San Juan · Puerto Rico
SJU — Luis Muñoz Marín International
A domestic flight to a Caribbean island, for US travellers at least
Puerto Rico is a United States territory, which changes the arithmetic of a Caribbean trip entirely for anyone travelling from the mainland. There is no passport requirement, no immigration queue on arrival, no customs declaration in the usual sense, and mobile phones generally work on domestic plans.
San Juan's airport is the busiest in the Caribbean and functions both as the gateway to Puerto Rico and as a connecting point for the wider region. For a traveller who wants the Caribbean without the international-travel overhead, it is difficult to beat.
Terminals and how they connect
Connected terminal concourses
The airport is arranged as a set of lettered concourses within a broadly connected structure. Moving between most of them is a walk rather than a shuttle, which makes connections here more straightforward than at many airports of comparable size.
Getting into San Juan
Times below are realistic ranges rather than best cases. Rail journeys keep to a timetable; road journeys do not, and treating the two the same is how people miss flights.
Taxi
15–25 minutes to Condado, 20–30 to Old San Juan
Fixed rates by zone from an official stand outside arrivals. The main tourist districts are genuinely close to the airport.
Ride-hailing
15–30 minutes
Available with designated pickup areas, and usually cheaper than the fixed-rate taxi.
Car rental
Immediate, then 15–30 minutes
Worth it if you intend to leave the San Juan area for El Yunque, the west coast or the south. Public transport outside the capital is limited, and a US driving licence is valid.
Connecting through SJU
San Juan is a substantial connecting point for the eastern Caribbean, with onward flights to the Virgin Islands, the Lesser Antilles and beyond. Because most mainland traffic is domestic, connections avoid the immigration step that would apply elsewhere in the region, which keeps required connection times shorter.
Worth knowing before you fly
No passport needed from the mainland US
Puerto Rico is a US territory, so travel from the fifty states is domestic. A passport is not required, though a REAL ID-compliant licence or other acceptable identification is. Travellers from other countries need whatever US entry documentation would normally apply.
The dollar and US mobile plans work here
The currency is the US dollar and most US mobile plans treat Puerto Rico as domestic. It removes a set of frictions that apply everywhere else in the Caribbean.
Hurricane season shapes the calendar
The Atlantic season runs from June to November, peaking around September. Fares are lowest then for a reason, and travel insurance is worth more in that window than at other times of year.
Terminal assignments, transit timetables and fares all change. Confirm the details that matter to your trip with the airport or transport operator before you travel.

FAQ
SJU — common questions
Terminals, transfers and getting into the city.
Do I need a passport to fly to Puerto Rico?
Not if you are travelling from the United States, because Puerto Rico is a US territory and the flight is domestic. You need acceptable identification, such as a REAL ID-compliant licence. Travellers arriving from other countries need the usual US entry documents.
Is San Juan a good place to connect in the Caribbean?
Yes. It is the busiest airport in the Caribbean with extensive onward service to the eastern islands, and connections from the US mainland avoid an immigration step because the inbound flight is domestic.
