The full picture

The data shows a wide band for this route — fares ranged from $184 to $310 over the 30-day sample, a 68% spread that's well above what we'd call a stable market. That kind of range means the difference between a lucky search and an average one can be real money, not noise. The median of $236 is a useful anchor, but it's the quartiles that tell the more actionable story: a quarter of observed fares came in at $190 or below, while the top quarter pushed past $268.

We don't have booking-date-to-departure-date data here, so we can't say definitively when in the horizon prices soften — only that the range itself is wide enough to justify flexible, repeated searching rather than booking at the first price you see. Given the spread, treating anything at or below the $190–$210 range as a good fare, and anything above $270 as worth waiting out, is a reasonable heuristic based purely on where this route's prices have actually clustered.

We don't have reliable carrier-level data for this route, so we can't speak to whether a specific airline consistently undercuts the market or whether nonstop versus connecting itineraries are driving the spread — both are plausible explanations for a 68% range on a long-haul leisure route like this one. The honest caveat: 30 days of snapshots captures recent market behavior but not seasonal swings, so if you're booking for summer peak or holiday travel, treat the $184–$310 range as a starting point rather than a guarantee. Monitor fares over a couple of weeks if you can, and treat anything near the low end of this range as a fare worth taking.
