Cached-fare history: across 4 months, Jan is the cheapest for FRA → SJO. Best time to be there: Dec–Apr.
Fares on this route stay within about $64 across the 4 months we track — season matters less here than timing the drop. The cheapest itinerary we are tracking makes one stop and takes about 18 hours outbound, on a 16-night trip — ticketed under United, which on a connecting fare need not operate every leg. At $882 for 9,351 km each way, that works out to about $47 per 1,000 km flown. That is about the $44 typical of long-haul fares here. Across the 19 departure cities we track at a similar distance from San José, this fare ranks 7th — 40% above the $631 from Madrid. For context, the middle fare among the 37 routes of similar length we watch out of Frankfurt is $730.

FRA → SJO, answered.
Is $882 a good price for Frankfurt to San José?
Only slightly. The seasonal median is around $920 round-trip and this fare is 4% under it, about $38. We do not call a drop notable until 20%, so this is an ordinary price for the route rather than a reason to hurry.
What is the cheapest month to fly from Frankfurt to San José?
Across 4 months of cached-fare history, Jan comes out cheapest on this route. The best months to actually be in San José are Dec–Apr — when those overlap, that's your window.
How far in advance should I book FRA → San José?
We do not publish a number for this, because we cannot measure it yet. Answering it honestly means watching the same departure date on this route over many weeks as it approaches, and that archive is still filling up — so any "book N days ahead" figure here would be borrowed from somewhere else rather than measured. What we can measure is which month is cheap: across 4 months of cached fares, Jan comes out lowest on this route. See /guides/what-moves-a-flight-price/ for what does move a fare.
Are there nonstop flights from Frankfurt to San José?
The current cheapest fares involve a connection, ticketed under United. Nonstop options exist on many dates at higher prices — check the live search for your exact dates.
Are these prices guaranteed?
No — these are cached fares found on real searches (this one on September 1). Airlines reprice constantly, so the booking search re-checks the live price before you pay. Fresher finds are far more likely to still be available.
