The full picture

The data shows a moderate spread on this route: fares ranged from $393 to $484 over 23 days of snapshots, a 23% swing from low to high. That's enough variability to reward some price-watching, but not so wide that timing becomes the dominant factor in what you pay. Half of the observed fares clustered between $393 and $430 (the p25–p75 range), which is a reasonable target band if you're deciding whether a quoted price is competitive.

With only 23 daily snapshots, we can't make confident claims about how prices move across a full booking horizon — this data doesn't tell us whether fares are cheaper 60 days out versus 2 weeks out. What it does tell us is the current pricing landscape: if you see something near or below $400, that's in the bottom quartile of what this route has shown recently, and it's a reasonable signal to book rather than wait. Fares creeping toward $450-$484 land in the upper range and may be worth comparing against alternate dates if your travel is flexible.

We don't have visibility into a dominant carrier or day-of-week patterns from this dataset, so we can't speak to whether specific airlines or departure days consistently price lower on this route. The honest caveat here: 23 days is a decent sample but still a snapshot in time, not a seasonal trend — prices on IAH–GIG could shift with demand changes, fuel costs, or schedule updates that this window doesn't capture. Use the $393–$430 range as a practical benchmark, but don't treat it as a guarantee of future pricing.
