet plane from Calgary to London to have to turn around now has to pay $21,260.68 to the airline to account for fuel costs.

David Steven Young, 44, pleaded guilty to resisting arrest and not adhering to safety instructions.

"Mr. Young was sentenced to one additional day of jail on each count, considering the seven days he spent in pretrial custody..." prosecutor Lori Ibus told USA TODAY. "He was also ordered to pay WestJet $21,260.68 in restitution as part of his sentence. This amount represents the cost to WestJet for the fuel costs relating to the having to return to Calgary International Airport."

It was revealed in court that Young, who has battled alcoholism, drank approximately six alcoholic beverages prior to boarding the London-bound WestJet flight, according to the Independent and CBC News.

Young repeatedly tried making his way to the bathroom, even when it wasn't safe to move around, "right after take-off," a court document obtained by USA TODAY reveals.

"Initially, the accused begrudgingly returned to his seat but again got up shortly afterwards and again tried to push his way into the locked lavatories," according to the document. He became aggressive with both flight attendants and another passenger, the court document states. Because flight attendants and the passenger "were left shaken and threatened by the accused's behavior (being verbally aggressive, swearing, shouting, fists clenched) enough," the flight crew chose to divert the flight.

To land safely, the captain needed to dump about "20,000 pounds of fuel," per the court document.

Young apologized in written statement, saying he was sorry for "damage and inconvenience" he caused his fellow passengers. WestJet's losses in both fuel and passenger payments could reach more than $200,000, though the judge in the case Brian Stevenson, said WestJet could seek this payment from Young through a civil case.
