Seattle → Vancouver flights

Budget $112–$145 for Seattle–Vancouver; $89 is possible but rare

Key takeaways

• Median fare is $116, making this a modestly priced short-haul corridor between Seattle and Vancouver.
• The interquartile range sits at $112–$145 — if you land anywhere in that band, you're doing as well as most travelers in this dataset.
• The floor of $89 was observed, but it sits well below the 25th percentile, signaling it's an outlier worth monitoring rather than expecting.
• The high of $212 — nearly 2.4× the low — reflects real volatility; a spread of 138% means timing and flexibility matter on this route.
• With 30 daily snapshots powering these figures, the sample is solid enough to trust the central tendency, though a longer window would sharpen seasonal patterns.

The full picture

Seattle to Vancouver is a short hop — under three hours by air — yet the fare data shows a surprisingly wide swing. The $112–$145 interquartile range is a reasonable planning target: roughly half of the cheapest daily fares in the 30-day snapshot window fell inside that band. The $116 median is the most defensible single number to budget around. The $89 floor is real but rare; chasing it exclusively risks missing reasonable mid-range fares that still represent solid value on a sub-200-mile route.

On a corridor this short, prices tend to respond sharply to load factors because the pool of competing itineraries is thin — there are few connecting-flight alternatives to dilute demand the way a long-haul route might. That dynamic likely explains the 138% spread between low and high. Practically, this means booking 3–6 weeks out is a reasonable default: close enough that airline inventory is well-established, far enough that last-minute scarcity pricing hasn't kicked in. If the fare is in the $112–$116 range and your dates are fixed, the data suggests taking it rather than waiting.

Day-of-week and carrier patterns aren't directly visible in this dataset, so we won't speculate on them. What the data does support is a simple heuristic: set a fare alert at $116 (the median) and treat anything at or below $112 (the 25th percentile) as a strong buy signal. One honest caveat: 30 snapshots capture one rolling month of cached fares, not a full seasonal cycle. Holiday periods, summer peaks, and cross-border event traffic could push fares meaningfully above the $145 75th-percentile mark — the $212 high in the dataset is a reminder that the ceiling is real.
