Key takeaways

• Median fare of $331 across 30 days of cached snapshots — a reasonable anchor for budgeting

The full picture

Over 30 daily snapshots, IAD–CDG fares ranged from $242 to $393, with a median of $331. That's a 62% spread from low to high — wide enough that where you land in the range matters more than chasing a single "best" number. The middle 50% of observations (p25–p75) fell between $260 and $341, which is a more realistic planning band than the extremes on either end.

We don't have booking-window data showing how far in advance each fare was purchased — only a rolling 30-day window of cached cheapest fares. That means we can't responsibly claim prices "soften" at a specific number of weeks or months out. What the data does support is that meaningful discounts exist below the median: roughly a quarter of observed fares came in at $260 or under, so travelers with flexible dates and the patience to check repeatedly have a real shot at beating $331, not just hoping for it.

We don't have carrier-level detail in this dataset, so we can't speak to whether a specific airline on this route runs cheaper or pricier than competitors — that would be speculation. The honest takeaway: budget around the $331 median, treat anything near $260 as a strong deal worth booking quickly, and expect that waiting too long or searching only once could land you closer to the $393 high. The wide spread here is itself the main signal — this isn't a stable-price route, so checking fares across multiple days before committing is likely to pay off more than on routes with tighter spreads.
