DFW–Boston fares cluster near $239, with upside risk to $323

Key takeaways

Median fare is $239, and the 25th percentile is also $239 — meaning a large share of observed fares cluster right at the floor.
Top quartile reaches $273, a reasonable ceiling for a solid deal if the floor isn't available.
High end spikes to $323, a 45% spread from the low of $222 — this route can get notably more expensive at times.
Spread of 45% is wide enough to make timing matter more than usual on this route.
Only 12 snapshots were sampled, so treat these numbers as a directional read rather than a precise forecast.

The full picture

The data shows a tight cluster of cheap fares near $239, with the 25th percentile matching the median almost exactly — a sign that a meaningful share of search days land right around that price. But the range extends up to $323, a 45% spread from the $222 low, which tells us this route has real volatility rather than a flat, predictable fare curve. If you see something at or near $239, that's a solid price by this route's own history, not just a guess.

With only 12 daily snapshots, we can't responsibly point to a specific booking window where prices reliably soften — that would be reading more precision into the data than it supports. What we can say is that the gap between the median ($239) and the high ($323) is large enough that waiting too long, or searching during a high-demand window, carries real upside risk. Shoppers who lock in close to the $239–$273 range (the bottom three quartiles) are capturing the typical price on this route; anything pushing toward $300+ is in outlier territory based on what we've observed.

No dominant carrier was identifiable from this dataset, so we can't speak to airline-specific pricing patterns or whether one carrier is driving the high end. The honest caveat here is sample size: 12 snapshots is a thin window, and a 45% spread on a small sample means a couple of unusual fare days could be skewing the high end. Treat $239 as a good anchor price, but don't assume the exact shape of this distribution would hold up over a longer observation period.
