The full picture

Over the 26 days we tracked, fares from Houston to Buenos Aires ranged from $366 to $480, with a median of $419. That's a 31% spread from low to high — wide enough to suggest timing matters, but not so extreme that you should expect rock-bottom outlier fares to show up often. The bottom quartile of fares (at or below $366) represents a realistic target if you have flexibility, while the top quartile ($443 and up) is what you risk paying if you book during a pricier stretch.

We don't have booking-date metadata in this dataset — only snapshot prices over a 30-day window — so we can't say definitively when in the booking horizon (e.g., 2 months out vs. 2 weeks out) prices soften. What we can say is that roughly a quarter of the days we observed had fares at or below $366, meaning opportunities below median do appear with some regularity. If your travel dates are flexible, checking fares every few days and being ready to book when you see something in that bottom-quartile range is a reasonable strategy based on this data.

We don't have visibility into a dominant carrier or specific day-of-week patterns for this route — the data only reflects cached cheapest-fare snapshots, not itinerary-level detail. Caveat: 26 days is a decent sample but still just one month-long window: seasonal demand (especially given Buenos Aires' being a long-haul leisure market) could shift this range meaningfully at other times of year. Use these numbers as a reasonable benchmark for near-term booking, not a year-round guarantee.
