'Nut Rage' Airline Exec Resigns (Partially) Heather Cho of Korean Air loses some of her duties By John Johnson, Newser Staff Posted Dec 9, 2014 4:07 PM CST 28 comments Comments A file photo Cho Hyun-ah, or Heather Cho. (AP Photo/Yonhap) (Newser) – A Korean Air exec whose temper tantrum about macadamia nuts has become an international story resigned from some of her duties today, reports CNN. Heather Cho, daughter of the airline's CEO, will still be a VP of some sort, but she'll no longer oversee operations including cabin service. That's what got her in trouble: When a flight attendant offered her macadamia nuts in a bag instead of on a plate, Cho reportedly berated the chief flight attendant for failing to have his crew follow protocol for first-class passengers, then ordered the pilot to return to the gate at JFK so the chief attendant could be removed from the plane. As a result, the plane took off about 20 minutes late. “I am sorry for causing trouble to the passengers and the people,” said Cho in a statement. “I seek forgiveness from those who were hurt by what I did.” The 40-year-old's apology and partial resignation might not be the end of it, however. Authorities are investigating whether forcing the plane back to the gate when there was no emergency subjects Cho to fines or worse for violating air-safety regulations, reports the Christian Science Monitor. A South Korean civic group plans to file a complaint with prosecutors.
