When this route gets cheap.
The cheapest itinerary we are tracking makes one stop and takes about 14.5 hours outbound, on a 6-night trip — ticketed under Copa Airlines, which on a connecting fare need not operate every leg. At $1,691 for 10,416 km each way, that works out to about $81 per 1,000 km flown. That is above the $44 per 1,000 km typical of long-haul fares here. Across the 30 departure cities we track at a similar distance from Buenos Aires, this fare ranks 29th — 3.1× the $550 we hold from New York. For context, the middle fare among the 51 routes of similar length we watch out of San Francisco is $835. 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 Buenos Aires: Oct–Dec · Mar–May.

The median cached fare across this calendar is 2% lower than when tracking began on 8 Aug — $1,078 then versus $1,053 now, across 12 recorded snapshots. This is a calendar-level trend, so an individual deal above can be lower. The lowest single day we have seen here is $963, on 7 Sep.
These are the only days we have a cached price for on this route so far — not the only days it flies. The search above covers any date.

Good to know
SF → EZE, answered.
How far in advance should I book SF → Buenos Aires?
We do not publish a number for this, because we cannot measure it yet.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 San Francisco to Buenos Aires?
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.
