Walter Cho is the chairman and chief executive officer of Hanjin Group and Korean Air.

[1] He attended a two-year college in the United States before transferring to Inha University in South Korea in 1998.

[1] He became the vice-president of Hanjin Information Systems & Telecommunication, and then in 2004 was transferred to Korean Air, where he became the vice-manager of the planning team within the operations and strategy department.

[2] In 2015, the aftermath of his sister Heather's resignation over the nut rage incident, he took over management responsibility for other areas of Korean Air's business which she had previously overseen, including hotels and catering, in what was widely seen as a confirmation that he would inherit control of the company.

[10] Cho concurrently held a number of other posts at Hanjin Group affiliates, including Hanjin Kal, Jin Air, Uniconverse, and the aircraft ground handling company Korea Airport Service, but resigned from those positions in 2017, in a move which Korean Air stated would improve management efficiency within the company.

[23][24] He also joined employees and executives to manually clean and disinfect an aircraft in an event to assure the public of cabin safety amid the pandemic.
