Travelers have found it’s best to book a flight 44 days in advance to save up to 20% compared to booking the same week of travel. As your travel date approaches, the cost of this flight route may potentially increase. While opting to book 44 days out may not be an option for all, there are still additional ways to secure a deal in the near future. You might find a flight from Costa Rica to San Francisco 1-2 weeks in advance for as low as $117, or $137 for flights within the next 24 hours.
Our data shows that February tends to be the cheapest month to fly to San Francisco from Costa Rica. Users have commonly found prices around $121 for the month, but tickets can be as low as $61. Due to multiple factors, prepare for potentially higher prices in April.
