The full picture
The data for Washington (DCA) to Edinburgh (EDI) shows a single, unmoving price point: $348 across every one of the 7 daily snapshots we have. There's no spread at all — low, median, p25, p75, and high are all the same number. That's unusual, and it likely means either the route has very limited fare inventory being cached, or the cheapest available fare simply hasn't changed during this short window.
With only 7 days of samples, we can't responsibly talk about a booking horizon — whether prices soften closer to departure or reward booking months out. A reliable read on timing typically needs 30+ days of snapshots to separate real patterns from noise, and we're well short of that here. Similarly, we have nothing to say about day-of-week effects or a dominant carrier, since neither is visible in this dataset.
The honest takeaway: $348 is the only price we've observed, so it's a reasonable reference point if you need to book soon, but treat it as a snapshot rather than a trend. We'd recommend revisiting this route once more daily data accumulates — right now, the sample is too thin and too flat to support any claims about the best time to buy.
