It is a major gateway that links Northern Thailand to the rest of the region and is currently the fourth-busiest airport in the country. The airport is at an elevation of 316 meters (1,037 ft) above mean sea level. It has one runway designated 18/36 with an asphalt surface measuring 3,100 by 45 meters (10,171 ft × 148 ft). There are two terminals, one for domestic passengers and the other for international flights
As a result of the temporary closure of Suvarnabhumi Airport in 2008 due to the protests, Chiang Mai became the alternative stop-over for China Airlines' Taipei-Europe flights and for Swiss International Air Lines' Singapore-Zurich flights in the interim. On 24 January 2011, the airport became a secondary hub for Thai AirAsia. The China Airlines flights are now regular flights.
The Airports of Thailand expanded the terminal with upgrades in 2014 including expansion of the apron for larger planes, extending operating hours to 24/7 (effective April 2014), and enlarging the international arrival hall and domestic departure hall. As of 2018, 31 airlines operated at CNX, serving 11 million passengers, 78,210 flights and 14,612 tons of cargo.
