The full picture
Over 25 daily snapshots, Miami to Santiago fares showed a median of $267, with the bulk of prices — the middle 50% — clustered tightly between $221 and $282. That's a narrow, predictable range for most shopping windows. The headline spread of 133%, however, is driven almost entirely by a small number of high-end outliers reaching as much as $516, rather than by the typical fare drifting upward. In practice, this means travelers who see something in the low-to-mid $200s are looking at a normal, well-priced fare, while anything approaching $400 or beyond is an outlier worth passing on or waiting out.
With only 25 data points, we can't make sharp claims about exactly which week or month within the booking horizon tends to soften — the sample isn't dense enough to isolate that pattern reliably. What the data does support is a general strategy: since 75% of observed fares were $282 or below, that figure is a useful ceiling to shop against. If you're quoted meaningfully more than that, it's reasonable to wait a few days and check again, since the data suggests the market frequently returns to the $221–$282 band.
We don't have visibility into a dominant carrier for this route in the current dataset, so we can't speak to airline-specific pricing behavior or whether particular carriers are driving the high-end outliers. The honest caveat here is that a 133% spread on a 25-day sample is large enough that a handful of unusual fares (last-minute business fares, premium cabin mixes, or holiday-adjacent pricing) could be skewing the high end without reflecting what most travelers will actually pay. Treat the median and interquartile range as your primary guide, and treat the $516 high as a signal of what to avoid rather than what to expect.
