As the major gateway to Puerto Rico, it offers an extensive network of non-stop arrivals from destinations across the United States, Latin America, the Caribbean, and Europe, supported by intense airline competition into SJU.

The airport features a dense schedule of highly competitive arrival routes from major U.S. cities. Top departure points include New York (JFK, EWR, LGA), Miami (MIA), Fort Lauderdale (FLL), Orlando (MCO), Boston (BOS), and Atlanta (ATL) into SJU. Key international arrival connections include direct flights from Panama City, Santo Domingo, Madrid, and Toronto into San Juan, along with numerous Caribbean islands.

SJU is a critical focus city and competitive battleground for multiple airlines flying into San Juan. Major U.S. carriers like JetBlue, American Airlines, Delta, and United operate extensive routes to SJU. Low-cost carriers Spirit Airlines and Frontier Airlines have a strong presence into San Juan, driving down fares on many U.S. mainland arrival routes. Cape Air provides essential connectivity within the Caribbean and from other Puerto Rican airports into SJU.

To secure the cheapest flights to San Juan, book U.S. mainland arrival routes 1-2 months in advance into SJU and international arrivals 2-4 months ahead.
