Question : What day in the next four weeks has the best fares?
Answer : Since low prices are preferred, look at Apr 13th. As of Mar 20th, it's showing the cheapest ticket sales at $527. That is 19% below the average price for this route, so you can spend that extra money on an adventure rather than the flight.
Question : Is the price you found a good deal?
Answer : Ranging from $527 to $932, prices for GRB to SJO fluctuate less than the majority of routes from the United States. The further out you book a route, the more likely you are to save.

Question : How long do most people stay in San Jose?
Answer : Of course you're not most people, but if you were, you'd stay roughly nine days.
Question : Would you be willing to change your travel days if it saved you money?
