Seattle–Dublin fares held flat at $474 — little room to time it

Key takeaways

$474 was the only price observed — no variation across the entire sample
0% spread between low, median, and high means no 'cheap window' stood out
Only 6 snapshots were collected, so this is a thin sample — treat it as a baseline, not a trend
No carrier or day-of-week patterns are visible given the flat pricing and small sample
If $474 is within your budget, there's no data-backed reason to wait for a drop

The full picture

The data for this route is unusually flat: all 6 snapshots returned the exact same fare of $474, with zero spread between the low, median, and high. That's a strong signal of price stability over the window we observed, but it also means we can't point to a 'bottom quartile' moment or a softer booking window — there simply wasn't any variation to analyze.

Normally we'd talk about when in the booking horizon prices tend to ease, or whether certain departure days trend cheaper. With this dataset, none of that is visible — either because the fare is cached/pinned at a single price point by the source, or because the route genuinely didn't fluctuate during these 6 days of snapshots. Both are plausible, and we can't distinguish between them from the data alone.

The honest takeaway: with only 6 samples and no price movement at all, this read is more of a snapshot than a trend. We'd treat $474 as a reasonable reference price for SEA–Dublin, but we don't have enough data here to make a confident claim about timing your purchase for a better deal. If you're planning this trip, it's worth checking back for a larger sample before assuming $474 is as good as it gets — or as bad.
