About SJU

Luis Munoz Marin is the busiest airport in the Caribbean and the main connecting point between the mainland United States and the islands of the eastern Caribbean. It was the first major United States airport to be privatized, passing to the Aerostar consortium under a long term lease in 2013. JetBlue operates the largest share of its flights.

Luis Munoz Marin International Airport opened in 1955 at Isla Verde in Carolina, just east of San Juan. It replaced the smaller Isla Grande field near the city center. The name honors Luis Munoz Marin, the first elected governor of Puerto Rico. From the start it was the busiest airport in the Caribbean, and it has been the island's main gateway ever since.

The airport also carried the postwar wave of Puerto Ricans who moved to New York and other mainland cities. Eastern Air Lines and later American Airlines built Caribbean hubs here. A hub is an airport an airline uses to connect passengers between flights. Their schedules tied mainland arrivals to services all across the islands. American's hub peaked in the 1990s, shrank slowly, and closed for good in 2013.

That loss briefly put the airport's regional role in doubt. Low-cost airlines moved in instead, and JetBlue made San Juan a focus city, so traffic bounced back. Also in 2013, San Juan became the first large US airport privatized under a federal pilot program. The Aerostar group leased it and rebuilt terminals and shops. After Hurricane Maria in 2017, it became the lifeline for relief flights and departing residents.

How SJU operates today

San Juan has two runways. The main one, 10/28, is about 10,000 feet long, and 8/26 is shorter. Its lettered concourses have been renovated step by step under private management. No single airline dominates now. JetBlue, Frontier, Spirit, American, Delta, United, and Southwest all compete on mainland routes.

Cape Air and Silver Airways link the smaller Caribbean islands. The airport still works as a meeting point between the mainland and the region. Because Puerto Rico is US territory, mainland flights count as domestic and there is no immigration check. San Juan is also the region's main cargo base and its hurricane relief staging point.
