Story highlights A former Korean Air executive is found guilty of violating aviation law after interrupting a flight over nuts

She has been sentenced to one year in jail for all charges

Seoul, South Korea (CNN) It started with a first-class aviation executive throwing a fit on a flight over her nuts.

It ended Thursday with that former executive sentenced to jail for one year.

Heather Cho was working for Korean Air on December 5 when, as a first-class passenger on an international flight, an attendant served her macadamia nuts in a bag. Cho wanted them on a plate and demanded that the plane go back to the gate at New York's JFK airport so a crew member could be kicked off the flight.

A South Korean judge said that her actions threatened the development of the aviation industry and inconvenienced passengers, and ruled that she violated aviation law, changed a flight path and interfered with operations.
