LaGuardia, the smallest of New York's primary airports, handles domestic flights. It is named for Fiorello H. LaGuardia, the city's great Depression-era mayor known as a reformist and strong supporter of the New Deal. A perimeter rule prohibits incoming and outgoing flights that exceed 1,500 miles (2,400 km) except on Saturdays, when the ban is lifted, and to Denver, which has a grandfathered exemption. As a result, most transcontinental and international flights use JFK and Newark. The airport is located in northern Queens about from downtown Manhattan. Plans were announced in July 2015 to entirely rebuild LaGuardia Airport in a multibillion-dollar project to replace its aging facilities.
