Fares bottom out in December around $995 and peak in September near $1,286 — a $291 spread across the 4 months we track. The cheapest itinerary we are tracking makes one stop and takes about 14 hours outbound, on a 8-night trip — ticketed under Air Europa, which on a connecting fare need not operate every leg. At $995 for 9,627 km each way, that works out to about $52 per 1,000 km flown. That is above the $44 typical of long-haul fares here. Across the 27 departure cities we track at a similar distance from Buenos Aires, this fare ranks 17th — 1.6× the $617 we hold from Mexico City. For context, the middle fare among the 32 routes of similar length we watch out of Lisbon is $797.

LIS → EZE, answered.
Is $995 a good price for Lisbon to Buenos Aires?
Only slightly. The seasonal median is around $1,200 round-trip and this fare is 17% under it, about $205. 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 Lisbon to Buenos Aires?
Across 4 months of cached-fare history, Dec 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 LIS → 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We do not publish a number for this, because we cannot measure it yet.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, Dec comes out lowest on this route. See /guides/what-moves-a-flight-price/ for what does move a fare.
Are there nonstop flights from Lisbon to Buenos Aires?
The current cheapest fares involve a connection, ticketed under Air Europa. 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.
