Entry to Bhutan
The most convenient way of entering Bhutan is by Druk Air, the country's national (and so far only) carrier. As flights can be delayed due to weather conditions (particularly during the summer months), it is advisable to allow 24 hours before any onward connection.
Druk Air flies regularly between Bhutan and the following countries:
Bangladesh ( Dhaka ); Burma ( Yangon ); India (Kolkata, Delhi ); Nepal ( Kathmandu ); Thailand ( Bangkok )
Arrival/departure by land is also possible, through the southern border town of Phuentsholing . The nearest airport is at Bagdogra, West Bengal , about 4 hours drive away. Phuentsholing is a convenient entry/exit point for travelers wishing to visit the Indian states of Sikkim and West Bengal along with Bhutan .
It is sometimes possible to arrange land exit from Bhutan through the southeastern border town of Samdrup Jongkhar , which is approximately 3 hours drive from Guwahati, capital of the Indian state of Assam.
