One of three major airports in the New York metropolitan area, New York LaGuardia Airport (LGA) is located in the borough of Queens about seven miles from Midtown Manhattan. The airport, which has four terminals, two runways and two helipads, handled almost 27 million passengers in 2014. About 10 airlines fly to and from LaGuardia, including Delta Air Lines, which uses it as a hub, and American Airlines, which has designated it as a focus city. By law, flights to and from LaGuardia must be no more than 1500 miles. Longer flights are allowed on Saturdays, and flights to Denver are also permitted. Because there is no customs or immigration service at LGA, the only international flights are from Canadian airports with pre-clearance facilities.
