Best time to be in Buenos Aires: Oct–Dec · Mar–May. Fare history for this route is still thin, so we make no seasonal call yet.
The cheapest itinerary we are tracking makes 2 stops and takes about 31.5 hours outbound, on a 7-night trip — ticketed under Cathay Pacific, which on a connecting fare need not operate every leg. At $1,734 for 18,363 km each way, that works out to about $47 per 1,000 km flown. That is above the $40 typical of ultra-long-haul fares here. Across the 10 departure cities we track at a similar distance from Buenos Aires, this fare ranks 7th — 26% above the $1,373 from Shanghai. For context, the middle fare among the 7 routes of similar length we watch out of Tokyo is $1,564. 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.

TYO → EZE, answered.
How far in advance should I book TYO → 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We do not publish a number for this, because we cannot measure it yet.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. See /guides/what-moves-a-flight-price/ for the levers we can measure.
Are there nonstop flights from Tokyo to Buenos Aires?
The current cheapest fares involve a connection, ticketed under Cathay Pacific. Nonstop options exist on many dates at higher prices — check the live search for your exact dates.
Are these prices guaranteed?
No — these are cached fares found on real searches (this one on September 1). 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.
