What to Know Before Booking Flights to Costa Rica (2026)

Planning your dream trip to Costa Rica? Before you hit “book,” let’s talk about the real secrets to finding the best flights.

After years of flying in and out of Costa Rica from the U.S. and Europe, we’ve learned what actually matters when booking: which airport to choose, when to buy, and how to avoid costly mistakes (like booking the wrong “San Jose”).

In this guide, you’ll find everything we’ve learned, from our favorite flight search tools and smart travel insurance tips to the best time of year to find deals.

The Two International Airports in Costa Rica

Costa Rica has two international airports. Choosing the right one can save you hours of driving time once you land.

The main thing to know is…

• San José (SJO) is ideal for central, southern, and Caribbean adventures
• Liberia (LIR) is best for northern and Pacific beach getaways.

Let’s break down each one.

Juan Santamaría International Airport (SJO – San José)

Located in Alajuela (just outside San José) this is Costa Rica’s busiest airport and your best gateway to most of the country.

Fly into SJO if you plan to visit:

• La Fortuna / Arenal Volcano Region
• Monteverde Cloud Forest
• Manuel Antonio & the Central Pacific Coast
• The Osa Peninsula (Sierpe or Puerto Jiménez via domestic flight)
• The Caribbean Coast (Limón, Puerto Viejo de Talamanca)

Good to know:

• It’s about a 30-minute drive from downtown San José but expect heavy traffic at peak hours. It can sometimes take over an hour to get downtown.
• The airport is compact and efficient, but immigration lines can be long at times
• You’ll find a full-service Adobe Rent a Car office five minutes away for easy pickup.

Daniel Oduber Quirós International Airport (LIR – Liberia)

If your dream trip involves beaches, surf towns, or resorts in Guanacaste, this airport will save you serious road time.

Fly into LIR if you plan to visit:

• Tamarindo & Playa Grande
• Nosara & Samara
• Playa Hermosa, Playa Panama & Papagayo Peninsula
• Rincón de la Vieja National Park
• Monteverde & La Fortuna (combine with a short drive)

Good to know:

• Located about 15 minutes outside Liberia City.
• Immigration is typically quick, and baggage claim is easy to navigate.
• Perfect for short trips focused on the north or Pacific Coast.

Airlines That Fly to Costa Rica

The great news is that it has never been easier to find a flight to Costa Rica. Both San José (SJO) and Liberia (LIR) now welcome nonstop routes from across the U.S., Canada, and Europe.

Below, we’ve broken it down so you can easily find your best route.

From the United States & Canada

Most major North American airlines have routes into San José (SJO) and/or Liberia (LIR).

Airlines:

• American Airlines
• United Airlines
• Delta Air Lines
• JetBlue
• Southwest Airlines
• Alaska Airlines
• Spirit Airlines
• Air Canada / Air Transat
• Frontier Airlines

Thing to Keep in Mind

When flying back home from Costa Rica you need to go through border control once you enter the U.S. If you have a connecting flight you will need to pick up your checked luggage, drop it off again, and then go through security again.

Keep this in mind when looking at how much time you have as a stopover. If you will need to do this I suggest giving yourself 1.5 hours for your stopover. 

From Europe

Europeans now have more nonstop routes than ever before.

Direct Routes

• Lufthansa — Frankfurt ↔ San José
• KLM Royal Dutch Airlines — Amsterdam ↔ San José & Liberia
• Iberia Airlines — Madrid ↔ San José
• British Airways — London Gatwick ↔ San José
• Edelweiss Air (Swiss) — Zürich ↔ San José
• Air France — Paris ↔ San José

Things to Keep in Mind

• If you are an EU citizen and book a flight with a stopover in the US you will need a ESTA for entry.
• Also, if you book through the US make sure you allow yourself a ton of time between flights. Going through border control in the US as a foreigner can take foreverrrrr. Last time, I, as a US citizen, got through in 20 minutes. It took Thomas (a German citizen) over an hour.

From Latin America & the Caribbean

If you’re traveling from within the region, Costa Rica is a hub for several airlines.

Airlines & Routes

• Aeroméxico — Mexico City ↔ San José
• Volaris / Volaris Costa Rica — Routes to Miami, Orlando, Cancun, Tulum, Mexico City, San Salvador, and Guatemala City
• Avianca / Avianca Costa Rica — Extensive connections from Bogotá, Medellín, Quito, Lima, and beyond
• Copa Airlines — Daily flights via Panama City (Tocumen)

Our Favorite Flight Booking Site

After years of flying between Costa Rica, the U.S., and Europe, we’ve tested every booking site out there, but we always come back to Skyscanner.

It consistently finds the best prices, even on smaller airlines that don’t always show up elsewhere.

