Her walk of shame came after her father, the chairman of Korean Air, also apologised for the behaviour of his adult daughter, saying he regretted he hadn’t raised her better.

Cho Yang-ho made a deep bow before journalists in response to simmering public anger over his daughter’s brattish behaviour.

Cho Hyun-ah, who was head of cabin service at Korean Air, was angered when a flight attendant in first class offered her macadamia nuts in a bag, not on a plate.

She ordered a senior crew member off the plane, forcing it to return to the gate at John F Kennedy airport in New York City.

Cho Yang-ho called his daughter’s behaviour foolish and says he regrets he didn’t raise her better.

“It’s my fault,” he said of the December 5 incident. “As chairman and father, I ask for the public’s generous forgiveness.”

Cho Hyun-ah wore a long black coat and looked nervous as she appeared in public for the first time since the revelations about her behaviour became known.

“I sincerely apologize. I’m sorry,” she said in a trembling voice.

She made the apology outside the offices of the Aviation and Railway Accident Investigation Board where she was due to be questioned about the incident.

Her actions caused uproar in South Korea and abroad.

South Korean media called the 40-year-old a princess and some Koreans said she was an international embarrassment to her country.

Korean Air had earlier excused her behaviour even as it apologised for inconveniencing passengers.
