✈️ Flight Guide: Charleston (CHS) → San Jose (SJO)

January in Costa Rica features a range of cultural and tourism events due to the dry season and holiday spillover. Notable occurrences include the Palmares Festival (typically held in late January in Palmares, Alajuela province) and smaller local fairs, artisan markets, and beach festivals along the Pacific coast near Manuel Antonio and Tamarindo. These events boost demand for accommodations and transfers, so book early when traveling from Charleston International Airport (CHS) to Juan Santamaría International Airport (SJO). Use search terms like "Palmares festival January" or "San José January events" to align trip planning with local festivities.

The best time to fly from Charleston International Airport (CHS) to Juan Santamaría International Airport (SJO) depends on your priorities: for the best weather, December through April (including January) is ideal because it’s Costa Rica’s dry season. For lower prices and fewer crowds, consider shoulder months like May or September. If you must travel in January, book as early as possible—60–90 days out—to lock in reasonable fares and secure desired flight times. Use search terms like "best time to fly to San José" and "cheap CHS to SJO January" to compare options and timing.

On the CHS–SJO route, direct flights are rare and often more expensive, while one-stop connections through major hubs provide more schedule flexibility and often cheaper fares. Connecting flights can add total travel time but may substantially reduce price; however, they carry higher risk of missed connections and baggage delays, especially during January’s busy period. If you value convenience and minimal transit time, prioritize shorter layovers on same-airline itineraries; if saving money is the goal, allow for longer connections and check multi-airline solutions. Use search phrases like "best nonstop CHS SJO" or "cheap connecting flights Charleston to San José" when comparing options.

Common carriers for CHS to SJO itineraries include legacy U.S. airlines and their regional partners, with connections through Atlanta (Delta), Charlotte (American), and Miami (American or other partners). Delta often offers convenient connections via Atlanta with extensive onward service to SJO, while American Airlines provides frequent schedules through Miami or Charlotte. Consider baggage fees, seat selection costs, and loyalty program status when comparing fares for January travel. Search using keywords like "Delta CHS to SJO" or "American Airlines Charleston to San José" to compare schedules, prices, and onboard amenities; booking directly with the carrier can simplify changes during busy January travel periods.

January is prime time to visit Costa Rica, so expect sunny weather on the Pacific slope and busy tourist corridors. Pack lightweight layers, sturdy walking shoes for cloud-forest hikes, reef-safe sunscreen for beach outings, and a small waterproof layer for occasional mountain showers.

For best value, search for "January Costa Rica travel deals" and set fare alerts from Charleston International Airport (CHS) while confirming flexible ticket terms and travel insurance before departure.
