When this route gets cheap.
Fares bottom out in November around $1,511 and peak in February near $1,778, 18% dearer, across the 4 months we track. The cheapest itinerary we are tracking makes 2 stops and takes about 27.5 hours outbound, on a 19-night trip — ticketed under American, which on a connecting fare need not operate every leg. At $1,511 for 11,347 km each way, that works out to about $67 per 1,000 km flown. That is above the $42 per 1,000 km typical of ultra-long-haul fares here. Across the 25 departure cities we track at a similar distance from Santiago, this fare ranks 25th — 2.8× the $534 we hold from Toronto. For context, the middle fare among the 24 routes of similar length we watch out of Sydney is $1,368. The best time to be in Santiago: Oct–Apr.

Good to know
SYD → SCL, answered.
Is $1,511 a good price for Sydney to Santiago?
Only slightly. The seasonal median is around $1,565 round-trip and this fare is 3% under it. We do not call a drop notable until 20%, so this is an ordinary price for the route rather than a reason to hurry.
What is the cheapest month to fly from Sydney to Santiago?
Across 4 months of cached-fare history, Nov comes out cheapest on this route. The best months to actually be in Santiago are Oct–Apr — when those overlap, that's your window.
How far in advance should I book SYD → Santiago?
We do not publish a number for this, because we cannot measure it yet.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 4 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 Sydney to Santiago?
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 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.
