When this route gets cheap.
The cheapest itinerary we are tracking makes 2 stops and takes about 15 hours outbound, on a 7-night trip — ticketed under Avianca, which on a connecting fare need not operate every leg. At $902 for 10,662 km each way, that works out to about $42 per 1,000 km flown. That is about the $44 per 1,000 km typical of long-haul fares here. Across the 27 departure cities we track at a similar distance from Rio de Janeiro, this fare ranks 10th — 1.7× the $530 we hold from Houston. For context, the middle fare among the 53 routes of similar length we watch out of San Francisco is $837. We have 3 months 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 Rio de Janeiro: Apr–Jun · Sep–Oct.

The median cached fare across this calendar is 7% higher than when tracking began on 8 Aug — $843 then versus $902 now, across 10 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 $457, on 9 Dec.
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 → RIO, answered.
How far in advance should I book SF → Rio de Janeiro?
We do not publish a number for this, because we cannot measure it yet.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 Rio de Janeiro?
The current cheapest fares involve a connection, ticketed under Avianca. 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 14 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.
