Seattle → Toronto flights

Target $136–$160 on SEA→YYZ — and watch for sub-$120 windows

Key takeaways

• Median fare is $160 across 30 daily snapshots — a reasonable anchor for budget planning.
• Bottom-quartile fares sit at $136, meaning roughly one in four observed prices came in at or below that level.
• Floor of $110 was recorded at least once, signaling genuine sub-$120 deals exist but shouldn't be counted on.
• Spread of 256% between low and high ($110–$392) is exceptionally wide, suggesting fares are highly volatile and timing matters significantly.
• P75 is $199, so if you're seeing prices above $200, you're in the expensive quarter of observed fares — worth waiting or adjusting dates.

The full picture

The Seattle-to-Toronto corridor shows an unusually wide price spread — 256% between the observed floor ($110) and ceiling ($392) across 30 days of fare snapshots. That kind of range isn't noise; it's a signal that this route has real pricing variability, likely driven by a mix of connecting itineraries, load factors, and intermittent sale fares. The practical upshot: the route can be affordable, but you can also easily overpay if you book at the wrong moment. The median of $160 is your baseline. If you're seeing fares in that range, you're in normal territory. If fares are sitting closer to the p75 of $199 or above, the data suggests patience has historically been rewarded — about half of all observed fares came in below $160.

The $136 p25 threshold is the number worth anchoring to if you have flexibility. Fares at or below that level appeared in roughly the bottom quarter of observations, which means they're not rare flukes, but they're also not the default. Sub-$120 fares (approaching the $110 floor) did appear in the dataset but represent the tail of the distribution — treat them as a bonus if they materialize, not a planning assumption. There's no carrier-specific data in this snapshot set to draw firm conclusions about which airline drives the low-end fares, so shopping across all available options on any given search is advisable.

One honest caveat: 30 daily snapshots of cached lowest fares capture a moment-in-time picture, not a full seasonal cycle. The wide spread could reflect a mix of advance-purchase and last-minute fares, or simply different travel date windows being priced simultaneously. This data cannot tell you how far in advance to book with precision — only that fares as low as $136 have appeared, and fares as high as $392 have too. If your travel date is fixed, check fares regularly and act when you hit that $136–$160 zone.
