The airport is effectively served by one long building divided into 2 terminals. Orientation inside the terminals is easy and distances are shorter than at Suvarnabhumi Airport.
Even so, ideally arrive at the airport 2.5 hours before departure, especially because of the potentially long security lines, which can be as long as 40 minutes in the early morning or evening.
- Terminal 1: international flights
- Terminal 2: domestic flights within Thailand

Transfer between flights
Transfers are usually well and clearly organised, and if you have flights on one ticket or a pre-printed boarding pass, you don't need to leave the transit area.
The transfer usually takes no more than 30 minutes.
You always go through security and passport control when changing from an international flight to a domestic flight or vice versa.
