Korean Air chairman and chief executive Cho Yang-ho has passed away at age 70 in a Los Angeles hospital.

The SkyTeam carrier states that Cho had been involved in the airline all of his life, with his father, Cho Choong-Hoon acquiring Korean Air in 1969. Cho junior was named its chairman and chief executive in 1999, and held the titles until his death.

He is survived by his wife, Lee Myung-hee, son (and Korean Airpresident) Walter Cho Won-tae, and daughters Heather and Emily.

Cho’s final months have been clouded by controversy, having failed to secure the required backing of shareholders to maintain his seat on Korean Air‘s board at its recent annual general meeting. Last year he was also indicted on charges of embezzling funds and tax evasion.
