The full picture

Fares on the Houston (IAH) to Rio de Janeiro (GIG) route show a meaningful but not extreme price range. With a low of $338 and a high of $443 across 30 days of data, the spread of 31% is large enough to reward patience and planning. The median of $365 is a reliable anchor: fares above $400 represent the pricier quartile of what this route typically offers, and shoppers who find themselves quoted $424 or more are likely looking at a less competitive moment in the inventory cycle.

On a long-haul international route like IAH–GIG — roughly 10 hours nonstop — fares tend to soften when purchased in the 4-to-8-week window before departure, before last-minute demand from business and leisure travelers tightens availability. That said, this dataset captures fare snapshots rather than a booking-horizon curve, so treat that window as a general heuristic rather than a hard rule. What the data does confirm is that fares cluster tightly in the $338–$365 zone for the bottom quarter of observations, meaning deals at or near the low end are not rare anomalies — they appear with enough regularity to be a realistic target.

No single dominant carrier emerged from the cheapest-fare data, which is a useful signal: this route appears to have competitive pricing from more than one airline, so comparing across carriers before purchasing is a practical step rather than just a platitude. One honest caveat: 30 snapshots give a solid baseline, but they reflect a specific window in time. Seasonal demand shifts — particularly around Carnival, Brazilian school holidays, and Northern Hemisphere summer — can push fares well outside this range in either direction. If your travel falls near those peaks, the $443 high in this dataset may actually look attractive by comparison.
