Houston → Cancun flights

IAH–Cancún hovers near $140 — bottom quartile hits $129

Key takeaways

• Median fare of $140 across 30 daily snapshots gives a solid baseline for budgeting this route.
• Bottom-quartile fares ($129 or less) show up regularly enough to be worth waiting for if your dates are flexible.
• Low of $115 marks the floor seen in this window — treat anything near that as a strong deal.
• Spread of 44% between low and high is fairly wide, meaning timing and search flexibility matter more than usual on this route.
• High of $166 still isn't dramatic for a Gulf-to-Caribbean route, so even 'expensive' days here are moderate.

The full picture

Over 30 days of tracked fares, IAH–Cancún prices ranged from $115 to $166, with a median of $140. That 44% spread is on the wider side, which tells us this route doesn't have a single stable 'going rate' — prices move enough that shopping around across multiple days can meaningfully change what you pay. The bottom quartile ($129 and below) appears often enough in the data that it's a realistic target rather than a rare fluke, while the top quartile above $162 represents days worth avoiding if you have flexibility.

We don't have visibility into how prices shift across the full booking horizon (i.e., 60 days out vs. 14 days out) — our data is a 30-day rolling snapshot of cached fares, not a forward-looking booking curve. What we can say is that within this window, fares fluctuate enough that checking on multiple days before committing is likely to save you $10–$20 versus booking on a random high day. Treat the median as your benchmark: if you see something at or below $129, that's a good sign; if you're staring at $160+, it's worth waiting a few days to see if the price softens.

No dominant carrier was distinguishable in this data, so we can't speak to airline-specific pricing patterns or day-of-week effects — the sample doesn't break out that level of detail. The honest caveat: with 30 data points and a 44% spread, this is a reasonably sized sample, but it reflects one snapshot period, not a seasonal or year-round trend. Prices around holidays or peak Cancún travel months (winter, spring break) could easily push outside this $115–$166 band.
