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 two jet bridges. The departures hall is on the second floor, while the arrivals hall is on the first floor as well as a foreign-exchange kiosk. The terminal is connected to a large parking lot.
