Best time to be in San José: Dec–Apr. Fare history for this route is still thin, so we make no seasonal call yet.
The cheapest itinerary we are tracking makes 2 stops and takes about 15 hours outbound, on a 20-night trip — ticketed under United, which on a connecting fare need not operate every leg. At $986 for 8,317 km each way, that works out to about $59 per 1,000 km flown. That is above the $44 typical of long-haul fares here. Across the 17 departure cities we track at a similar distance from San José, this fare ranks 14th — 56% above the $631 from Madrid. For context, the middle fare among the 33 routes of similar length we watch out of Dublin is $836. We have 1 month of cached prices for this route so far — not enough to call a fare cheap or expensive, so we publish the price without a percentage.

How far in advance should I book DUB → 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We do not publish a number for this, because we cannot measure it yet.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. See /guides/what-moves-a-flight-price/ for the levers we can measure.
Are there nonstop flights from Dublin 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 August 24). 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.
