When this route gets cheap.
Fares bottom out in November around $450 and peak in January near $762, 69% dearer, across the 5 months we track. The cheapest itinerary we are tracking makes one stop and takes about 4.5 hours outbound, on a 4-night trip — ticketed under Copa Airlines, which on a connecting fare need not operate every leg. At $423 for 1,808 km each way, that works out to about $117 per 1,000 km flown. That is above the $41 per 1,000 km typical of short-haul fares here. For context, the middle fare among the 8 routes of similar length we watch out of Miami is $280. The best time to be in San José: Dec–Apr.

Good to know
MIA → SJO, answered.
Is $423 a good price for Miami to San José?
Yes — the seasonal median for this route is around $545 round-trip. At $423 you're 22% below that, which we rate good for this route.
What is the cheapest month to fly from Miami to San José?
Across 5 months of cached-fare history, Nov 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 MIA → 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We do not publish a number for this, because we cannot measure it yet.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 5 months of cached fares, Nov comes out lowest on this route. Our guide Why flight prices change covers what does move a fare.
Are there nonstop flights from Miami to San José?
The current cheapest fares involve a connection, ticketed under Copa Airlines. 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 17 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.
