Terminal T1 was inaugurated in 2001 with a design capacity of serving 6 million passengers per year.
However, a two-fold increase in numbers of passengers in recent times forced the Airports Corporation of Vietnam (ACV) to upgrade the terminal.
The expanded project was built on 25,000 sq.m by ACV at a cost of VND500 billion. It included five departure and two arrival gates.
The same day, nearly 3,000 Jetstar Pacific passengers had their customs procedures cleared at the new expanded terminal.
Jetstar Pacific General Director Le Hong Ha said the new terminal helps save time for procedure clearance and improve the quality of services.
