Buddhist calendar
The first Airbus A319 arrived in Bhutan on 19 October 2004; the date chosen after a Buddhist astrologer was consulted to ensure the aircraft arrived in Bhutan on an auspicious day in the Buddhist calendar. Before entering service on commercial flights on 31 October 2004, Drukair took their A319 on a country-wide flight in honour of the ascension of Crown Prince Jigme Khesar Namgyel Wangchuck to the Chhoetse Penlop. The second aircraft was delivered by Airbus to Drukair in December 2004. On 31 August 2012, Druk Air took delivery of a third Airbus A319.
