Druk Air, officially known as the Royal Bhutan Airlines, is the flag carrier of the Kingdom of Bhutan. Established in 1981 and commencing operations in 1983, it holds a monopoly on scheduled international air services to and from Bhutan, operating out of Paro International Airport. The airline serves destinations across South and Southeast Asia, including cities in India, Nepal, Thailand, Singapore, Bangladesh, and beyond. Its operations are closely tied to Bhutan's regulated tourism policy, which limits visitor numbers to preserve the country's cultural and environmental heritage. Druk Air is state-owned and plays a critical role in Bhutan's connectivity given the country's landlocked and mountainous geography. Flying into Paro is considered one of the most challenging approaches in commercial aviation, requiring specially trained and certified pilots.
