Seattle → Paris flights

Target $302 on SEA–CDG — but act fast when fares dip to $210

Key takeaways

• Median fare is $302, based on 30 daily snapshots of the cheapest cached fares on this route.
• Bottom quartile fares fall at or below $210 — meaning roughly one in four observations hit that floor, so low fares do appear with some regularity.
• The spread is 106% (low $210 to high $433), indicating this route is highly volatile and timing your purchase meaningfully affects what you pay.
• $340 is the 75th-percentile threshold — if you're seeing fares above that, you're in the more expensive tier and may benefit from waiting or adjusting travel dates.
• Fares below $260 represent genuine deals on this route and are worth booking immediately when spotted, given how quickly prices can revert.

The full picture

The Seattle–Paris fare landscape over our 30-day snapshot window is one of the more volatile transatlantic routes we track. With a spread of 106% between the observed low ($210) and high ($433), what you pay depends heavily on when you look. The median of $302 is a useful anchor: fares near or below that figure are reasonable, while anything north of $340 — the 75th percentile — puts you in territory where a modest amount of patience or date flexibility is likely to pay off.

The bottom quartile sitting at $210 is genuinely encouraging. It tells us that low fares appear frequently enough to be realistic targets, not just one-off anomalies. That said, the $210 floor isn't guaranteed to persist — the wide spread suggests these fares are episodic, driven by airline promotions or demand softness on specific departure dates rather than a structural pricing floor. When you see a fare in the $210–$260 range, treat it as actionable. If you're sitting above $340, it's worth monitoring the route for a week or two before committing.

No dominant carrier was distinguishable from this dataset, so we can't point to a specific airline as the most reliable source of low fares on SEA–CDG. In general on long-haul transatlantic routes, fares tend to soften 4–8 weeks before departure for off-peak travel and 2–4 months out for peak summer periods — but this data doesn't capture the booking-horizon dimension directly, so treat that as general context rather than a route-specific finding. One honest caveat: 30 daily snapshots capture fare availability at a single point in time each day; actual bookable fares shift continuously, and your results may vary depending on travel dates, departure time, and connection preferences.
