There is only one way in which you can enter Bhutan:
By Air: Druk Air is the only airline operating in Bhutan. As Druk Air flights may be delayed because of weather in the monsoon (July & August), it is advisable to keep a 24-hour gap before any onward international connections.
Ace the Himalaya can assist you in arranging your Druk Air flights. For the Druk Air reservation, we would require your full names as in your passports. Drukair does not issue paper tickets, we will issue your Druk Air E-tickets and e-mail or fax them to you in advance.
