An airline official has been forced to apologise after his daughter had a crew member thrown off a plane in an argument over nuts.
Korean Air chairman Cho Yang-ho told reporters the 40-year-old's behaviour was "foolish" and that he regrets he did not raise her better.
The row happened after Cho Hyun-ah, who was travelling in first class, was offered macadamia nuts in a bag and not on a plate.
She found the flight attendant's actions so infuriating that she ordered the crew member's manager off the plane, calling him "incapable".
The aircraft was forced back to the gate at John F Kennedy airport in New York City, causing an 11-minute delay.
Her behaviour led to a public backlash in South Korea, with some accusing her of acting like princess and of being an international embarrassment to her country.
Korean Air initially apologised for inconveniencing passengers, but excused her outlandish behaviour.In a U-turn while speaking to the media, her father asked for the public's forgiveness.
Ms Cho has since stepped down from her role as head of the airline's cabin service, but has kept her other executive roles.
She has yet to apologise over the 5 December incident and is facing questions from the transport ministry over possible aviation law violations.
