Houston → Lima flights

Target $256–$290 for Houston–Lima; avoid the $400+ spikes

Key takeaways

• Median fare is $290, based on 30 daily snapshots of the cheapest available cached fares on this route.
• Bottom-quartile fares fall at or below $256 — that's your realistic target if you have flexibility to wait or compare.
• The low recorded was $237, but the high hit $467 — a 97% spread signals this route prices very erratically.
• The middle 50% of fares landed between $256 and $328, meaning most shoppers who weren't unlucky paid under $330.
• Spikes above $400 do occur — likely around peak travel periods or thin inventory windows — so locking in near median is a safer move than waiting for a deeper deal.

The full picture

The Houston (IAH) to Lima (LIM) route shows a wide and volatile price distribution. With a spread of 97% between the lowest and highest observed fares — $237 to $467 — this is not a route where you can expect stable, predictable pricing. The median of $290 and the interquartile range of $256–$328 tell a more useful story: if you shop at a reasonable point in the booking window, paying somewhere in the $260–$310 range is achievable and realistic. Fares at or below the $256 p25 mark represent genuine value and are worth acting on quickly when you see them.

On routes with this level of price volatility, booking too early or too late both carry risk. Fares tend to soften in the 6–10 week window before departure as airlines fill base inventory, then firm up again in the final 2–3 weeks as remaining seats get scarcer and more expensive. Given that the top quartile on this route starts at $328 and the high reached $467, there's real downside to procrastinating. If you spot a fare at or below the $290 median, that's a credible signal to book rather than hold out.

No dominant carrier pattern is visible from this dataset, so it's worth checking both legacy carriers and any low-cost operators serving the route on a given search day — price differences between carriers can be significant on South American routes. One honest caveat: 30 daily snapshots capture a single rolling window and may not reflect seasonal demand shifts, such as holiday travel around Christmas or Fiestas Patrias in late July, when fares on this corridor have historically tightened. If your travel falls near those periods, weight your expectations toward the upper end of the observed range.
