Vietnam’s Aviation Backbone and Economic Connector
The Hanoi–Ho Chi Minh City route has consistently been a standout in Vietnam’s aviation landscape, making its mark as one of the top 10 busiest domestic routes globally since 2017. With the presence of five airlines (Vietnam Airlines, Vietjet, Bamboo Airways, Pacific Airlines, Vietravel Airlines), passengers have a wide variety of choices to make to fly with comfort and satisfaction in air services.
Beyond its role as a domestic flight route, the Hanoi–Ho Chi Minh City route is a crucial economic connector, facilitating trade and mobility while contributing significantly to Vietnam's development./.
