Houston → Santiago flights
Median fares on IAH–SCL sit at $431, but the bottom quartile dips to $294 — a 32% gap that rewards flexible travelers who monitor prices early.
Target $294–$431 for Houston–Santiago; patience pays here
Key takeaways
- $431 is the median fare across 30 daily snapshots — a reliable planning anchor for Houston–Santiago.
- Bottom-quartile fares reached as low as $294, meaning roughly one-in-four snapshots captured something meaningfully cheaper.
- The top quartile climbs to $471 or higher, so waiting too long without a price alert risks paying 36% more than the bottom quartile.
- A 118% spread between the absolute low ($269) and high ($586) is exceptionally wide, signaling this route is volatile and worth tracking over time rather than booking on impulse.
- The $269 floor appears to be an outlier — budget closer to $294–$431 to avoid disappointment.

The full picture
Houston–Santiago is one of the longer thin-market routes in Latin America, and the pricing data reflects that reality. With a median of $431 and a spread of 118% between the observed low ($269) and high ($586), fares here move in a wide band. The interquartile range — $294 to $471 — is the more practical planning window: it represents the middle 50% of observed pricing and suggests you can reasonably expect to land somewhere in that zone if you're attentive. The $269 floor is real but rare; treat it as a lucky-catch price rather than a target.
On a route with this much price volatility, booking horizon matters more than day-of-week patterns (which this dataset does not surface). Generally on long-haul South American routes, fares tend to be most competitive in the 6–10 week window before departure — early enough that carriers are still filling seats, but past the period when premium demand from corporate travelers keeps prices elevated. Setting a price alert at or below the $294 p25 mark gives you a data-grounded trigger: if a fare hits that threshold, the snapshot history suggests you're in the bottom quartile of what this route typically offers.
One honest caveat: 30 daily snapshots capture the cheapest cached fare available on each day, not every fare class or departure date combination. Seasonal demand shifts — southern hemisphere summer (December–February) and Chilean national holidays — can push fares well above the observed high of $586, patterns that a 30-day window may not fully capture. Use this data as a directional guide, not a guarantee, and revisit your price alert if your travel dates fall in peak season.
