An Incheon-bound flight from New York was delayed after a Korean Air executive demanded the removal of a crew member for failing to serve nuts properly, according to the Korea Times.

Heather Cho, a vice-president of Korean Air and daughter of CEO Cho Yang-ho, is under investigation by South Korea's Transport Ministry for forcing the flight to taxi back to the terminal at John F. Kennedy International Airport after the junior attendant offered Macadamia nuts in a bag instead of serving the nuts on a plate, on Friday.

Witnesses told the Korea Times that Cho questioned the chief flight attendant over in-flight service standards and then, with the pilot's backing, ordered him off the plane.

The airline told the Korea Times that checking quality of service was one of Ms. Cho’s jobs, despite being a passenger at the time.

South Korea's Transport Ministry said Monday it will determine whether Cho’s behavior, which also included yelling at flight attendants and ordering the plane to stop, infringed on Aviation safety laws.
