Stewart International Airport (SWF) in Newburgh, NY is the budget-friendly alternative to JFK, LGA, and Newark for travelers in northern Westchester, Putnam, Dutchess, and Orange counties. With service from Allegiant, Frontier, JetBlue, and seasonal routes from other carriers, SWF often offers fares 30–50% below the NYC airports for the same destinations.
For northern Westchester travelers (Bedford, Mount Kisco, Yorktown, Peekskill, Mahopac), SWF can actually be CLOSER than JFK. From Yorktown Heights, SWF is 40 miles north via the Taconic and I-84 versus 50 miles south to JFK. From Mahopac, SWF is just 35 miles via the Taconic.
Routes from SWF historically include Allegiant to Florida (Orlando-Sanford, Punta Gorda, St. Pete), Frontier to Florida and the Carolinas, JetBlue seasonal routes, and seasonal European service (which comes and goes). Check current schedules at flyswf.com before assuming your destination is served.
