Luis Munoz Marin International Airport (SJU) serves San Juan, Puerto Rico, and sits about 8 miles from the city center. The airport rests at an elevation of just 10 feet above sea level, a low-lying coastal position typical of Caribbean gateways.

The route pattern at SJU reflects strong connectivity between Puerto Rico and the mainland United States, with a particular concentration of service to the eastern seaboard and Gulf Coast regions. There is also a clear presence of shorter flights linking San Juan to other destinations within the Caribbean, underscoring the airport's dual role as both a link to the U.S. mainland and a regional hub for inter-island travel. This mix of domestic U.S. connections and Caribbean routes points to an airport of considerable scale, handling a diverse blend of longer overwater flights and shorter regional hops.

Travelers using SJU should expect a facility built around substantial traffic to and from the continental United States, complemented by a network of shorter routes serving nearby islands. The airport's low elevation and coastal setting are characteristic of its location, with no significant terrain nearby to affect operations. This combination of mainland and regional connectivity makes SJU a key access point for travel throughout the Caribbean basin.
