Actually. What you could envision is massive International AND Domestic airline with its corporate hub based in Newburgh. With round trips regularly to Miami, Las Vegas, LA, London, Paris, Moscow. All avoiding the bull shit of JFK which is probably just as long to get to...from the city on some days....
Add in a helicopter taxi service for anyone who wants it and your golden...because Baltia limo service will be full..
Seriously, you could actually redefine traveling to and from New York...
