Houston → Lima flights

Budget $338 for Houston–Lima, but catch lows near $271

Key takeaways

• Median fare is $338 across 11 daily snapshots — a reasonable planning anchor for IAH–LIM roundtrips.
• Bottom-quartile fares reach $271 (p25), suggesting meaningful savings are achievable but not guaranteed.
• The high touched $516, meaning fares can run 90% above the low — an unusually wide spread signaling volatile pricing.
• P75 sits at $482, so at least a quarter of observed fares exceeded that level — avoid booking when prices trend there.
• Sample size is thin (11 days), so treat these figures as directional rather than statistically definitive.

The full picture

Houston–Lima is a mid-haul international route with a striking 90% spread between the lowest observed fare ($271) and the highest ($516). That level of volatility is notable — it tells you this corridor doesn't hold a stable price floor, and timing genuinely matters. The median of $338 is a useful planning number, but the distance between the 25th percentile ($271) and the 75th ($482) — a $211 gap — means the difference between a good deal and an overpayment is real and significant.

On booking timing, routes to Lima from U.S. hubs have historically shown fare softening in the 6–10 week window before departure, as airlines reprice unsold inventory ahead of the final close-in surge. That said, the current dataset spans only 11 days of snapshots, which limits confidence in any precise booking-window recommendation. What the data does support: fares in the bottom quartile ($271–$338) represent materially better value than the upper end, so setting a price alert and acting when fares dip toward that lower band is a sound strategy. Waiting for the absolute floor risks missing a good window entirely.

No dominant carrier pattern is discernible from this dataset, so fare differences likely reflect a mix of routing options (direct vs. one-stop via Bogotá, Mexico City, or Panama City) rather than a single airline's pricing cycle. A non-stop or minimal-connection itinerary will anchor on the higher end; one-stop routings via partner hubs tend to drive the lower fares seen here.

Caveat: with only 11 data points, these figures should be treated as early indicators rather than firm benchmarks. Continue monitoring fares over a wider window before drawing firm conclusions about typical price behavior on this route.
