# Long Island MacArthur Airport

Long Island MacArthur Airport (IATA: ISP, ICAO: KISP, FAA LID: ISP), formerly known as Islip Airport, is a public airport in Ronkonkoma, New York, within the Town of Islip in Suffolk County, on Long Island. Covering 1,311 acres (531 ha), the airport was established in 1942, activated in 1943, and began serving as a commercial airport in 1960. It has three runways and two helipads.
Owned and operated by the Town of Islip, MacArthur Airport serves Nassau and Suffolk counties as an alternative to John F. Kennedy and LaGuardia airports – both of which are located in the Borough of Queens in New York City. Shuttle buses connect the airport to the Long Island Rail Road's Ronkonkoma station.
The Federal Aviation Administration (FAA) designated LIMA an Official Metro Airport in early 2011, meaning it is now grouped with LaGuardia, Kennedy, and Newark in travel and informational searches for New York airports, thus providing better exposure. MacArthur Airport does not share the congested airspace of the city-centric airports, and it has an exceptional record of on-time performance. In 2009, 83.6% of flights arrived on time and 85.6% of flights departed on time.
In 2016, it had 124,154 aircraft operations, an average of 340 per day; 84% general aviation; 7% scheduled airline; 6% air taxi and 2% military. In 2024, the airport served more than 1.36 million airline passengers. In July 2018, 247 aircraft were based at Islip: 141 single-engine, 30 multi-engine, 36 jets, 31 helicopters, and 9 military. The town-owned Foreign Trade Zone is next to the airport property.

## History
### Early years

In April 1942, the Town of Islip contracted with the federal government to build an airfield on town-owned land for military use. Within months, the Civil Aeronautics Administration – the predecessor to today's Federal Aviation Administration – funded the construction of the airport and three paved runways through the federally-funded Development of Landing Areas for National Defense (DLAND) program. Originally named Islip Airport, at the suggestion of Charles H. Duryea – a local elected official, the airport was renamed MacArthur Airport after U.S. Army General Douglas MacArthur, whose dramatic escape from the Philippines during World War II had captured the attention of the world. The airport was officially activated in May 1943.
In 1944, Lockheed Aircraft Corporation built the first hangar at the airport. Five years later, the Town of Islip built the airport's first terminal building, in preparation for airline flights. Through the 1950s, the Sperry Corporation conducted aerospace research at the airport.
In 1947, the Town of Islip offered the airport to the Port of New York Authority (which is today the Port Authority of New York and New Jersey). The offer was rejected by the authority because of the airport's location outside of the port region.

### Commercial service era

In 1960, Allegheny Airlines was the first scheduled passenger airline at Islip, flying to Boston, Philadelphia, and Washington, D.C. The March 1961 Official Airline Guide lists five weekday Convair 440 departures: a nonstop to Washington National, one to Baltimore, and three flights direct to Boston via several stops. The General Douglas MacArthur Terminal was completed in 1966. In 1967 Mohawk Airlines began two Fairchild Hiller FH-227 flights a day, to Bridgeport and Albany and beyond with one flight continuing to Toronto. By 1969 Mohawk was flying BAC One-Elevens nonstop to Syracuse. In 1972 Mohawk had nonstops to Albany with direct service to Buffalo and Rochester. Mohawk would soon be merged into Allegheny Airlines.
In 1971, American Airlines began flying nonstop Boeing 727-100s to Chicago O'Hare Airport. By 1974 Allegheny had started BAC One-Elevens and McDonnell Douglas DC-9-30s nonstop to Albany and Ronald Reagan Washington National Airport, and direct jets to Burlington, Vermont, Cincinnati, and Detroit. Allegheny continued operating Convair 580s nonstop to Albany, Boston, Bridgeport, and Washington, D.C., in addition to direct Convair 580s to Buffalo and Rochester. Allegheny would be renamed USAir, which then became US Airways, with these respective airlines operating service into the airport for many years before US Airways was merged into American.
The Official Airline Guide (OAG) shows the following passenger jets to Long Island MacArthur nonstop from the following at various times from the late 1960s to the late 1990s, with types:

