Long Island MacArthur Airport (ISP)

Located in Ronkonkoma, Suffolk County, Long Island MacArthur Airport (ISP) is a dynamic regional hub owned and operated by the Town of Islip. For many Long Islanders, ISP serves as the most convenient and stress‑free option – offering easy access, fewer delays, and a relaxed travel experience compared to busier New York‑area airports.
Originally established as Islip Airport in the early 1940s as a military airfield, MacArthur transitioned into commercial service in 1960. Over time, it has earned a reputation for reliability and convenience – handling over 1.36 million passengers annually in 2024, with daily traffic averaging more than 5,000 travelers.
While smaller in scale, ISP provides nonstop service via airlines such as JetBlue, Southwest, Frontier, Breeze, Avelo, and Cape Air—connecting Long Islanders to major U.S. cities and nearby sun destinations in the Southeast, Florida, New England, and beyond. This makes ISP a favorite for residents seeking domestic convenience and a calmer airport experience.
The airport is slated for a major transformation: a new north terminal connected directly to the Ronkonkoma LIRR station via pedestrian walkway, supported by $150 million in state funding, plus substantial county and local investment to enhance access, infrastructure, and future growth.

Terminal & Passenger Experience
The original terminal (built in 1966) received expansions in 1990 and again in the 2000s, including Southwest Airlines’ $65M concourse addition. Despite challenges during that construction, the terminal today features straightforward design, modest amenities, and efficient layouts for quick turnaround.
Travelers will find a no-fuss atmosphere with essential dining, newsstands, car rental desks, and charging stations. The relaxed environment and limited crowds translate to shorter security lines and streamlined boarding.
Growth & Modernization Ahead
A major evolution is underway:
- New North-Side Terminal Project: ($3.3B in phases) with eight initial gates connected via pedestrian bridge to the Ronkonkoma LIRR station. Supported by $150M state + $50M local investment for roads, sewers, and rail connection infrastructure.
- Amtrak Expansion: Plans for a Northeast Regional route terminating at Ronkonkoma Station by 2028 would provide direct rail service between ISP and many East Coast cities.
