The airport's history

The airport code for San Juan Airport is SJU for IATA and ICAO codes, and TJSJ for the ICAO code. The airport is named Luis Muñoz Marín International Airport and is located in San Juan, Puerto Rico. It is the island's main point of entry and the busiest airport in the Caribbean.

History

San Juan Airport has been operational since 1929, when the Isla Grande Airport served as Puerto Rico's main airport. However, by 1945, the Puerto Rican government recognised the need for a new international airport to accommodate the growing air traffic. The Isla Grande Airport's 4,000-foot (1,200-metre) airstrip was insufficient for modern aircraft, prompting the government to initiate the project for a new airport in 1947.

Luis Muñoz Marín International Airport was inaugurated in 1955 and has since undergone gradual expansion. The airport has faced challenges, including competition from low-cost carriers and financial crises, leading to upgrades and improvements in 2012 and 2013. The airport is now managed by Aerostar Airport Holdings under a private-public initiative.

Over the years, the airport has been served by a variety of airlines, including major international carriers such as Lufthansa, Air France, British Airways, and Virgin Atlantic. It currently serves as a hub for Heritage Airlines and JetBlue Airways, with JetBlue being the largest carrier in San Juan.

Luis Muñoz Marín International Airport is accessible from the San Juan district of Hato Rey via the Teodoro Moscoso Bridge. It has one main terminal building with four concourses and a separate terminal, all of which are interconnected. The airport has four designated terminals: A, B, C, and D, offering domestic and international flights to various destinations.
