The former Korean Air executive sentenced to one year in prison for forcing a plane back to the gate over a bag of nuts has appealed the ruling.

Yoon & Yang LLC, a Seoul law firm representing Cho Hyun-ah, said Friday that she has filed a notice of appeal to a Seoul court.

It comes a day after she was found guilty of violating aviation safety law and other charges. Cho will ask the court to reconsider her sentence.

The daughter of Korean Air's chairman achieved worldwide notoriety for her onboard tantrum over being served macadamia nuts in a bag instead of on a dish.

The prison sentence was a departure from previous rulings that have shown leniency to South Korea's tycoons.
