Chiang Mai International Airport (CNX/VTCC) is the main commercial airport serving Chiang Mai, Thailand's second-largest city and the cultural capital of the north. Located approximately 3 kilometres southwest of the city centre, it handles both domestic and international traffic and serves as an important regional hub. The airport is operated by Airports of Thailand (AOT) and has undergone multiple expansions to meet growing tourism demand. It serves direct routes to major Asian cities including Bangkok, Singapore, Kuala Lumpur, Hong Kong, and several Chinese cities. Chiang Mai is a major gateway for tourists exploring northern Thailand's temples, mountains, and trekking routes. Passenger traffic has historically exceeded 10 million annually in peak years, though figures fluctuated significantly during the COVID-19 pandemic.