Why We Love Skyscanner

• Flexible Date Search – See which days are cheapest with the “Whole Month” calendar view.
• Multi-City Option – Fly into one airport (San José) and out of another (Liberia) to save on long return drives.
• Regional Pricing Trick – Change your “Country” setting to see fares listed on foreign booking sites. Sometimes that alone can save you $100+.
• Price Alerts – Turn on email alerts so Skyscanner messages you the moment fares drop.

Pro Tip: You might want to consider flying into San José (SJO) and out of Liberia (LIR) for a one-way road trip across the country.

When Is the Cheapest Time to Fly to Costa Rica?

If your travel dates are flexible, timing your trip right can make a big difference.

Here’s a breakdown of when flight prices usually drop and what to expect once you land.

September to Early December – Best Value Season

This is Costa Rica’s green season. That means afternoon rains, lush jungles, and fewer crowds.
It’s also when airlines lower fares to fill planes.

• Expect: The best prices on flights (and hotels), especially in September, October, and early December.
• Weather: Mornings are often sunny, but pack a light rain jacket for tropical afternoon showers.
• Tip: Great time to visit the Caribbean coast, which actually has some of its sunniest weather this time of year.

January to April – High Season, High Prices

This is Costa Rica’s dry season, the most popular (and expensive) time to visit.

• Expect: Higher flight prices, especially around Christmas, New Year’s, and Easter.
• Weather: Blue skies and warm sunshine nearly every day on the Pacific coast.
• Tip: Book 3–4 months in advance for the best fares.

May to August – Shoulder Season Sweet Spot

This is the secret “best of both worlds” time.

The landscapes are lush, wildlife is active, and prices haven’t hit their summer or holiday peak.

• Expect: Moderate prices and frequent airline deals.
• Weather: Occasional rain, but plenty of sunshine too, especially on the northwest coast.
• Tip: Great time to combine La Fortuna + Guanacaste for a balanced mix of adventure and beach.

Tips for Finding Cheap Flights to Costa Rica

Finding a great deal is all about timing, flexibility, and a few insider tricks. Here’s what we’ve learned from years of flying in and out of Costa Rica.

Book Mid-Week for the Best Fares

Flight prices fluctuate constantly, but mid-week bookings (especially Tuesday and Wednesday) often come out cheapest.
That’s when airlines roll out new sales or adjust unsold seat prices from the weekend.

Pro Tip: Use Skyscanner’s “Whole Month” view to spot the lowest fare days. It’s one of our favorite features.

Travel During the “Green Season”

If you’re flexible, fly between September and early December for the best value.

This is Costa Rica’s rainy season, which means fewer crowds, lush scenery, and lower airfares.

Bonus: The Caribbean side (Puerto Viejo, Cahuita, Manzanillo) is actually at its sunniest during these months!

Set Up Flight Alerts

Never overpay again. Just set an alert and wait.

Sites like Skyscanner let you track your preferred route and email you when prices drop.

Travel Tip: Start tracking flights about four to five months before travel. It’s usually the sweet spot for the lowest fares.

Compare San José vs. Liberia

A decade ago, flying into San José (SJO) was always cheaper. That’s no longer the case.
Liberia (LIR) often has competitive or even lower fares.

Join Rewards & Travel Points Programs

If you travel often, airline and credit card reward programs can really pay off.
Most airlines flying to Costa Rica (Delta, United, JetBlue, American) have mileage programs that add up fast.

💡 Credit Card Tip: The Chase Sapphire Reserve is a favorite among frequent travelers for its travel insurance, airport lounge access, and flexible point redemptions. It’s awesome!

🪶 Pro Tip: Use one card consistently for flights, hotels, and car rentals to rack up free trips faster.

Things to Know Before You Fly to Costa Rica

Before you head to the airport, there are a few key things that will make your travel day smoother (and possibly save you money and stress once you land).

Double-Check the Airport Code

You’d be amazed how often people accidentally book flights to San Jose, California (SJC) instead of San José, Costa Rica (SJO).

Always confirm your ticket says:

San José, Costa Rica – SJO or Liberia, Costa Rica – LIR

Pack Smart

Keep one change of clothes, medications, and essentials in your carry-on.

Lost luggage isn’t common, but they happen (especially if you’re connecting through the U.S. or Europe).

If your bag does get lost or your flight delayed, AirHelp can often claim compensation on your behalf.

Entry & Border Control Tips

When you land, you’ll go through Costa Rican immigration before collecting your luggage.
You’ll need to show:

• Your passport (valid at least 6 months)
• Proof of onward travel (a flight or bus ticket out within 90 days)

Travel Tip: Keep your accommodation name and address handy. The border agent might ask for it.
