Thai AirAsia CEO Santisuk Klongchaiya said: “Thai AirAsia will be the only airline offering direct flights between Bangkok and Hai Phong, further solidifying our position as the airline with the most direct routes to Vietnam. With this addition, we now connect Bangkok to six Vietnamese cities. Based on the strong demand for our existing Vietnam routes, which saw an average load factor of 90% in the first two months of 2025, we expect a fantastic response from travellers for this new route as well,” Santisuk added.
Located in northern Vietnam, Hai Phong is a dynamic coastal city known for its cool climate, local food scene, and easy access to the world-famous Halong Bay — just a 50-minute drive from the airport.
Thai AirAsia currently operates direct flights from Bangkok to six cities in Vietnam, comprising Hanoi (21 flights per week), Ho Chi Minh City (21 flights per week), Danang (21 flights per week), Nha Trang (seven flights pe week), Phu Quoc (seven flights per week), and Hai Phong (four flights per week).
