Bottom quartile ($321) equals the floor, meaning a meaningful share of snapshots hit the best observed price.

The full picture

The data shows a notably narrow band for Chicago to Athens fares: a median of $321, a low of $321, and a high of $365, for a spread of just 14%. That's a tight range by international long-haul standards, suggesting that whatever is driving pricing on this route — capacity, competition, or seasonality — hasn't shifted much over the 12-day sample window. When spread is this small, chasing a 'perfect' booking day matters less than it might on a more volatile route; the difference between a lucky and unlucky day is roughly $44.

We don't have enough historical depth here to say definitively when in the booking horizon prices soften, since we're working with 12 snapshots rather than a full seasonal cycle. What we can say is that the bottom quartile ($321) matches the observed floor, meaning fares at or near the cheapest price weren't rare outliers — they showed up often enough to anchor the 25th percentile. That's a reasonably good sign for travelers: booking whenever convenient, within a normal planning window of a few weeks to a couple months out, is unlikely to cost you much more than booking on a 'perfect' day.

We don't have visibility into a dominant carrier or specific day-of-week effects in this dataset, so we can't make claims about airline-specific pricing behavior or whether midweek departures are cheaper here. The honest caveat: with only 12 days of snapshots, this read is a short-term snapshot rather than a seasonal trend — fares could shift meaningfully as we move into a different booking season or closer to peak summer travel to Greece. Treat $321–$365 as a working range for now, and re-check closer to your travel dates if they fall outside the near-term window this data covers.
