Travel by Air
The country has so far only one international airport that caters to the needs of visitors coming in through flight. Bhutan has two carriers – Drukair and Bhutan Airline. As flights can be delayed due to weather conditions (particularly during the summer months), it is advisable to allow at least 3-4 hours transit time before connecting to or from a Drukair/ Bhutan Airline’s flight.
The following stations are connected with Bhutan Flights:
India (Kolkata, New Delhi, Bagdogra, Mumbai, Gaya, Guwahati)
