Puerto Rico

Puerto Rico is an unincorporated US territory in the Caribbean, making it a unique travel destination that combines tropical island appeal with the convenience of domestic US travel. Located between the Dominican Republic and the US Virgin Islands, the island attracts millions of visitors annually with its historic Old San Juan, pristine beaches, bioluminescent bays, and the only tropical rainforest in the US National Forest System.

For US citizens, Puerto Rico offers significant advantages: no passport required, no customs or immigration, ability to use US dollars and mobile plans, and domestic flight rules apply. The main gateway is Luis Munoz Marin International Airport (SJU) in San Juan, which handles the vast majority of international and mainland US traffic. Smaller airports at Aguadilla (BQN) and Ponce (PSE) provide alternative access to the western and southern regions.

Puerto Rico serves as a JetBlue focus city, with extensive service from the carrier alongside all major US airlines. The island's location makes it an ideal jumping-off point for exploring the wider Caribbean.

Primary Airports

San Juan (SJU) — Luis Munoz Marin International Airport is Puerto Rico's main gateway and one of the busiest airports in the Caribbean. Located 10 miles east of San Juan in the Carolina district, it handles approximately 10 million passengers annually. The airport serves as a JetBlue focus city with extensive service to the US mainland, particularly the East Coast. Two terminals handle domestic US and international flights, with connections to destinations throughout the Caribbean, Latin America, and Europe.

Aguadilla (BQN) — Rafael Hernandez Airport serves the western coast of Puerto Rico, convenient for visitors heading to Rincon (surfing), Cabo Rojo, and the western beaches. Located on the site of a former US Air Force base, it has seen growth from low-cost carriers including JetBlue, Spirit, and Frontier, offering an alternative to the larger San Juan airport.

Ponce (PSE) — Mercedita Airport serves Puerto Rico's second-largest city on the southern coast. Limited commercial service (primarily JetBlue to JFK and Orlando) makes it useful for travelers focused on the southern region, including the Ponce historic district and nearby beaches.
