The full picture

The data shows a $482 median fare for Denver to Frankfurt, but the headline 48% spread is misleading on its own — it's driven by a handful of high-end outliers reaching $649, not by broad day-to-day volatility. Look at the interquartile range instead: half of all sampled fares fell between $470 and $486, a tight 3% band. That's the more realistic picture of what you'll pay on a typical search.

This pattern — a narrow core range with occasional expensive spikes — typically reflects a mix of normal fare classes alongside last-minute or high-demand pricing bleeding into the sample. With 28 daily snapshots, we have decent coverage, but we can't isolate a specific booking window within that period where prices reliably dropped; the data shows fare levels across the 30-day span, not a trend tied to days-before-departure. So rather than chasing a particular day to book, treat anything at or below the $470 mark as a strong price worth taking, and treat quotes creeping toward $600+ as outliers to wait out or route around.

We don't have carrier-level detail in this dataset, so no airline-specific booking pattern can be confirmed here. The honest takeaway: this route has a stable, predictable core price near $480, with infrequent spikes that skew the range — not a market where timing tricks are likely to save you much beyond simply avoiding those high outliers.
