All Carriers at SJU
Who Flies to San Juan
SJU is the Caribbean's busiest airport -- served by every major U.S. carrier plus regional inter-island airlines and international routes.
American has the largest presence at SJU of any carrier, treating it as a focus city with dozens of daily departures. If you are connecting from a smaller U.S. city, American through MIA or CLT is often the most direct routing. Admirals Club available airside at SJU.
JetBlue is the second-largest carrier at SJU and a favorite for travelers from the Northeast. Their Mint business class product operates on select SJU routes. Known for good legroom, free Wi-Fi, and competitive fares. JetBlue frequently has the best prices on the JFK--SJU corridor.
Delta connects SJU to their Atlanta mega-hub -- the largest in the world -- opening up hundreds of connecting cities. Good option for travelers from the Southeast and Midwest. Delta One and Comfort+ available on select SJU routes.
United serves SJU from their Newark hub -- good for New York/New Jersey travelers who prefer EWR over JFK -- and from Chicago and Houston. United Polaris business class available on select routes.
Southwest brings its no-frills, bags-fly-free model to SJU. Good value for leisure travelers, especially from Florida, Baltimore, and other Southwest strongholds. No assigned seating -- check in early for best boarding position.
Spirit offers the lowest base fares to SJU from Florida gateways. Fees for bags, seat selection, and snacks add up -- calculate the total cost before booking. Best for carry-on-only travelers on a tight budget.
Cape Air is the essential inter-island carrier connecting SJU to the USVI and BVI. Multiple daily flights to STX, STT, and EIS on 9-seat Cessna 402 turboprops. 25-lb baggage limit applies. Interline agreements with American and JetBlue allow through-ticketing from the mainland. Departs from the regional terminal at SJU.
Silver Airways offers larger-capacity turboprop service on Caribbean inter-island routes and connects SJU to Fort Lauderdale. The ATR aircraft provide more cabin space and baggage allowance than Cape Air. Good alternative when Cape Air is full or for travelers with more luggage.
Copa connects SJU to their Panama City hub, opening up connections to 80+ destinations across Latin America and the Caribbean. Best option for travelers heading to Central America, South America, or other Caribbean islands not served by U.S. carriers.
