LaGuardia Airport is the closest airport to Manhattan, about 8 miles away in Queens, and it handles mainly domestic flights under a federal perimeter rule that caps most nonstop routes at 1,500 miles. Built on the site of an old amusement park on Flushing Bay, it is hemmed in by water on two sides.
Right now there are 130 airports in 7 countries connected to New York, 117 of them domestic, with 39 airlines flying scheduled passenger traffic.
New York's longest nonstop connection is Las Vegas (LAS), 2,237 miles, offered by Southwest Airlines and United Airlines.
It was rebuilt from the ground up in a multi-billion-dollar redevelopment completed in the 2020s, but the 1939 Marine Air Terminal is still there: an Art Deco rotunda built for transatlantic flying boats, with the mural 'Flight' around the walls.
