Cached-fare history: across 5 months, Mar is the cheapest for BKK → EZE. Best time to be there: Oct–Dec · Mar–May.
Fares bottom out in March around $1,553 and peak in October near $1,871 — a $318 spread across the 5 months we track. The cheapest itinerary we are tracking makes one stop and takes about 25 hours outbound, on a 10-night trip — ticketed under Ethiopian, which on a connecting fare need not operate every leg. At $1,553 for 16,868 km each way, that works out to about $46 per 1,000 km flown. That is about the $40 typical of ultra-long-haul fares here. Across the 12 departure cities we track at a similar distance from Buenos Aires, this fare ranks 5th — 17% above the $1,323 from Dubai. For context, the middle fare among the 17 routes of similar length we watch out of Bangkok is $1,434.

BKK → EZE, answered.
Is $1,553 a good price for Bangkok to Buenos Aires?
Only slightly. The seasonal median is around $1,735 round-trip and this fare is 10% under it, about $182. 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 Bangkok to Buenos Aires?
Across 5 months of cached-fare history, Mar 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 BKK → 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We do not publish a number for this, because we cannot measure it yet.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 5 months of cached fares, Mar comes out lowest on this route. See /guides/what-moves-a-flight-price/ for what does move a fare.
Are there nonstop flights from Bangkok to Buenos Aires?
The current cheapest fares involve a connection, ticketed under Ethiopian. 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.
