San Juan Airport (SJU)

Luis Muñoz Marín International Airport (SJU) operates one main terminal building divided into four concourses: Terminal A, Terminal B, Terminal C, and Terminal D. Together they offer around 40 gates: Concourse A (gates A1–A8) is used primarily by JetBlue and regional carriers, Concourse B (gates B2–B10) hosts the main ticketing counters shared by all concourses, Concourse C (gates C2–C10) handles most international departures, and Concourse D (gates D1–D9) serves smaller regional operators. All four concourses are connected beyond security, so passengers do not need to exit and re-enter the building to reach any gate.

No, since Puerto Rico is a U.S. territory, flights between the U.S. mainland and SJU are considered domestic travel. Here is what you need to know:

• S. citizens and permanent residents flying directly from the U.S. mainland need only a valid, TSA-accepted photo ID, such as a REAL ID-compliant driver's license or a U.S. passport.
• There is no customs declaration, immigration checkpoint, or entry form required for U.S. citizens arriving from the mainland; it works exactly like flying between any two U.S. cities.
• International visitors arriving directly into SJU from outside the United States clear standard U.S. Customs and Border Protection (CBP), and non-U.S. citizens must present a valid passport along with an approved ESTA or U.S. visa, as applicable.
• On departure to the U.S. mainland, all checked and carry-on bags pass through a routine USDA agricultural inspection to screen for plants and produce; no ID is required for this step.

Luis Muñoz Marín International Airport (SJU) is the busiest airport in the Caribbean and can experience high volumes during peak periods. To ensure a smooth departure, we recommend the following:

• Domestic flights (to/from the U.S. mainland): Arrive at least 2 hours before your scheduled departure.
• International flights: Arrive at least 3 hours before your scheduled departure. 

These times allow for check-in, baggage drop, security screening, and walking to your gate, which can take 15 to 20 minutes between the farthest concourses. Arriving early is especially advised during holiday seasons, spring break, and long weekends.

Yes, you can rent a car at San Juan Airport. Luis Muñoz Marín International Airport has a rental car facility located on the first floor, directly across from baggage claim, with around a dozen international and local agencies to choose from.

When packing for Puerto Rico, the following personal items are generally permitted under standard TSA domestic rules:

• Sealed packaged food items for personal use
• Medications (carry prescriptions or documentation for any controlled substances)
• Clothing, personal care items, and accessories

All passengers departing Luis Muñoz Marín Airport for the U.S. mainland pass through a routine USDA (APHIS) agricultural inspection designed to prevent the spread of plant pests and diseases. Fresh fruits, plants, and certain agricultural products may be restricted or require inspection before you're cleared to board.

Always check current guidelines before packing food or plant items for your return trip. For authoritative and current regulations, consult the official website of the USDA Animal and Plant Health Inspection Service (aphis.usda.gov).

Ensure a smooth trip by having your documents prepared:

• A TSA-accepted photo ID (REAL ID-compliant license or U.S. passport) for domestic flights; a valid passport for international travel.
• No customs declaration is required for U.S. citizens arriving from the mainland.
• Non-U.S. citizens arriving internationally should carry a valid passport and, if applicable, an approved ESTA or U.S. visa.
