Cached-fare history: across 5 months, Nov is the cheapest for BRU → EZE. Best time to be there: Oct–Dec · Mar–May.
Fares bottom out in November around $987 and peak in December near $1,579 — a $592 spread across the 5 months we track. The cheapest itinerary we are tracking makes 2 stops and takes about 16.5 hours outbound, on a 16-night trip — ticketed under SWISS, which on a connecting fare need not operate every leg. At $987 for 11,333 km each way, that works out to about $44 per 1,000 km flown. That is about the $40 typical of ultra-long-haul fares here. Across the 30 departure cities we track at a similar distance from Buenos Aires, this fare ranks 14th — 39% above the $712 from Los Angeles. For context, the middle fare among the 27 routes of similar length we watch out of Brussels is $802.

BRU → EZE, answered.
Is $987 a good price for Brussels to Buenos Aires?
Only slightly. The seasonal median is around $1,195 round-trip and this fare is 17% under it, about $208. 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 Brussels to Buenos Aires?
Across 5 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 BRU → 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We do not publish a number for this, because we cannot measure it yet.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, Nov comes out lowest on this route. See /guides/what-moves-a-flight-price/ for what does move a fare.
Are there nonstop flights from Brussels to Buenos Aires?
The current cheapest fares involve a connection, ticketed under SWISS. 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.
