The data shows a $402 median fare for Chicago-to-Dublin flights, but with a notable 71% spread between the $311 low and $531 high, this isn't a route with a single predictable price point. The middle half of observed fares fell between $311 and $430, meaning travelers who see something near or below $350 are likely catching a genuinely good deal relative to the rest of the market, while fares creeping toward $500+ sit well above typical pricing.
With 24 days carrying a fare out of the last 30 in the window, the sample is reasonably solid, though not exhaustive — six days had no cached fare to compare. That gap means some week-to-week variation could be missing from this snapshot. Still, the consistent clustering around the $311–$430 band suggests that patient shoppers who check in regularly over a few weeks have a decent shot at landing in the lower half of that range rather than paying the median or above.
We don't have day-of-week or carrier-specific detail in this dataset, so we can't say whether certain departure days or a dominant airline are driving the cheaper fares — that would require more granular data than what's available here. The honest takeaway is this: expect somewhere in the $350–$430 range as a realistic target, treat anything near $311 as a strong outlier worth jumping on, and don't be surprised if occasional spikes toward $500+ show up, since the wide spread indicates this route can swing significantly even within a single month.
Why we regenerated this article: Median fare ↑ 16% ($346 → $402). We only rewrite when the underlying price index actually moves — stable weeks keep the previous take.
