The great untapped air market is in the other direction…Trenton Mercer. It's right on the West Trenton SEPTA R3/NJ Transit proposed West Trenton line. Again, some shrewd marketing, somewhat frequent service, and a few shuttle buses, and you're in business. No need to ask if you build it, will they come?
The re-working of the airspace does not significantly eliminate the frequent conflicts between the approachs and departures for Westchester and Islip and LGA, JFK and EWR. Even LGA and EWR and JFK and LGA conflict with each other for some wind directions. Trenton conflicts with PHL and to some extent EWR. Stewart is much less of a conflict.
Westchester, Islip and Trenton's longest runway is not much more than half the length of Stewart's longest, and thus cannot accommodate many larger aircraft types.
The proper continued and needed role for Westchester, Islip and Trenton is to be a reliever airport for the larger facilities and handle private, corporate, charter and commuter airline flights.
Of all the airports in the NY-PHL region, only Stewart has the capability of becoming a major airport as it is not constrained by runway length and is less of a conflict for air traffic control purposes.
That is why the rail connection to Stewart can be a very viable means of providing needed additional long-haul air capacity in the region.
