Houston → Buenos Aires flights

Houston–Buenos Aires: median $440, floor near $366

Key takeaways

• Median fare is $440, based on 30 daily snapshots of cheapest cached prices
• Bottom quartile ($419 or less) shows up regularly enough to be a realistic target, not a fluke
• Prices have ranged from a $366 low to a $480 high — a fairly wide 31% spread
• That 31% spread suggests real day-to-day volatility, so flexible searching matters more than guessing a specific date
• Top quartile prices push past $446, worth avoiding if you can shift your search window

The full picture

Over the 30-day tracking window, IAH–EZE fares ranged from $366 to $480, with a median of $440. That's a 31% spread between low and high — wide enough to confirm this route sees genuine price movement rather than sitting flat. The bottom quartile ($419 and below) isn't a rare outlier; it represents roughly a quarter of the observed snapshots, so travelers who check in regularly have a realistic shot at landing near that range rather than paying the median.

We don't have booking-horizon data (how price changes as departure approaches) in this snapshot set — only a 30-day rolling window of cached fares. What we can say is that the gap between p25 ($419) and p75 ($446) is relatively narrow compared to the full low-high range, meaning most days cluster in the $419–$446 band, with occasional spikes toward $480 and occasional dips toward $366. That clustering suggests the median is a dependable planning number, while the extremes are less common but not negligible.

We don't have visibility into a dominant carrier or day-of-week patterns for this route in the current data, so we can't make claims about specific airlines or departure days without speculating. The honest takeaway: budget around $440, treat anything at or below $419 as a good deal worth booking, and be skeptical of paying near $480 unless your dates are fixed. The caveat worth repeating — this reflects 30 days of cached fare snapshots, not actual booking transactions, so it shows pricing trends rather than guaranteed availability at these exact prices.
