Long Island MacArthur Airport (KISP) sits 50 miles east of midtown Manhattan in Ronkonkoma, Suffolk County. It handles modest commercial service (Southwest, Frontier, Allegiant, Breeze) alongside a substantial GA and charter community. For NYC-area private aviation, KISP is the eastern alternative to KFRG, particularly favored by charter routes connecting to the Hamptons and East End of Long Island during summer season.
The primary runway 6/24 is 7,001 feet — comfortably handling heavy and ultra-long-range jets with typical loads. Hampton Jitney's KISP-to-East-Hampton ground connection and the helicopter shuttles from KISP to KHTO make the airport a structural staging point for the summer Hamptons run, particularly Thursday-evening eastbound and Sunday-evening westbound. ExcelAire and Sheltair are the two principal FBOs. Field elevation is 99 feet, no density-altitude concerns. The dominant operational considerations are northeast winter weather (snow, freezing rain, occasional ramp closures) and the summer Long Island convective pattern. Ground time to East Hampton via the Sunrise Highway is 90 minutes by car; Montauk is 120 minutes; helicopter from KISP to East Hampton is 25 minutes. Midtown Manhattan via the Long Island Expressway is 90–120 minutes depending on traffic.
