SFO–CDG: Target $356–$410 and watch for dips toward $352

Key takeaways

• Median fare is $410 across 30 daily snapshots — a reasonable baseline for budgeting SFO–CDG.
• Bottom-quartile fares sit at $356, meaning roughly one in four snapshots caught prices at or below that level — a realistic target for flexible shoppers.
• The low of $352 shows the floor is achievable, though it appeared infrequently enough that counting on it carries real risk.
• A 51% spread between low ($352) and high ($532) signals meaningful price volatility — timing your search does matter on this route.
• The p25–p75 interquartile range is $356–$432, so most 'good' fares cluster in a $76 band; anything under $380 is worth snapping up.

The full picture

The SFO–CDG fare landscape across our 30-day snapshot window is notably volatile, with a 51% spread between the floor ($352) and ceiling ($532). That kind of range — roughly $180 separating the best and worst days to buy — means this is a route where active monitoring pays off. The median of $410 is your anchor: fares above $450 are drifting into expensive territory, while anything in the $352–$380 band represents a genuine deal by the standards of this data set.

The interquartile range of $356–$432 tells a practical story: the middle half of all observed fares fell within a $76 window, which is tighter than the full spread implies. That clustering suggests $410 isn't just a statistical midpoint — it's close to what the market consistently offers. Historically on transatlantic routes, fares tend to soften in the 6–10 week window before departure as carriers adjust unsold inventory, and again at the 3–4 month mark when promotional fares first appear. Our data doesn't capture booking-lead-time directly, but the presence of fares as low as $352 suggests those windows do open on this route.

No dominant carrier signal is present in this data set, so we can't point to a specific airline as the consistent price leader. Set fare alerts at $380 as your trigger price — that sits comfortably below the p25 threshold and gives you a margin of safety above the absolute low. One honest caveat: 30 snapshots capture a single rolling window and may not reflect seasonal demand shifts around major holidays or peak summer travel; if your travel falls in June–August or around school breaks, expect the distribution to shift meaningfully upward.