A number of commuter and regional airlines served the airport from the late 1970s to the late 1990s, including Allegheny Commuter, Altair Airlines, Atlantic Coast Airlines operating as United Express, Business Express Airlines operating as Delta Connection, Continental Express, Empire Airlines (1976-1985), Mall Airways, Metro Airlines Northeast operating as Trans World Express, Mohawk Airlines (a later commuter air carrier version), NewAir and its predecessor New Haven Airways, Piedmont Regional Airlines operating on behalf of Piedmont Airlines (1948-1989), Pilgrim Airlines, Precision Airlines operating as Northwest Airlink, Ransome Airlines and USAir Express and its successor US Airways Express. According to the OAG, prop types operated by these smaller airlines to the airport included the ATR-42, Beechcraft 99, Beechcraft 1900C, BAe Jetstream 31, de Havilland Canada DHC-6 Twin Otter, de Havilland Canada DHC-7 Dash 7, de Havilland Canada DHC-8 Dash 8, Dornier 228, Embraer EMB-110 Bandeirante, Nord 262, Piper Navajo, Saab 340, Short 330, Short 360 and Swearingen Metro.
In 1989, construction of two small, four-gate concourses connected to the existing terminal building commenced. The project was completed in 1990; the two concourses included the first jet bridges installed at the airport.
In 1994, Continental Express was operating ATR-42s nonstop between the airport and the Continental Airlines hub at Newark Airport. By 1999, Atlantic Southeast Airlines (ASA) flying as Delta Connection was operating Canadair CRJ-200s nonstop to the Delta Air Lines hub in Atlanta while Comair, also flying as Delta Connection, was operating Canadair CRJ-200s nonstop to Delta's hub in Cincinnati. Also in 1999, Continental Express was flying Embraer ERJ-145s nonstop to the Continental Airlines hub in Cleveland. Southwest Airlines also arrived at Islip in 1999, with nonstop Boeing 737-700s to Baltimore, Chicago Midway Airport, Nashville, and Tampa.
In the early 2000s, Continental Express continued to serve the airport with nonstop regional jets to Cleveland while Continental Connection scheduled nonstop turboprops to Albany, New York; both services ended in 2005. Spirit Airlines scheduled flights to several Florida cities and Detroit, before moving to LaGuardia Airport in 2001; in May 2008 the airline resumed service to Fort Lauderdale from MacArthur, but dropped it shortly thereafter. Delta Express, which had nonstops to Orlando and Fort Lauderdale, dropped MacArthur Airport in 2003 after a decline in traffic. Delta Connection regional jet service to Atlanta flown by Atlantic Southeast Airlines (ASA) on behalf of Delta Air Lines ended on May 1, 2008, following a mid-April announcement that Delta and Northwest Airlines were planning to merge – a move that led to changes for the merged airline.
Following the September 11, 2001 attacks, MacArthur Airport saw a 25% decrease in passenger traffic. Passenger traffic later increased, but they decreased again in 2006. Charts depicting annual operations and passenger boardings are in Appendix C and D. In 2005 MacArthur Airport had 173,135 total operations; during this year 1,055,832 passenger were enplaned, 7.07% more than 2004. In 2006 MacArthur had 189,390 total operations with 1,138,061 passenger boardings. The year 2007 brought total operations at MacArthur down to 184,760 but passenger boardings increased to 1,167,515, MacArthur's highest boardings in the last 6 years. In 2008, total operations at MacArthur were 179,230 and passenger boardings were down to 1,048,768; in 2009, 159,736 total operations and 929,902 passenger boardings. From 2005 to 2009 almost every category of MacArthur's operations has declined: airline, military, air taxi, and general aviation. A figure was released in the 2010s citing a 46.4% decrease from 2007 to 2012, the most loss in any small hub airport. The figures rose back up as the decade progressed, but temporarily dipped down again in 2020 due to COVID-19. By 2023, the figures had again increased, with 1,278,000 passengers recorded that year.
In 2004, MacArthur Airport embarked on an expansion that included a new, Gensler-designed Southwest Airlines terminal built by the airline at a cost of $65 million. Phase one of the expansion included four gates to be used by Southwest, as well as space for shops and restaurants. Phase two, completed in November 2006, added four more gates for a total of eight new gates. Prior to the expansion project, passengers had to pass back through the ticketing area of the airport to reach the baggage claim area. With the completion of Phase two, the new concourse provided a more convenient exit point to baggage claim, ground transportation, and the airport's roadway exit. Nevertheless, the location of the baggage claim area still requires most travelers using the airport's long-term parking lots to pass back through the ticketing area of the airport to reach their vehicles. The construction of the 2004 expansion caused a scandal when it was discovered that the new concourse was built without the needed approvals from New York State and with numerous violations.
The then-Suffolk County District Attorney Thomas J. Spotta, who was involved in the investigation of the scandal, stated that large portions of the new concourse were in violation of fire and safety codes, causing risks to public safety. Violations included the main electrical control room being built with improperly-placed fire sprinklers, creating an explosion risk – and natural gas pipes being constructed right below the terminal's air conditioning intake manifolds, creating a risk for gas entering the terminal through its ventilation systems in the event of a gas leak. Town officials eventually pled guilty to corruption charges in connection to the scandal, and work was done to rectify the violations and bring the terminal up to all safety and fire codes.
