The full picture

Boston–Paris is a competitive transatlantic corridor, and the 30-day fare data reflects that dynamic clearly. The median of $339 is a solid anchor for budgeting, but the 46% spread between the observed low ($294) and high ($430) tells a more interesting story: this route isn't priced uniformly, and fares shift enough that when you buy — and how flexible you are about departure timing — can move the needle by more than $100.

The interquartile range ($310–$348) is notably compressed relative to the full spread. That means the market spends most of its time in a fairly narrow band, but genuine outlier-low fares in the $294–$310 zone do appear — they just don't linger. Historically on long-haul transatlantic routes, fares to European hubs like Paris tend to soften in the 6–10 week window before departure as carriers adjust unsold inventory, and again briefly in the 3–4 week window if load factors underperform. Booking inside two weeks, however, typically pushes fares toward the high end of the observed range.

No dominant carrier was identifiable from the available data, so fare-shopping across carriers via a flexible-date search tool is worthwhile on this route — the $294 floor is likely not exclusive to one airline. One honest caveat: 30 snapshots capture a single rolling window and may not reflect seasonal demand shifts, such as peak summer or holiday surges, which could push fares well above the $430 high observed here. Use these numbers as a calibration tool for off-peak or shoulder-season travel, not as a guarantee for any departure date.
