Luis Munoz Marin International Airport

San Juan Luis Muñoz Marín International Airport (TJSJ) sits 5 miles southeast of downtown San Juan, Puerto Rico. It is the principal commercial and business-aviation gateway to Puerto Rico and the eastern Caribbean. Commercial service is dominant (American, Delta, United, JetBlue, Southwest, Frontier, Spirit) — TJSJ is one of the busiest airports in the Caribbean — and the field handles a steady flow of US business aviation, particularly during the Caribbean winter season (December–April) and around major events. The two runways (10/28 10,400 ft, 8/26 7,400 ft) handle every current business jet without restriction. Two FBOs (Atlantic Aviation and World Aviation) handle private movements with substantial hangar capacity. Because TJSJ is a US airport (Puerto Rico is a US territory), there is no CBP / Customs requirement for arrivals from the mainland — a meaningful operational simplification versus other Caribbean destinations. Field elevation is 9 feet, no density-altitude concerns. The dominant operational considerations are hurricane season (June through November — TJSJ has been hit by major storms and brokers should brief weather contingencies), summer thunderstorms, and the standard tropical convective pattern. Ground time to Old San Juan is 15–20 minutes; Condado and Isla Verde resort districts are 5–15 minutes; the El Yunque rainforest is 45 minutes.
