Just wondering

I am from the outside looking in. I always wondered why Acadiana Regional Airport was so under utilized. It has the capabilities of landing some of the bigger jets flying today. To me it is a jewel in the ruff. ARA would have the capability of shutting down Lafayette Regional. Or is that the problem, a political one? There would be all sorts of possibilities that could be realized with an infusement of money to expand ARA; from freight, passenger, oil related, etc. It is such a waste. Can someone enlighten me as to why such an impressive asset is being wasted.
