Druk Air Royal Bhutan Airlines (KB) (Bhutan)
Druk Air is probably the smallest national airline in the world. They currently fly from Bangkok to Paro every day of the week. Most flights operate via Kolkata (India) or Dacca (Bangladesh). Their Airbus A319 is pretty new so you will fly very comfortably. On your flight to Bhutan make sure you get a window seat. If you sit on the right you can even see Mt Everest. And the final approach into the Paro Valley is pretty stunning too. The Business Class is good value too.
Please note that Druk Air flights are not available for booking on our website. If you wish to book these flights, please contact us by email. However, before you book these flights, make sure you familiarize with the visa requirements of Bhutan. You will only be allowed to board the flight to Bhutan if you can show a visa approval letter. And you will also get this letter if you have booked a package tour in Bhutan.
