Nok Air is a Thai low-cost airline headquartered in Bangkok, Thailand. Founded in 2004, the airline operates domestic routes across Thailand as well as select international routes to neighboring countries in Asia. Its name means 'bird' in Thai, and the airline is known for its colorful bird-themed branding and livery. Nok Air was established as a subsidiary of Thai Airways International, though it has since operated with greater independence. The airline focuses primarily on connecting Bangkok's Don Mueang International Airport with secondary cities throughout Thailand, serving passengers who seek affordable air travel. The carrier has faced financial challenges over the years, including restructuring efforts and impacts from the COVID-19 pandemic, which significantly reduced its operations. Despite these difficulties, Nok Air has worked to recover and maintain its position as one of Thailand's prominent budget airlines.
