SJU San Juan Airport Guide

My first trip to Puerto Rico started with stepping off the jet bridge at SJU and getting hit by that warm, humid air. I knew right then the trip was going to be good. Luis Munoz Marin International Airport — SJU on your boarding pass — is the main way in and out of Puerto Rico, and it’s the busiest airport in the Caribbean. So yeah, it’s kind of a big deal.

Terminal Layout

SJU has two terminal buildings, Terminal A and Terminal B. Terminal A mostly handles international flights and has gates built to accommodate larger planes. Terminal B takes care of most domestic routes along with some international service. The whole layout is fairly straightforward. Signage is in both Spanish and English, which helps a lot when you’re trying to find your gate after a long flight.

Navigating SJU has gotten complicated with all the construction and updates flying around in recent years, but honestly, compared to some stateside airports I’ve been through, it’s manageable. Just follow the signs and you’ll be fine.

Check-In and Security

Both terminals have multiple check-in counters. The standard advice applies: get there two hours early for domestic, three for international. I’ve found that to be pretty accurate, especially during peak season when half of the East Coast seems to be heading to the island. TSA PreCheck and Global Entry work here, which speeds things up if you’re enrolled. I signed up for Global Entry a couple years ago and it’s saved me more stress than I can quantify.

Getting Around Once You Land

Probably should have led with this, because figuring out transportation is the first real decision you make after landing. Here’s what’s available.

Car rentals are right there at the airport. Hertz, Avis, Enterprise, and others all operate on-site. The rental center is walking distance from the terminals, which is nice — no shuttle bus required. I’d recommend reserving ahead of time though. During busy weeks, cars go fast.

Taxis line up outside the arrivals area. They’re easy to grab and most drivers know the island well. If you prefer ride-sharing, Uber and Lyft both operate in Puerto Rico. Pricing tends to be competitive, sometimes cheaper than a cab depending on demand.

Public buses exist too, and they’re the budget-friendly option. Several routes connect SJU to different parts of San Juan and surrounding areas. They’re not the fastest way to get around, but if you’re not in a rush and want to save money, they work.

Food and Shopping

The food options at SJU are better than average for an airport, in my experience. Margaritaville is there if you want to start your vacation early with a frozen drink and some decent bar food. El Meson is a local chain that serves solid Puerto Rican fare — their breakfast sandwiches are actually really good. I’ve made a habit of grabbing one on my way out every time.

Shopping covers the usual airport spread. Duty-free stores, local craft shops, and travel essentials. I always end up buying something I don’t need. Last time it was a bottle of Don Q rum and a hat I’ve worn exactly once. No regrets though.

Free Wi-Fi is available throughout the airport, which keeps you connected while you wait. That’s what makes SJU endearing — for a Caribbean airport, it has the amenities you’d expect from a mainland hub.

Lounges

If you want a quieter spot to wait, several lounges offer premium services. You can get in through airline status, lounge memberships, or by purchasing a day pass. The lounges have comfortable seating, food, drinks, and a generally calmer atmosphere than the main terminal. Worth it for long layovers, in my opinion.

Hotels Near the Airport

If you’ve got a super early flight or a long layover, there are solid hotel options nearby. The San Juan Airport Hotel is literally inside the airport — about as convenient as it gets. Courtyard by Marriott is close by with free airport shuttle service, and they’ve got decent rooms. Hampton Inn and Suites is another reliable option with shuttle service, just a short drive away.

I stayed at the Courtyard once when I had a 6 AM flight and it was painless. Shuttle picked me up, I was at my gate in 20 minutes. Sometimes spending the money on an airport hotel is the smartest play.

Tips from Someone Who’s Been There

Download the airport’s official app if you can. It gives you real-time flight updates, terminal maps, and info on services and food. I didn’t know about it my first trip and spent way too long wandering around looking for a coffee shop.

Bring a refillable water bottle. There are drinking fountains around and you’ll want to stay hydrated, especially with the Puerto Rico heat waiting for you outside. Keep your passport and boarding pass somewhere easy to reach — digging through your bag at every checkpoint gets old fast.

And check for travel advisories before you go. Weather events and other situations can affect flight schedules, and it’s better to know ahead of time than to find out at the gate. I learned that lesson during a near-miss with a tropical storm in 2019. We made it out, but just barely, and I’ve been more careful about checking conditions ever since.