A major proponent of the airport's 2004–2006 expansion projects was Peter J. McGowan, then the Islip Town Supervisor; the new concourse was named after McGowan. The terminal was renamed the Veterans Memorial Concourse in homage to Long Island's distinction as home to more military veterans than almost any other community in the United States.
In late September 2007, Ryanair, an ultra-low cost airline based in Ireland, proposed to fly between MacArthur Airport and its hub in Dublin, Ireland. The proposal was ultimately called off.
A new control tower was completed in 2010 and opened in 2011 to replace the tower built in the early 1960s, which had become functionally obsolete and had fallen into disrepair. In 2010, construction also began on a new Fuel Farm, which would the open the following year and increase the airport's jet fuel supply; it was built through a partnership between the Town of Islip and Southwest Airlines. Soon thereafter, the roadway in front of the terminal was reconfigured; another taxiway was also constructed along with other projects using FAA airport improvement program funds. Development of the West Side, home to a thriving general aviation sector, was to be underway in late 2010.
While the airport continues to expand it has added numerous amenities, including free courtesy cell phone parking. In November 2009, MacArthur Airport became the only airport in the tri-state region to offer free wireless Internet service in the entire terminal and in the courtesy cell phone parking lot. In addition, the airport launched several tools designed to provide up-to-date information to travelers, including its first official website, flyLIMA.com.
In 2014, the airport opened an international arrivals & U.S. Customs facility for private plane passengers, which is able to accommodate non-U.S. Citizens.
In January 2016, plans were announced to build a U.S. Customs Station at MacArthur Airport for commercial flights, with help from financial assistance from New York State Governor Andrew Cuomo – an attempt at making MacArthur an international destination and at enticing airlines to add MacArthur to their destinations; the proposal had been discussed for a number of years by local, state, and federal officials. A marketing campaign for the airport was soon launched by the Town of Islip, including through advertisements on public transportation, digital marketing, and radio spots. Additionally, a new logo and slogan were unveiled.
Allegiant Air previously operated two weekly flights on a seasonal basis to Fort Myers/Punta Gorda, Florida using McDonnell Douglas MD-80s but no longer serves the airport. PenAir began operating two daily nonstop flights to Boston in July 2013, but stopped flying to MacArthur a year later. The last legacy carrier to serve Islip was American Airlines with Embraer ERJ-145 code share flights operated by its American Eagle Airlines regional affiliate Piedmont Airlines to Philadelphia. Service to Washington–National ended on July 2, 2014, after the merger between US Airways and American. The newly merged airline had to cut service to 17 cities from Washington–National because of an antitrust lawsuit preventing the airline from monopolizing slots at National Airport. American Airlines reapplied for nonstop service between MacArthur Airport and Washington–National when two slots opened up, but the airline lost the bid for both in early 2015.
In January 2017, the airport was used as the landing location for the aircraft carrying Joaquin "El Chapo" Guzman to New York with law enforcement agents for his prosecution, following his arrest and extradition to the United States from Mexico.
On July 17, 2017, Frontier Airlines announced service to 10 new cities using aircraft as large as the Airbus A321, which approaches the Boeing 757 in range and passenger capacity – a first for the airport in that past decade. Breeze Airways began service to and from the airport in 2022 and added additional routes in 2023.
In 2020, a new general aviation hangar opened at the airport. Ground was also broken that year on a new intermodal transportation facility.
In September 2022, American Airlines ended service to Islip citing a regional pilot shortage as the main reason behind the cut. Also taking place in 2022 was the opening of a new ground transportation center at the airport. This facility houses all of the rental car agencies present on-site at the airport. As of December 2022, Southwest operated year-round, non-stop service to Baltimore, Fort Lauderdale, Orlando, Tampa, Nashville, and West Palm Beach.
In February 2023, the airport property was designated as a superfund site due to chemicals being detected in the soil and groundwater; negotiations between the New York State Department of Environmental Conservation and the Town of Islip soon started, with both parties working to ensure the site's cleanup.
Also taking place in February 2023 was the commencement of a major, $26 million terminal renovation project. The Airport received an additional $2.7 million in federal funds for further terminal renovations that June.
In February 2024, the Federal Aviation Administration approved the Town of Islip's plan to erect a new terminal on the north side of the airport, to be built as part of the Midway Crossing project. The $3.3 billion project will consist of a new terminal and parking facilities; the new terminal will be directly connected to the Ronkonkoma Long Island Rail Road station via a pedestrian walkway. The first phase of the terminal's construction will see the construction of eight gates.
In June 2024, JetBlue announced that it would commence service at MacArthur Airport, with flights set to begin that October. The airline's service at MacArthur Airport, by the end of 2024, became profitable faster than at any other airport it served.
On January 15, 2025, JetBlue announced in that it would begin operating seasonal daily non-stop service between Islip and Logan International Airport in Boston, Massachusetts, starting that April.
On March 11, 2025, Avelo Airlines announced service to MacArthur Airport, with flights beginning that May.

