Airport HistoryEst. 1958
Costa Rica's main international gateway opened in 1958 as 'Aeropuerto Internacional El Coco,' replacing an older airfield in downtown San José, and was later renamed for Juan Santamaría, a young drummer who died in 1856 defending Costa Rica against the American filibuster William Walker. After decades as a state-run facility, the airport moved through a turbulent private concession era in the 2000s before settling under AERIS Holdings management, and today it ranks as Central America's second-busiest airport.
The airport opened May 2, 1958, replacing an earlier downtown San José airfield; it was initially named Aeropuerto Internacional El Coco before later being renamed in honor of national hero Juan Santamaría.
A cargo aircraft crash in 1977 was among the earliest serious accidents recorded at the airport.
A five-year development plan launched in 1981 added a new runway and modern navigation aids including VOR, instrument landing systems, and radar.
SANSA Flight 32 crashed in 1990, killing 23 people, one of the deadliest accidents in the airport's history.
In May 2001 the Costa Rican government awarded Alterra Partners a 20-year private concession to manage and expand the airport, though construction was suspended in 2002 amid financing disputes, and ICAO flagged safety-regulation violations in 2005.
In July 2009 operations passed to a consortium including ADC & HAS and Andrade Gutierrez Concessões; Alterra Partners rebranded as AERIS Holdings that December, completing a facility expansion — including a ninth boarding bridge — by November 2010.
In September 2025, an electrical failure knocked out the airport's radar system, forcing a temporary suspension of all flight operations.
General encyclopedic sources (Wikipedia, CAPA, Airport Technology). The September 2025 radar outage is a recent, time-sensitive event flagged here for currency rather than as a defining historical milestone.
