Houston → Santiago flights

Houston–Santiago fares cluster near $431 — act when $376 appears

Key takeaways

• Median fare is $431, based on 7 daily snapshots of the cheapest cached fares — treat this as your baseline expectation.
• The low of $376 is the only meaningful discount visible in this window — roughly 13% below median, worth acting on quickly.
• Both p25 and p75 land at $431, meaning the vast majority of observed fares were flat at the median — very little variance day to day.
• Spread is 15%, which sits right at the threshold between a 'tight' and 'volatile' market — not enough data to call a clear trend.
• Sample size is only 7 days — conclusions here are directional, not definitive; monitor fares actively before committing.

The full picture

The Houston-to-Santiago market is showing an unusually compressed fare distribution across the 7 snapshots we have. With both the 25th and 75th percentiles landing exactly at the $431 median, virtually every observed day priced at the same level — the $376 low is a genuine outlier rather than a pattern you can reliably time toward. That $55 gap between the floor and the median represents about 13% savings, which is meaningful on a long-haul South American route, but it appeared only rarely in this window.

Because the spread sits at exactly 15% — the lower boundary of what analysts typically call a 'volatile' market — there is a theoretical possibility that fares do move, but the current data doesn't give us enough observations to identify when or why. On routes of this length (roughly 8–10 hours nonstop or longer with a connection), fares tend to be most competitive 6–10 weeks before departure as carriers manage load factors, and they typically firm up sharply inside 3 weeks. If $431 is your reference point, watching for any dip toward the $376–$400 range and booking promptly is a reasonable strategy.

Day-of-week patterns and carrier-specific behavior are not visible from this dataset, so we won't speculate on those fronts. The honest caveat here is significant: 7 data points is a thin sample for a route with this much potential for fare movement driven by seasonality, currency shifts (USD/CLP fluctuations affect competitive pricing), and network schedule changes. Treat the $431 median as a credible anchor, but revisit this data once more snapshots accumulate before drawing firm conclusions.
