IAH–Cancún hovers near $133 — most fares cluster tight

Key takeaways

• Median fare sits at $133, with the bottom quartile also at $133 — the cheapest prices aren't rare outliers, they're common.
• Middle 50% of fares (p25–p75) are squeezed into a narrow $133–$140 band.
• Low end of the range hit $122, just $11 below the median — modest savings for patient searchers.
• High end spiked to $175, roughly 32% above median — likely a handful of pricier snapshot days.
• Overall spread of 43% is wide for this short-haul route, driven mostly by those occasional high-fare days rather than typical pricing.

The full picture

Over 30 daily snapshots, IAH–Cancún fares showed a median of $133, with half of all observed prices falling between $133 and $140 — a tight cluster that suggests $133–$140 is a realistic target for most booking windows rather than a lucky break. The $43% spread looks dramatic on paper, but it's driven by a thin tail of higher fares (up to $175) rather than broad volatility across the data set; the bulk of snapshots sit close to the floor.

We don't have booking-window data (days-before-departure) in this dataset, only a rolling 30-day sample of cached fares, so we can't say definitively when in the booking horizon prices soften. What we can say is that low fares near $122–$133 appeared often enough to be the median, not an anomaly — meaning travelers monitoring this route over a few weeks have a reasonable shot at catching one of the typical lower-priced snapshots rather than needing to time a narrow sale window.

No single dominant carrier was visible in this data, so we can't speak to airline-specific patterns or day-of-week effects — there simply isn't a carrier field or date-level granularity provided. The honest takeaway: this route is fairly stable and cheap most of the time, with the median essentially matching the 25th percentile, but a real risk of hitting a $160–$175 fare exists on a subset of days. Treat $133 as your benchmark and be ready to book if you see anything at or below that; anything approaching $175 is on the expensive side for this market based on the last 30 days of pricing.
