Trong, 65, took the new position after his predecessor Dang Tat Thang resigned as chairman and general director.
Trong served as the first deputy general director of Bamboo Airways from 2018.
In April this year, he was appointed vice chairman after a series of senior leaders were arrested for allegedly manipulating the stock market.
He has more than 40 years of working experience in the aviation industry and has held many senior management positions at major firms like Vietnam Airlines, Vietnam Airlines Engineering Company, Vietnam Air Petrol Company Limited and Noi Bai Airport Services JSC.
Bamboo Airways currently operates nearly 170 flights a day on 40 domestic and 12 international routes.
The carrier plans to continue launching new international services to tourism markets in Asia, Europe and Australia.
It also plans to increase its fleet to 35 by the end of this year and triple its fleet size to 100 aircraft by 2028.
