The full picture

The data shows a cheap, stable floor around $177 with a long tail reaching up to $279 — a 58% spread that counts as wide. That gap suggests this route alternates between a reliable low fare and occasional spikes, rather than drifting steadily upward or downward. With a median of $179 sitting just above the floor, it's clear that most of the 12 snapshots landed near the cheap end, with only a few pulling the average higher.

Because we only have 12 days of snapshots, we can't confidently map this spread to a specific booking window — 12 samples is a thin base for drawing conclusions about how far in advance to book. What we can say is that fares near $177–$179 showed up often enough to be treated as a realistic target, and the $279 figure looks more like an outlier or a fare captured during a less favorable snapshot window than a typical price.

We don't have enough visibility into carrier mix or day-of-week patterns to say anything credible about which airline dominates this route or whether weekday departures are cheaper — the data simply doesn't support that level of granularity here. The honest takeaway: if you see something close to $177–$179, that's consistent with the bulk of observed fares, and anything creeping toward $279 is on the expensive side of this particular sample. Treat this as a loose benchmark rather than a firm rule, given the small sample size and the real volatility baked into the 58% spread.
