When this route gets cheap.
Fares bottom out in November around $899 and peak in December near $1,495, 66% dearer, across the 4 months we track. The cheapest itinerary we are tracking makes one stop and takes about 13 hours outbound, on a 6-night trip — ticketed under United, which on a connecting fare need not operate every leg. At $899 for 9,858 km each way, that works out to about $46 per 1,000 km flown. That is about 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 7th — 1.6× the $550 we hold from New York. For context, the middle fare among the 49 routes of similar length we watch out of Los Angeles is $722. The best time to be in Buenos Aires: Oct–Dec · Mar–May.

Good to know

What is the cheapest month to fly from Los Angeles to Buenos Aires?
Across 4 months of cached-fare history, Nov 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 LA → 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We do not publish a number for this, because we cannot measure it yet.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, Nov comes out lowest on this route. Our guide Why flight prices change covers what does move a fare.
Are there nonstop flights from Los Angeles to Buenos Aires?
The current cheapest fares involve a connection, ticketed under United. 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.
