Adventure Opportunities
Beyond the city walls, adventure seekers find variety and ease. Experience the rainforest trails, cascading waterfalls, and scenic overlooks in El Yunque National Forest, where every step is rewarded.

Mix city culture with nature escapes to build a balanced, energizing itinerary.
Pro Tip: Check the official Puerto Rico tourism site for current events, seasonal festivals, and any travel advisories before you go.
Chicago to San Juan United Flights
Basic Economy Starting at $254
Basic Economy is designed for budget-minded travelers who want the lowest available fare. You typically receive a standard seat assignment at check-in and a carry-on allowance suitable for light packers. Keep in mind that there is limited flexibility for changes, and you will board in a later group. If you can travel lean and prioritize price over perks, this option can be a smart play. Monitor fare drops and be ready to book when prices dip.
$344 Seats Regular
Regular Economy balances comfort and flexibility for a smoother trip. You can choose seats in advance, which helps couples, families, and tall travelers plan their cabin setup. Priority or earlier boarding can make overhead space less stressful and the airport flow more relaxed. One checked bag allowance is often included or discounted, making it practical for longer stays. If predictability matters, this tier often justifies the extra cost.
Tip: Track prices directly on United and set fare alerts with tools like Google Flights or Skyscanner to catch limited-time deals.
Booking Your Flight
Booking smartly helps you protect both your budget and schedule. Aim to purchase tickets about two to three months before departure for better odds of a favorable fare. Be flexible with midweek departures and returns, as Tuesdays and Wednesdays can be priced lower than weekends. Log in to your MileagePlus account to earn miles and unlock upgrade or seat selection opportunities. Keep alerts active and move quickly when you spot a compelling price to avoid missing short-lived sales.

Packing for Your San Juan Trip
To avoid overpacking, pack with the climate and your activities in mind. For the beach, include swimsuits, reef-safe sunscreen, flip-flops, and a quick-dry towel. Daywear should be lightweight; think breathable shirts, shorts, and easy sundresses that transition from streets to cafés. If you plan dinners or nightlife, add comfortable evening outfits and a light layer for air-conditioned spaces. Optional snorkel gear and a reliable camera or smartphone will help you make the most of clear water and colorful streets.
Pro Tip: Keep luggage compact to reduce fees, speed up airport movement, and simplify transfers from the airport to your stay.
In-Flight Experience on United Airlines
Nonstop flights from Chicago to San Juan typically take around four to five hours, which feels quick with adequate preparation. Expect personal device entertainment or seatback access to movies, shows, and music on most mainline aircraft. Complimentary beverages are standard, and snacks or light meals may be available for purchase depending on the route. Pack headphones, a portable charger, and a light sweater for comfort across changing cabin temperatures. Small touches like a neck pillow or eye mask can upgrade even a Basic Economy ride.
Arrival in San Juan
Transportation Options
At Luis Muñoz Marín International Airport, you will find official taxis lined up curbside; confirm the fare before you depart. Rideshare services operate widely and can be convenient to major neighborhoods and hotels. If you want to explore beyond San Juan, beaches, rainforests, and coastal towns, a rental car offers the most freedom. Factor tolls and parking into your plan so costs stay predictable. For city-only trips, taxis and rideshares are often sufficient.
Cultural Etiquette
Start interactions with a friendly “Hola!” and you will notice quick smiles and helpful directions. Sampling local food, coffee, and music is more than entertainment; it is connection to community. Be patient with island time and enjoy the slower, social pace that shapes daily life. Dress casually but respectfully in religious or historic sites to show care for local traditions. A few Spanish phrases can deepen conversations and enrich your stay.
Top Places to Explore in San Juan
Old San Juan
Lose yourself along cobblestone streets filled with pastel facades and wrought-iron balconies. Visit Castillo San Felipe del Morro for sweeping Atlantic vistas and photo-worthy stone walls.

Photographers will love the diffused light and lush textures throughout the day.
Bioluminescent Bay
Evening tours reveal plankton that glow when disturbed, creating a magical ripple of light. Reserve in advance during busy seasons to secure a spot with reputable operators.
