Seattle → Vancouver flights

Seattle–Vancouver fares center at $139 — budget $126–$152

Key takeaways

• $139 is the median cheapest fare across 30 daily snapshots — a reliable planning anchor for this short-haul route.
• The interquartile range runs $126–$152, meaning half of all observed fares landed in that narrow $26 band.
• The floor was $125 — only marginally below p25, suggesting rock-bottom deals are rare but achievable.
• A $193 high represents the ceiling observed; paying more than ~$155 on this route is a signal to wait or adjust dates.
• The 54% spread (low to high) is notable for a sub-200-mile route — prices are more volatile than the short distance might suggest.

The full picture

Seattle to Vancouver is one of North America's shortest international hops — roughly 140 miles — yet the 30-day fare snapshot shows a surprisingly wide price range, from $125 at the floor to $193 at the ceiling, a 54% spread. That volatility is worth paying attention to. The good news is that the interquartile range is comparatively tight: half of all sampled fares fell between $126 and $152, so most travelers who shop with even modest flexibility will land somewhere in that band. The $139 median is a credible target to plan around.

Because the p25 sits at just $126 — only $1 above the absolute low — the cheapest fares observed weren't flukes confined to a single outlier day; they appear to represent a genuine lower tier of pricing that surfaces with some regularity. Practically speaking, if you see a fare at or below $130, the data supports pulling the trigger rather than waiting for further drops. Conversely, fares above $155 — the upper reach of the interquartile range — historically represent the pricier end of this market, and patience or date flexibility is likely to pay off.

No dominant carrier pattern is identifiable from this dataset alone, so carrier-specific timing recommendations aren't warranted here. It's also worth noting that this route has a bus and rail alternative (Amtrak Cascades, Flixbus), which can act as a natural price ceiling — airlines rarely sustain fares much above what the ground option costs for long. One honest caveat: 30 snapshots capture a single rolling window and won't reflect seasonal spikes around major Vancouver or Seattle events, holiday weekends, or periods when the Cascades train sells out. Always cross-check fares against your specific travel dates before assuming the $139 median applies.
