Seattle → Paris flights

Seattle–Paris: target $289–$345 and watch for dips below $300

Key takeaways

• Median fare is $345, based on 30 daily snapshots of the cheapest available cached fares.
• The bottom quartile tops out at $289, meaning roughly one-in-four observed fares came in at or below that level — a realistic target for patient bookers.
• The spread is 48% (low $287, high $425), which is wide enough that timing your purchase meaningfully affects what you pay.
• The p25–p75 interquartile range is $289–$353, so most competitive fares cluster within that $64 band rather than near the $425 ceiling.
• Fares below $300 do appear in the data (low: $287), but they represent the thin edge of the distribution — treat them as opportunistic, not guaranteed.

The full picture

The 30-day snapshot for Seattle (SEA) to Paris Charles de Gaulle (CDG) tells a fairly clear story: there is real money at stake in when you pull the trigger. With a $138 gap between the observed low ($287) and high ($425) and a spread of 48%, this is not a route where prices are tightly compressed — what you pay depends heavily on when you happen to be looking. The interquartile range of $289–$353 is the most actionable signal here: the majority of competitive fares land in that zone, and anything in the low-$300s should be considered a solid booking rather than a reason to wait.

On a transatlantic route of this length, pricing typically follows a curve where fares are most volatile in the window beyond three months out (airlines adjusting inventory) and again inside three weeks (last-minute yield management pushing prices up). The $345 median suggests the market is not deeply discounted right now, but the presence of fares in the high $280s indicates that softer-price windows do open. Checking fares consistently over a two-to-four week period — rather than booking on a single impulse check — gives you a reasonable chance of landing in the bottom quartile. Setting a fare alert at or below $310 is a defensible strategy given this distribution.

One honest caveat: 30 daily snapshots capture the cheapest cached fare each day, not every fare across all booking classes or departure dates. The low of $287 may reflect a specific travel window, cabin configuration, or connection routing that doesn't match your needs. The range here describes what the market has offered in aggregate, not a guarantee of what you'll find for your exact itinerary. Use the median and p25 as calibration benchmarks, not as prices you can simply claim on demand.
