Entering Bhutan
By Air:
Bhutan's national airline, Druk Air, is the only airline operating in Bhutan. All flights to Bhutan fly into Paro, which is the Kingdom's only airport. Flights to and from Kathmandu and Delhi take place three times a week. There are five flights per week to and from Kolkottta and Bangkok. During monsoons, unpredictable weather forces can delay flights and travelers are advised to include an extra day in their itinerary.

Bagdogra is the closest Indian airport to Bhutan. Flights from Kolkotta or Delhi to Bagdogra are available. From Bagdogra, one enters Bhutan at Phuentsholing, on the border of India and Bhutan. It is a 4-5 hour drive from Bagdogra airport to Phuentsholing on the border. Travel from Darjeeling or Gangtok (Sikkim) to Phuensholing will take about 7 hours. From Phuentsholing to Thimphu or Paro it takes approximately 6 hours.
