"This move represents a major step forward in our continued efforts to enhance service quality and passenger experience," the carrier said in a Facebook statement.
This will be the second Vietnamese carrier to operate at the terminal following Vietnam Airlines that began operations in late April.
Opened officially on April 19 with investment worth nearly VND11 trillion ($430 million), Terminal T3 is designed to handle up to 20 million passengers annually and around 7,000 passengers per peak hour, making it the largest domestic terminal in Vietnam.
The facility includes one basement and four above-ground floors, covering 112,500 square meters. It features 90 standard check-in counters, 20 self-service baggage-drop counters and 42 automated check-in kiosks, all integrated with Vietnam's national population database.
