• Bottom quartile (25th percentile) sits at just $131, a realistic target if you monitor for a few days
• Top quartile fares climb to $184, and the observed high hit $205

The full picture

Over 30 days of cached fare snapshots, DFW–Cancún fares showed a median of $138, but the range tells a more interesting story: prices swung from a low of $119 to a high of $205, a 72% spread from floor to ceiling. That's a wide gap for a leisure route this well-traveled, and it suggests fares here are more volatile than routes where spread runs under 20%. The bottom quartile — fares at or below $131 — represents roughly a quarter of all snapshots, so paying under $131 isn't a fluke, it's a realistic target if you have some flexibility in when you buy.

We don't have booking-date metadata in this dataset — only snapshots of cached cheapest fares over a 30-day window — so we can't say definitively that prices soften at a specific point in the booking horizon (say, 3 weeks out vs. 8 weeks out). What we can say is that the spread between p25 ($131) and p75 ($184) is wide enough that shopping around and checking fares on multiple occasions before booking is likely to pay off more here than on a route with a tighter band. If you see something at or near the $131–138 range, that's solidly in the better half of what this route has offered; anything creeping toward $184 or above is in the expensive tail.

No single carrier or day-of-week pattern is visible in this data, so we won't speculate about which airline or weekday tends to be cheaper — those patterns may exist, but we don't have the visibility to confirm them here. The honest caveat: 30 snapshots is a reasonable sample for a median, but it's still a snapshot of one 30-day window, not a seasonal history, so treat these numbers as a current-conditions read rather than a year-round guarantee.
