Well considering that in the history of FT and its many millions of posts there have been few if any posts lamenting the lack of ervice to Pakistan by any carrier I would think that it is not a place in great demand by most passenegrs and not by most mainline western carriers. It is directly attributable to ploitical and economic stuation in the country, not to mention that most of the expat communities that you speak of generally do not fly upfront.
