Houston → Lima flights

Budget $259 for Houston–Lima, but watch for $516 spikes

Key takeaways

• Median fare is $259, with the middle 50% of daily snapshots falling in a tight $254–$273 band.
• The low end is $250 — just $9 below median — suggesting floor prices are fairly accessible most of the time.
• High-end fares hit $516, more than double the median, pointing to occasional demand or inventory surges worth avoiding.
• Spread of 106% is driven almost entirely by those upper outliers; the interquartile range is a narrow $19, so 'normal' pricing is remarkably stable.
• No dominant carrier was identifiable in this dataset, so comparison-shopping across airlines is especially worthwhile on this route.

The full picture

The Houston (IAH) to Lima (LIM) route shows a strikingly compressed everyday price band: the 25th-to-75th-percentile range spans just $254 to $273, a $19 window that accounts for the bulk of observed fares across 30 daily snapshots. That kind of tightness usually signals a competitive route where a small number of carriers are actively matching each other near a price floor. For most travelers, the realistic target is $259 or below — and the data suggests that's achievable on the majority of shopping days.

The outlier story is the more important planning signal. A high of $516 — more than double the median — inflates the overall spread to 106%, but that figure is misleading if taken at face value. Those spikes appear to reflect isolated demand windows or reduced inventory rather than a systematic pricing pattern. The practical implication: if you're seeing fares above $300 during a search, the data suggests you're outside the normal range and may benefit from checking back over the following few days rather than booking immediately. Conversely, fares near $250 represent genuine bottom-quartile pricing and are worth locking in.

Because no single dominant carrier emerged from this dataset, it's worth running searches across multiple booking tools on this route — price parity is not guaranteed, and a few dollars of variation between platforms is common. There is no evidence in this data to support day-of-week booking rules for IAH–LIM; that kind of pattern would require fare-calendar data not present here. One honest caveat: 30 snapshots capture roughly one calendar month of pricing, so seasonal shifts — particularly around South American summer (December–February) or major Peruvian holidays — could push fares well outside this observed range.
