Booking Strategy
For London to San Jose flights, target booking 6-8 weeks in advance for optimal pricing. September through November offers the lowest fares (€340-380), coinciding with Costa Rica’s green season when rainfall is common in the afternoon but prices drop significantly. Flying mid-week (Tuesday-Thursday) typically saves €40-80 compared to weekend departures. For the best deals, search with a 3-day flexible window and consider routing through Madrid (Iberia/BA), Paris (Air France), or Amsterdam (KLM) as these hubs offer the most competitive pricing and reasonable layover times. Avoid booking December through March during peak season unless booked 3+ months ahead. Use Skyscanner’s ‘everywhere’ search to compare routes, and consider booking separate tickets to major US hubs (United/American) if significantly cheaper, ensuring minimum 3-hour connection times for visa-free transit.
Route Tips
- Book through each airline’s official website rather than third parties to secure proper support and direct communication for any schedule changes or disruptions
- Check if your transit country (Spain, France, Netherlands) requires a visa for your nationality—these can be obtained quickly but require planning
- San Jose’s Juan Santamaría Airport (SJO) is the main hub; some flights may arrive at Liberia (LIR) in Guanacaste—check carefully which airport matches your plans
- Costa Rica requires proof of onward travel or return ticket—budget airlines sometimes deny boarding without this, so have a return ticket or a bus ticket to a neighboring country ready
- Consider the ‘Green Season’ (May-November) for lower prices—afternoon rain is typical but doesn’t ruin activities, and the landscape is remarkably lush during this period
- Monitor British Airways and Iberia prices around £295-350—these often undercut competitors on this route despite the stop in Madrid
- If traveling during rainy season (September-November), pack quick-dry clothing and waterproof layers rather than heavy rain gear
