The data shows a route with a low, stable floor and occasional expensive spikes. Most fares — the middle half — sat between $384 and $472, just above the $395 median, which tells us typical pricing is consistent and not wildly volatile day to day. The $838 high is an outlier rather than the norm; it's likely tied to a handful of premium or last-minute fares rather than a broad market shift.
Because 29 of the last 30 days had a cached fare, this is a well-sampled window, and the pattern is clear: the bulk of fares cluster near the low end, with the spread driven by a small number of high-priced days. That 122% spread looks dramatic, but it reflects the gap between the cheapest and most expensive fares seen, not typical day-to-day swings — the p25–p75 band is much narrower and a better guide to what most travelers will actually pay. Booking when fares sit near or below the $395 median, rather than chasing the absolute lowest $377 fare, is a reasonable target given how tightly packed the middle of the distribution is.
We don't have carrier-level detail in this dataset, so we can't say whether the spikes are tied to a specific airline, cabin class, or travel date. The data also doesn't reveal day-of-week patterns, so we can't responsibly recommend specific departure days. The honest takeaway: expect to pay close to $395 most of the time, budget some flexibility in case you land on a pricier day, and treat anything near $800 as an exception worth avoiding by booking ahead rather than waiting.
Why we regenerated this article: Price spread tightened by 63 points. We only rewrite when the underlying price index actually moves — stable weeks keep the previous take.
