Bhutan has a policy of allowing only a limited number of tourist per year into the country.
So unless they are willing to let Druk Air suffer due to the increased competition or are looking to allow in more tourist, why would they allow anyone to fly there?
I have seen pictures of Bhutan, if they are willing to open up, there will be no shortage of tourist. Which means more people will be wanting to fly into Paro.
As for fitting up Paro with lights, navaids etc, what an excellent idea.
