San Francisco → Paris flights

SFO–CDG median is $427 — bottom-quartile fares start at $383

Key takeaways

• $427 is the median one-way (or roundtrip basis — see caveat) fare across 17 daily snapshots for SFO–CDG.
• The bottom quartile threshold is $383 — fares at or below that level represent the better-value end of what this data window captured.
• The floor was $350, suggesting occasional dips are real but not the norm; don't anchor your plans to that number.
• A 27% spread between low and high ($350–$445) is moderate — meaningful enough that timing and flexibility can save roughly $95 on this route.
• With only 17 sample days, treat these figures as directional rather than definitive; a fuller 30-day window would sharpen confidence.

The full picture

The SFO–Paris corridor shows a relatively tight fare band in this snapshot window: a $350 floor, a $445 ceiling, and a median of $427. That 27% spread is moderate — wide enough to make monitoring worthwhile, but not the kind of volatile route where fares swing by hundreds of dollars overnight. If you see anything at or below the p25 threshold of $383, that's a credibly good fare by recent standards and worth acting on rather than waiting for further drops.

On booking timing, the $350 low demonstrates that sub-$400 fares do surface on this route, but the cluster of prices between $383 and $438 (the interquartile range) suggests they're the exception rather than the rule. Transatlantic routes to Paris from the West Coast have historically softened in the booking window of roughly 6–10 weeks out for off-peak travel, and tightened sharply inside three weeks as seats fill. Without departure-date metadata in this dataset, that general principle is the best guidance available here — the data confirms a price floor exists, but doesn't pinpoint exactly when it appears.

No dominant carrier is identifiable from this dataset, so route-specific airline advice would be speculative. SFO–CDG is served by Air France, United, and occasionally consolidator fares on connecting itineraries, which can explain why the floor dips as low as $350. One honest caveat: 17 samples is a thinner-than-ideal window. The median and quartile figures are directionally useful, but a full 30-day rolling dataset could shift the median by $20–40 in either direction. Use $383 as your mental target, set a fare alert, and don't assume the $350 low is reliably repeatable.
