Seattle to PVG fares have a median of $441 over 30 days; most quotes land between $419 and $445, so book when you see that range rather than waiting.

The data shows a route that mostly behaves consistently, with occasional sharp spikes. Half of all 30 snapshots came in at or below $441, and the bottom quartile sits in a narrow $419–$445 band — a difference of just $26. That tight clustering suggests this is the realistic price floor for Seattle–PVG economy fares right now, rather than a rate you need to chase or time perfectly.
The headline spread of 89% is driven almost entirely by the $791 high, which sits far outside the p75 of $445. That kind of gap usually reflects a handful of days with sold-out low fare buckets or a last-minute pricing anomaly, not a gradual upward drift as departure approaches. Because we only have 30 days of snapshots rather than a full multi-month booking curve, we can't say with confidence whether fares reliably soften at a particular point in the booking window — what we can say is that low-$400s pricing showed up often enough to be the realistic target, while anything creeping toward $500+ should be treated as a warning sign rather than normal fluctuation.
No dominant carrier or day-of-week pattern was visible in this dataset, so we can't responsibly make claims about specific airlines or booking days — doing so would go beyond what the data supports. The practical takeaway: watch for fares in the $419–$445 range and book when you see them, since that band represents the bulk of real pricing. The caveat worth repeating is that with only 30 data points and one extreme outlier skewing the spread, this snapshot is useful as a directional guide but not a guarantee of future pricing behavior.
Why we regenerated this article: Price spread widened by 57 points. We only rewrite when the underlying price index actually moves — stable weeks keep the previous take.
