The fact that matter is, it is not the airport that can get people to come, it has to be the aviation policy that can help. If there is lack of bilateral agreement between a pair of country, it doesn't matter if the airport is built with gold, no one can fly there.
Agreed..........but also a lot of factor, NOT only airport management company, airlines company, other support facility company........etc, basic your infra-structure materials.....ground works should do it very well too.
