When this route gets cheap.
The cheapest itinerary we are tracking makes 2 stops and takes about 22 hours outbound, on a 21-night trip — ticketed under American, which on a connecting fare need not operate every leg. At $1,432 for 13,808 km each way, that works out to about $52 per 1,000 km flown. That is above the $42 per 1,000 km typical of ultra-long-haul fares here. Across the 11 departure cities we track at a similar distance from San José, this fare ranks 4th — 1.7× the $865 we hold from Istanbul. For context, the middle fare among the 42 routes of similar length we watch out of Sydney is $1,319. 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. Fare history here is still too short to name a cheap season. The best time to be in San José: Dec–Apr.
We are still collecting this route's months — 1 month of cached prices so far, too few to chart.

Good to know
SYD → SJO, answered.
How far in advance should I book SYD → 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We do not publish a number for this, because we cannot measure it yet.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. Our guide Why flight prices change covers the levers we can measure.
Are there nonstop flights from Sydney to San José?
The current cheapest fares involve a connection, ticketed under American. We hold no nonstop fare on this route right now, which does not mean none flies — search your exact dates to see what does.
Are these prices guaranteed?
No — these are cached fares found on real searches (this one on 10 October). 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.
