Following a senior management shake-up that saw its chief executive and commercial chief step down, Cathay Pacific has also appointed a new head of its low-cost subsidiary HK Express.

Cathay veteran Mandy Ng, who has been with the operator for 17 years, takes over as HK Express chief executive with immediate effect, following the departure of Ronald Lam to the post of Cathay chief customer and commercial officer.

Ng began her career at Cathay as a management trainee in 1999, before working in planning, revenue and sales departments within the airline. She was most recently general manager of business development at Swire Pacific. Swire Group wholly owns Cathay Pacific.

Former Cathay chief Rupert Hogg and former customer and commercial chief Paul Loo disclosed their resignation on 16 August, amid mounting scrutiny of the airline from China.

Hogg is succeeded by Augustus Tang, who has been with the Swire Group since 1982 and was most recently chief executive of Hong Kong Aircraft Engineering Company (HAECO), a post he held since November 2008.
