Fares cluster near $138 — but a wide $129–$234 range persists

Key takeaways

Median fare of $138 across 28 daily snapshots is a solid baseline for budgeting this route.
Bottom quartile fares run as low as $132, meaning roughly a quarter of observed days offered near-floor pricing.
The $234 high shows real upside risk if you shop later or during a demand spike.
An 81% spread between low and high is wide, so timing does matter more than usual on this route.
With 28 days sampled, this is a fairly reliable read, though it's still just one month's snapshot window.

The full picture

The data shows a median fare of $138 for Atlanta to Mexico City, with a low of $129 and a high of $234 — an 81% spread that's on the wider end for a route this short-haul. That gap tells us pricing isn't static: roughly a quarter of days sampled priced at or below $132 (the p25 mark), while the top quartile pushed well past $194. In practice, this means shoppers who check fares repeatedly rather than booking on the first search are more likely to land near the median or better.

We don't have granular day-by-day booking-window data (i.e., how price changes as departure approaches), so we can't say definitively when in the 0-to-330-day horizon prices soften most. What we can say is that the presence of a $129 floor alongside a $234 ceiling suggests fares fluctuate meaningfully even within a single month, which is consistent with a route that sees both leisure and business demand. Travelers with flexibility should treat anything at or below the $138 median as a reasonable target, and anything under $132 as a strong deal worth booking quickly.

No dominant carrier was identifiable in this dataset, so we can't speak to airline-specific pricing patterns or whether a single carrier is driving the low end or high end of the range. The honest caveat here: with 28 days of snapshots, this is a decent but not exhaustive sample — it captures one recent window, not a full seasonal cycle, so prices could shift with holidays, fuel costs, or schedule changes not reflected in this data.
