Houston → Lima flights

Budget $245 for Houston–Lima, but act fast if fares dip near $215

Key takeaways

• Median fare is $245, based on 18 daily snapshots of the cheapest available fares on this route.
• Bottom-quartile fares sit at $215, meaning roughly 25% of sampled days showed prices at or below that threshold — that's your target.
• Top-quartile prices reach $360, and the single highest recorded fare hit $449 — a 109% spread that signals genuine volatility on this route.
• A 109% spread between low and high is substantial; this route rewards active monitoring rather than booking at any random time.
• Sample size is 18 days — below our preferred 30-day window, so treat these figures as directional guidance rather than settled averages.

The full picture

Houston–Lima fares in this dataset range from $215 to $449, with a median of $245 and a 109% spread between the lowest and highest captured prices. That gap is large enough to matter: a traveler who books at $449 is paying more than twice what the luckiest shopper paid. The interquartile range — $215 to $360 — tells a more practical story. Most days, fares land somewhere in that corridor, which means prices near $245 are genuinely attainable but not guaranteed. Anything at or below $215 should be treated as a floor-level deal worth acting on quickly.

On a route like Houston–Lima, which typically involves one connection and tends to draw a small set of carriers serving the South America corridor, prices can move sharply in response to seat availability changes rather than just calendar patterns. The data here doesn't isolate a clear day-of-week booking pattern — and with 18 samples, any such pattern would be statistically fragile anyway. What the data does support is that fares soften periodically into the $215–$230 range before rebounding; if you see a price in that band, the historical record suggests it won't stay there long.

For planning purposes, budget at the $245 median if you need a reliable anchor for trip cost, and set fare alerts targeting $230 or below. Booking 6–10 weeks ahead tends to capture mid-range fares on long-haul Latin America routes in general industry experience, but nothing in this specific dataset confirms a precise booking window. One honest caveat: with only 18 data points, this analysis captures a snapshot of market conditions, not a full seasonal curve — prices around holidays, northern-hemisphere summer, and Fiestas Patrias in Peru (late July) may behave very differently from what this sample reflects.
