The full picture

Fares on this route have shown a fairly tight band over the observed window, with a median of $250 and a 20% spread between the $208 low and $250 high. That's a modest range — not the kind of volatility where waiting for a price drop is likely to yield dramatic savings, but enough that booking near the bottom quartile ($208) rather than the top is worth aiming for.

With only 12 days of snapshots, we can't confidently map how prices shift across a full booking horizon — there isn't enough history to say whether fares soften further out or firm up closer to departure. What we can say is that the bottom-quartile price ($208) and the median ($250) aren't far apart, so there isn't strong evidence of a narrow window where deals disappear. Travelers have a reasonable shot at landing near $208–$225 if they check fares periodically rather than booking the first price they see.

We don't have enough visibility into carrier mix or day-of-week patterns in this dataset to say whether a specific airline or weekday departure tends to run cheaper — the data simply doesn't support that level of granularity here. The honest caveat: with just 12 samples and a 20% spread, this snapshot is more a rough price range than a robust trend. Treat $250 as a reasonable ceiling to budget against, and $208 as an achievable target, but don't expect the kind of sharp booking-window signal that a larger dataset might reveal.
