LaGuardia Airport is located on the waterfront in Queens overlooking Flushing Bay and Bowery Bay. It was built over the old Gala Amusement Park in 1939 and quickly became an integral part of the Northern Queens community. In 1947 LaGuardia was released to the Port Authority and it was the first airport to be “full service.” Within its walls contained a florist, beauty salon, bank, jewelry shop, and brokerage office for travelers. The airport went through several name changes before becoming what it is today. With its 680 acres of flying field and property LaGuardia is the busiest airport in the United States without non-stop service to and from Europe, handling nearly 24 million travelers in 2012. Most flights taking off from LaGuardia have destinations with the United States and Canada. Some flights, however, do travel as far as Aruba, the Bahamas and Bermuda as they are staffed with United States border preclearance facilities. LaGuardia’s has four main terminals. The Central Terminal Building sees most of the airports scheduled domestic flights and its four concourses can accommodate up to 40 aircraft gate positions. The US Airways Terminal has a 12-gate main section and an 8-gate shuttle section. The main section of the terminal features a food, retail and concessions court and a Welcome Center on the arrivals level. The Shuttle section is reserved for passengers on hourly flights to Boston and Washington, D.C. The Delta Air Lines Terminal has 10 aircraft gate positions and in July 2012 LaGuardia will serves as a Delta Air Lines hub. The Marine Air Terminal, or Terminal A, was the original airport terminal building and served international flights through the 1940. In 1995, the Marine Air Terminal was designated as a historic landmark and now houses a private weather service.
