The full picture
Fares between Chicago and Lima have been remarkably stable over the window we tracked, with a median of $387 and a high that also tops out at $387 — meaning most days actually priced at or near the ceiling. The real opportunity sits in the bottom quartile, where fares dropped to $375 and, on the best day observed, $340. That's a 14% spread between low and high, which counts as tight: this isn't a route where patient travelers get rewarded with dramatic savings by waiting.
Because the spread is small, we can't point to a clear 'book early vs. book late' pattern with confidence — the data doesn't show prices softening or hardening at a particular point in a booking horizon. What we can say is that if you see a fare at or below the $375 p25 mark, that's already a good price relative to this route's recent history, and waiting for something meaningfully cheaper than $340 isn't supported by what we've observed. Booking whenever your travel dates firm up is a reasonable strategy here, since the downside risk of 'bad timing' is modest compared to routes with wider swings.
We didn't see a usable carrier or day-of-week signal in this dataset — fares didn't cluster in a way that pointed to a dominant airline or a consistently cheaper departure day. The honest caveat: with only 12 snapshots, this is a thinner sample than we'd like, and seasonal demand (holiday travel, Peru's high season) could shift this range in ways a 30-day window won't capture. Treat the $340–$387 band as a reliable near-term guide, not a long-term guarantee.
