When this route gets cheap.
Fares bottom out in February around $1,925 and peak in December near $2,315, 20% dearer, across the 4 months we track. The cheapest itinerary we are tracking makes 2 stops and takes about 31 hours outbound, on a 11-night trip — ticketed under Air France, which on a connecting fare need not operate every leg. At $1,925 for 19,433 km each way, that works out to about $50 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 Buenos Aires, this fare ranks 8th — 52% above the $1,264 from Delhi. The best time to be in Buenos Aires: Oct–Dec · Mar–May.

Good to know
SEL → EZE, answered.
Is $1,925 a good price for Seoul to Buenos Aires?
Only slightly. The seasonal median is around $2,170 round-trip and this fare is 11% 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 Seoul to Buenos Aires?
Across 4 months of cached-fare history, Feb comes out cheapest on this route. The best months to actually be in Buenos Aires are Oct–Dec · Mar–May — when those overlap, that's your window.
How far in advance should I book SEL → 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We do not publish a number for this, because we cannot measure it yet.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. What we can measure is which month is cheap: across 4 months of cached fares, Feb comes out lowest on this route. Our guide Why flight prices change covers what does move a fare.
Are there nonstop flights from Seoul to Buenos Aires?
The current cheapest fares involve a connection, ticketed under Air France. 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.
