Serving Khon Kaen, a city strategically important for the region's infrastructure both geographically and economically, the airport was upgraded to international standards in 2005 with the opening of a new terminal. It is a few kilometres west of downtown.
The airport is equipped with one jet bridge. The departures hall is on the second floor, which also houses some small shops selling food and gifts, while the arrivals hall is on the first floor as well as a foreign-exchange kiosk. There is a small restaurant on the third floor. The terminal is connected to a large parking lot.
