The full picture

This short-haul route between Seattle and Vancouver shows a tight core pricing pattern: three-quarters of fares in our 30-day sample fell at or below $124, with a median of $111. That's a narrow band for a route this size, and it suggests the fare engine treats this corridor as fairly commoditized — likely reflecting steady competition and short flight time rather than dynamic demand-based pricing.

The headline spread of 86% looks dramatic, but it's almost entirely explained by the $184 high-water mark against a $99 floor. When most of your data (the p25–p75 range) sits inside a $25 window, one or two premium fares — often tied to a specific departure date, holiday period, or last-minute booking — can inflate the percentage spread without reflecting typical shopping conditions. In practice, a traveler booking on a random day in our window was far more likely to see something in the $99–$124 range than the $184 outlier.

We don't have carrier-level detail in this dataset, so we can't speak to which airline is driving the low fares or the outlier spike, and we can't isolate day-of-week patterns from these snapshots — doing so would require finer-grained data than 30 aggregate daily observations. The honest takeaway: this is a low-volatility route where waiting for a 'deal' is unlikely to save much beyond a few dollars, since the median and bottom quartile are already close together. Budget around $111, and don't stress the booking calendar too hard for this one.
