Bottom quartile fares of $362 or less represent the best realistic value in this dataset
20% spread between low and high — a moderate range, not a volatile one
Low of $339 was the single best fare seen, but it's an outlier against a tight cluster near $400

The full picture

The data shows a fairly narrow band for Seattle–Phuket fares: a median of $398, with 75% of observed prices falling between $362 and $400. That's a 20% spread between the $339 low and $406 high — moderate, but not the kind of wide swing that rewards aggressive timing. In practice, this means most travelers booking during a similar window should expect to pay close to the median, with the $362-or-under bottom quartile representing a genuinely good deal rather than the norm.

With only 12 daily snapshots, we can't confidently map how prices evolve across a full booking horizon — there isn't enough history here to say whether fares soften further out or firm up closer to departure. What we can say is that the cluster of prices near $400 suggests a stable fare environment during the period observed, with the $339 low likely reflecting a short-lived promotional fare or a single lower-cost itinerary rather than a repeatable pattern.

No dominant carrier or day-of-week pattern is visible in this dataset, so we can't make claims about specific airlines or departure days driving the price differences. The honest takeaway: treat $398 as a reasonable budget for this route, watch for anything under $370 as a good opportunity, and don't expect dramatic savings by shifting your booking date within a similar window — the data simply doesn't support that level of precision with only 12 samples.
