5 Critical Travel Warnings And Alerts For SJO Airport And Costa Rica: What You MUST Know Before Flying (December 2025)

Traveling to Costa Rica? As of December 2025, travelers must be aware of several crucial security and health advisories impacting the country, especially around the primary gateway, Juan Santamaría International Airport (SJO). While the nation remains a top destination for ecotourism and "Pura Vida," the U.S. Department of State and other government bodies have issued a Level 2 Travel Advisory, urging visitors to "Exercise Increased Caution" due to crime, an alert that extends to the routes and areas immediately surrounding the airport. This article breaks down the five most critical alerts and updates you need to know to ensure a safe and smooth trip. The current advisories are not typical airport operational warnings but encompass broader security concerns, specific health requirements, and recent operational disruptions that have affected SJO and the entire Costa Rican air travel system. Being informed about these recent developments—from increased caution regarding criminal activity to new vaccination rules—is the best way to prepare for your arrival in Alajuela, where SJO is located, and your subsequent travel throughout the country.

The Current State of Costa Rica's Travel Advisory Landscape (December 2025)

Understanding the overall security posture is the first step for any traveler heading to Costa Rica. The country is currently designated with a Level 2 Travel Advisory by the U.S. Department of State. This designation is a significant entity for travelers, indicating that while travel is generally safe, visitors should be more vigilant than usual. The primary factor driving this Level 2 status is crime. The advisory specifically highlights that violent crime, such as armed robbery and homicide, is increasing, particularly in certain areas. Foreigners, including U.S. citizens, have been targets of robberies, break-ins, and ATM robberies. While SJO itself maintains high security standards, the areas and transportation routes immediately surrounding the airport are where travelers must exercise the most caution.

1. Increased Caution on SJO Airport Routes and Transportation

One of the most specific warnings for SJO travelers relates not to the terminals but to the journey to and from the airport. The U.S. Embassy in San Jose has previously recommended that travelers use caution when traveling in the area or on routes leading from the Juan Santamaría International Airport. * Targeted Crime: Criminals often target travelers who appear affluent or are distracted. Tourists are advised against displaying signs of wealth, such as expensive jewelry or electronics, and should be highly aware of their surroundings, especially when handling luggage or money. * Rental Car Risks: There have been reports of criminal incidents targeting rental cars. It is strongly recommended to use authorized, reputable taxi services (the red or orange airport taxis) or pre-arranged, established shuttle services. Avoid accepting rides from unlicensed individuals soliciting passengers outside the terminal. * LSI Keywords: *Airport transportation safety*, *Alajuela crime warning*, *rental car break-ins*.

2. The September 2025 System Outage and Operational Resilience

A major operational event occurred earlier in 2025 that travelers should note as a sign of potential, albeit rare, disruption. On September 24, 2025, both SJO and Daniel Oduber Quirós International Airport (LIR) in Liberia were temporarily closed due to a significant system outage. The issue was traced to an electrical failure that crippled the radar system at SJO, grounding flights and causing widespread delays. While the system was quickly restored, this event highlights the potential for unexpected technical disruptions. Travelers should always check their flight status before heading to the airport and be prepared for longer lines at check-in and security, as the airport has experienced technical issues that have slowed down processing times.

3. Health Alert and Enhanced Yellow Fever Vaccination Rules

Beyond security, a Health Alert was issued by the U.S. Embassy in San Jose on December 8, 2025. While the specific details of the December 2025 alert require travelers to review the full message, a key health-related requirement that began in 2025 is the enhanced yellow fever vaccination requirement. * Yellow Fever Mandate: Costa Rica's Ministry of Health has expanded the list of countries considered high-risk for yellow fever. Travelers arriving from or having transited through these designated countries must present proof of a valid yellow fever vaccination certificate upon arrival at SJO. * Required Documentation: Failure to provide the required proof of vaccination will result in denied entry. It is crucial for all travelers to check the official list of high-risk countries before departure.

4. SJO Airport Overhaul and Passenger Experience Updates

The Juan Santamaría International Airport (SJO) is undergoing an ambitious expansion and overhaul, signaling a new era for Costa Rican air travel. While the long-term goal is to improve efficiency and capacity, construction and upgrades can temporarily affect the passenger experience. * Longer Wait Times: Due to ongoing technical issues and the general increase in tourism, travelers have reported experiencing longer lines at check-in and security checkpoints. * Arrival Recommendation: It is highly recommended that departing passengers arrive at SJO at least three hours prior to their scheduled international flight departure to comfortably manage check-in, baggage drop, and security screening, especially during peak travel periods like December.

5. General Crime Prevention: A Core Part of the Travel Warning

The overarching Level 2 Travel Advisory is a constant reminder that personal security is the traveler's responsibility. The warnings about crime are not confined to the capital, San José, but apply to popular tourist areas as well. * Avoid Displaying Wealth: Do not wear expensive jewelry or watches. Keep cell phones and cameras concealed when not in use. * Secure Documents: Use hotel safes for passports, extra cash, and other valuables. Carry only copies of your passport and necessary daily cash. * Accommodation Security: Be cautious of rental property break-ins. Ensure your accommodations have secure locks and do not leave valuables visible. * LSI Keywords: *Personal security tips*, *Costa Rica travel safety*, *robbery prevention*, *tourist scams*. In summary, the current travel warning for the SJO airport area is a multifaceted advisory covering general crime, specific health requirements, and operational readiness. By adhering to the Level 2 "Exercise Increased Caution" guideline, planning for potential airport delays, and following the new health protocols, you can navigate your journey through SJO safely and enjoy the natural beauty and hospitality of Costa Rica.
