"Cathay Pacific fully supports Hong Kong's implementation of the 'One Country, Two Systems' principle and we have full confidence in Hong Kong's bright future," said John Slosar, chairman of Cathay Pacific, in the statement.

Around half of a month ago, one of the airline's pilots was permitted to fly despite being charged with rioting by Hong Kong authorities. And staff members also revealed travelers' information, posing a serious threat to aviation safety.

Such incidents have made the Civil Aviation Administration of China issued a warning of major aviation safety risks to Hong Kong airline Cathay Pacific, listing three requirements for Cathy Pacific in the warning letter.

Cathay is based in China's Hong Kong Special Administrative Region (HKSAR), with frequent flights in and out of the Chinese mainland and also a large number of routes to Europe and the United States that pass through that airspace. 

The airline's largest shareholder is Swire Pacific Ltd., with a 45 percent stake, followed by China's flagship carrier, Air China Ltd., which owns 30 percent, according to the airline's latest annual report.

Hogg became the CEO of Cathay Pacific on May 1, 2017. He is also chairman of Hong Kong Dragon Airlines Limited, AHK Air Hong Kong Limited, a director of John Swire and Sons (HK) Limited, and Air China Cargo Company Limited. 

According to Cathay Pacific's website, Hogg joined the Swire group in 1986 and has worked with the group in Hong Kong, Southeast Asia, Australia and the United Kingdom.
