Cached-fare history: across 4 months, Nov is the cheapest for LON → EZE. Best time to be there: Oct–Dec · Mar–May.
Fares bottom out in November around $1,067 and peak in December near $1,427 — a $360 spread across the 4 months we track. The cheapest itinerary we are tracking makes 2 stops and takes about 16.5 hours outbound, on a 7-night trip — ticketed under Ryanair, which on a connecting fare need not operate every leg. At $1,067 for 11,155 km each way, that works out to about $48 per 1,000 km flown. That is above the $40 typical of ultra-long-haul fares here. Across the 31 departure cities we track at a similar distance from Buenos Aires, this fare ranks 21st — 50% above the $712 from Los Angeles. For context, the middle fare among the 30 routes of similar length we watch out of London is $642.

How far in advance should I book LON → 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We do not publish a number for this, because we cannot measure it yet.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. See /guides/what-moves-a-flight-price/ for what does move a fare.
Are there nonstop flights from London to Buenos Aires?
The current cheapest fares involve a connection, ticketed under Ryanair. 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.
