Mae Fah Luang - Chiang Rai International Airport (IATA: CEI, ICAO: VTCT) serves Chiang Rai, the northernmost major city in Thailand. Named after Princess Srinagarindra, the mother of the late King Bhumibol Adulyadej, who was known as Mae Fah Luang (meaning 'Royal Mother from the Sky'), the airport is an important hub for tourism and trade in the upper northern region of the country. The airport handles both domestic and international flights, connecting Chiang Rai to Bangkok and select regional destinations in Southeast Asia. It serves as a key entry point for travelers visiting the Golden Triangle area, where Thailand, Laos, and Myanmar converge, as well as the surrounding hill tribe villages and cultural attractions. Upgrades and expansions have been undertaken over the years to accommodate growing passenger numbers driven by increasing tourism to Chiang Rai, particularly following the international attention the region received during the 2018 Tham Luang cave rescue.
