Long Island MacArthur Airport (ISP), originally established in 1942 as Islip Airport, is a public commercial airport located in Ronkonkoma, New York. Owned and operated by the Town of Islip, it covers over 1,300 acres and serves as a major alternative to New York City’s congested airspace for nearly 3 million local residents.

Today, MacArthur Airport operates as a regional transport hub, serving over 1.2 million passengers annually. It features a single-level main terminal, three active runways, and a dedicated Ground Transportation Center with direct access to the Long Island Rail Road (LIRR). It serves as a key access point for eastern Long Island—including the Hamptons and Fire Island—as well as the broader New York metropolitan region.