### Terminal

MacArthur Airport’s original terminal opened in 1966. The terminal was expanded between 1989 and 1990, with the creation of two concourses with two gates each. In 2004, construction commenced on the current terminal through an expansion and renovation project funded by Southwest Airlines; the terminal expansion was built off and replaced portions of the existing 1966 terminal, while other, existing portions were renovated.
Additionally, the radio station WRCN-FM maintains its offices and studios within the airport.

### Air navigation

MacArthur Airport has a 158-foot (48 m) control tower, located on the south side of the airport. The tower, which replaced one built in the early 1960s, was built at a cost of roughly $20 million (2010 USD) and includes a 525-square-foot (48.8 m$^2$) control cab.
The airport is also equipped with an Automated Surface Observing System (ASOS) for weather forecasting, in addition to having an Automatic Terminal Information Service (ATIS).
Furthermore, the New York Air Route Traffic Control Center (ZNY) – known as an ARTCC for short – is located on the grounds of the airport.

MacArthur Airport is connected with the Long Island Rail Road's adjacent Ronkonkoma station by shuttles and taxi service. The LIRR offers passengers transportation to nearby New York City. Additionally, Amtrak's Northeast Regional will begin serving the Ronkonkoma LIRR station – and thus the airport – in or about 2028, providing MacArthur Airport with inter-city rail service.
The Central Islip and Patchogue stations are also accessible from the airport, via Suffolk County Transit's Route 6 bus route.

## Future developments
### New terminal

A new passenger terminal will be constructed on the north side of the airport. The project will see the erection of a new airport terminal and parking facilities; the new terminal will be directly connected to the Ronkonkoma Long Island Rail Road station via a pedestrian walkway. The first phase of the new terminal's construction will include the construction of eight gates, in addition to a new, adjacent apron and taxiways linking the new facility with the existing taxiways and runways.
In February 2025, New York state announced it is investing $150 million into the construction of the pedestrian connection between the train station and new airport terminal.

### Amtrak service

In January 2025, it was announced that Amtrak will establish a new Northeast Regional route on Long Island, terminating at the Ronkonkoma LIRR station, thus providing MacArthur Airport with inter-city rail service. As of January 2025, work is expected to begin in 2026, and Amtrak service is anticipated to commence two years later, in 2028.
