Situated in the borough of Queens, LaGuardia Airport is a major hub for domestic flights in and out of New York. Good ground transport connections make this a convenient arrival point for visitors landing in New York from destinations all across the United States.

The airport handles a huge proportion of New York's domestic air traffic but has no border control, so the only international flights are those from airports with United States border pre-clearance in Canada. Close to 30 million passengers use LaGuardia Airport each year.Most airlines use Terminal B, where the airport's main shopping and restaurant space is located. The major exceptions are Delta Airlines and Delta Connection who use Terminals C and D. Delta Shuttle is the only airline operating out of the original Terminal A. A free bus service connects the terminals.

LaGuardia Airport is not on the New York subway line, but local buses link the airport to the two nearest stations. These buses are free for anyone with a New York MetroCard. Direct buses connect the airport with Manhattan and Long Island. Metered taxis are readily available outside the arrivals gates, and taxi dispatchers assist passengers within the terminals.

LaGuardia Airport was originally a hub for flying boats, the long-distance seaplanes that hopped across the world in the 1930s and could use both water and land runways.
