There is no future for DSA as a commercial airport. The last new route that was added was Vilnius over 2 years ago. The place is a ghost town, becoming run down with absolutely zero maintenance of the facilities.
The work on the so called link road still hasn't started yet, despite being meant to last autumn, and there are now serious questions over funding.
I predict, within 5 years, DSA will not exist, unless there are some massive, massive changes.
