Chiang Mai International Airport (CNX) serves the city of Chiang Mai in Thailand. The airport sits at an elevation of 1,035 feet and lies approximately 3.1 miles from the city center, making it a quick and convenient connection point for travelers heading into Chiang Mai.

Air traffic through Chiang Mai International Airport reflects strong domestic connectivity within Thailand, linking the northern region of the country to its capital and other hubs. The airport primarily functions as a gateway for travelers moving between northern Thailand and destinations across the country, supporting both business and tourist travel within Southeast Asia. Its role centers on facilitating domestic air links rather than serving as a major international long-haul hub, positioning it as an important regional airport within Thailand's aviation network.

Given its elevation and location in a mountainous northern region of Thailand, travelers should be aware that terrain and local weather patterns in the area can influence flight conditions. The airport's proximity to the city, at just over 3 miles away, makes ground transportation straightforward for those arriving or departing Chiang Mai. As a regional airport supporting domestic routes, Chiang Mai International Airport plays a key role in connecting northern Thailand to the rest of the country's air transport system.
