The full picture

This route's pricing is fairly stable: a 23% spread between low and high fares means there's some room to save, but not the kind of wild swings that reward obsessive fare-watching. With a median of $351 and a bottom quartile around $295, travelers should treat anything at or below $300 as a strong fare worth booking rather than holding out for a dramatically better deal — the data doesn't support one.

Because this sample only covers 12 snapshots, we can't responsibly point to a specific booking window (like '6 weeks out' or '3 months ahead') as optimal. What we can say is that the fares we observed didn't move in a single direction — they fluctuated within the $295–$363 band throughout the window, suggesting prices soften and firm up periodically rather than following a clean downward-then-spiking curve. If you see a fare near the p25 mark of $295, that's a reasonable signal to act, since it sits meaningfully below the median.

We don't have enough carrier-level detail in this dataset to identify a dominant airline or flag carrier-specific booking behavior (like fare-sale cadences or schedule changes). Day-of-week patterns also aren't reliable here — with only 12 data points, any apparent Tuesday-is-cheaper pattern would be statistical noise, not signal. The honest takeaway: this is a moderately tight fare range with a clear below-median target ($295–$300), but the small sample size means our confidence in timing advice is limited. Treat this as a price-awareness guide rather than a precise booking calendar.
