The country has so far only one airport that caters to the needs of visitors coming in through flight. Bhutan's only international airport at Paro is located at a height of 7300 ft above sea level and surrounded by mountains and hills as high as 16,000 feet. Druk Air is the national airline which was started in 1981, April 5, operates with three Airbus and 1 ATR. It flies to destinations that include Bangkok, Singapore, Katmandu, Dhaka, Delhi, Kolkata, Bodh Gaya, Bagdogra, and Guwahati in India.
Bhutan is a private airline that was commenced on 7 December 2011. The route is pretty similar to Druk air and also they use a similar airbus.
The flight into Paro International Airport is one of the most spectacular landing in the world.
