There were both in the domestic and international sectors, between which there is a free bus. It's clean, there are a lot of people, but there are no crowds. There are many places for food and snacks, shops, seats.
The arrival area is on the ground floor, the departure area is on the second floor. There are many taxis in the arrival area, there are trolleys, simplified controls, navigation in Vietnamese/English. There are self-check-in counters for some local airlines in the departure area. The queue for security and passport control is frequent. There are business halls.
Location from the city, 10-20 minutes drive to the outskirts.
A small airport, like all Asian airports in small countries. But everything is there :) clean, comfortable, impossible to get lost :) in general, nothing special
