Thimphu is served by the only international airport of Bhutan, Paro Airport, which is about  away by road. Druk Air had its headquarters in Thimphu but now there is only a branch office. Druk Air is one of only two airlines flying into Bhutan excluding charter flights by Buddha Air and is a lifeline with the outside world for the Bhutanese people, also supporting emerging inbound tourism and export markets. The airline has in recent times been criticised for its unreliability, particularly from the Bhutanese tourism industry which is still in its infancy, and regards the very company upon which it relies as its biggest threat. Tashi Air is a private airline recently launched in the country.
