The full picture

Fares between Seattle and Rome have ranged from $321 to $436 over the observed period, with a median of $385. That 36% spread between low and high is wide enough to suggest there's real money on the table for travelers who can be flexible — the gap between a p25 fare of $336 and a p75 fare of $428 is nearly $100, which is meaningful for a transatlantic itinerary.

With only 12 snapshots, we can't confidently map out a booking curve or identify a reliable window where prices consistently soften — that would require a longer observation period. What we can say is that fares below $350 represent the bottom quartile historically, and are worth booking when seen rather than waiting for something better. Fares creeping above $420 are in top-quartile territory, and there may be room to wait or search alternate dates.

We don't have enough visibility into carrier distribution or day-of-week patterns in this dataset to make claims about specific airlines or departure days — any such claims would be speculative given the sample size. The honest takeaway: this route shows meaningful price variability, but with only 12 data points, treat the $385 median as a rough anchor rather than a precise target, and prioritize grabbing fares that fall into the lower half of the observed range.
