Houston → Lima flights

Houston–Lima fares cluster near $261 — act when you see $252

Key takeaways

• Median fare is $261, based on 30 daily snapshots of the cheapest cached fares on this route.
• Bottom 25% of fares came in at $252 or below — that $9 gap from median is a credible, if modest, target to chase.
• The floor was $250 and the ceiling $321, a spread of roughly 28% — wide enough to matter, so timing your purchase is worth the effort.
• Top-quartile fares crossed $273, meaning roughly one-in-four snapshots showed prices noticeably above median — don't assume low prices will persist.
• A 28% spread suggests meaningful price variation on this route; fares are not locked in and can move by $60–70 from their cheapest to most expensive observed points.

The full picture

Houston to Lima is a competitive South American corridor, and the 30-day snapshot data reflects that: a $261 median with a floor of $250 and a ceiling of $321 tells you fares are generally accessible but not immovable. The 28% spread — roughly $71 from low to high — is meaningful enough that watching the market for a few days before committing can realistically save you $20–60. The interquartile range ($252–$273) is the most useful anchor here: fares spend the bulk of their time in that $21 band, so anything at or below $252 is a genuine bottom-quartile opportunity worth acting on quickly.

On booking horizon, the data doesn't pinpoint an exact advance-purchase sweet spot, but a spread of this size on a long-haul international route typically reflects inventory management by carriers rather than random noise. Prices on routes like IAH–LIM tend to firm up as the departure window tightens and premium-class seats fill, which historically pushes economy fares upward. A reasonable working assumption is that fares seen in the $250–$255 range are closer to the floor than the ceiling and unlikely to drop materially further — making them worth locking in rather than waiting out.

Day-of-week booking or departure patterns are not directly visible in this dataset, so no credible claim can be made about whether Tuesday departures or midweek searches yield better results on this specific route. One honest caveat: 30 snapshots capture a single rolling window and may not reflect seasonal surges — school holidays, Peruvian national holidays, or peak northern-hemisphere summer travel can push fares well above the $321 high observed here. If your travel falls near any of those periods, treat the figures above as off-peak baselines rather than universal guarantees.
