Long Island MacArthur Airport

Long Island MacArthur Airport in Ronkonkoma serves central Long Island — the Islip area and the middle of Suffolk County. It carries a modest amount of commercial service alongside business and general aviation, and for charter it's a practical field for travelers in the center of the Island.

Who flies here

ISP mixes light commercial service with private and corporate traffic. Its general-aviation side gives Long Island travelers a mid-Island departure point without routing through the New York City airports.

On the field

As of mid-2026 the FBO at MacArthur is Modern Aviation, which took over the field's longtime Sheltair operation in 2022, handling private-aviation ground services on the general-aviation side.

A bit of history

The Town of Islip established the airport in 1942, and it began commercial operations in 1960. Named for General Douglas MacArthur, it has grown into central Long Island's regional airport while keeping a busy general-aviation presence.

FBO and history details were last verified mid-2026 against the airport's and operators' own published information; tenants and amenities change, so confirm the departure terminal with your operator.
