Houston to Amarillo

What the Data Says About IAH to AMA

The Houston to Amarillo corridor (IAH → AMA) covers roughly 517 miles and is served by 2 carriers, based on Bureau of Transportation Statistics reporting. Across 1,970 flights in the dataset, this route posts a 79.9% on-time rate with an average delay of 103.3 minutes when flights run late. Over the most recent 24 months of BTS data, 1,243 flights were recorded on this pairing — 16 cancelled (1.3%) and 5 diverted (0.4%). Those baseline metrics tell you what to expect before you book.

Having 2 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 1,970 total flights analyzed, the 79.9% on-time figure is statistically meaningful rather than a small-sample fluke. The 103.3-minute average delay applies only to flights that actually ran late, so it is not the average wait across all departures — the majority of flights on this route depart on time under the BTS definition of a delay (15+ minutes past schedule).

Looking at recent months, Sep 2021 posted the best performance on this corridor at 90% on-time, while Mar 2023 came in at 63% on-time — a 27-point gap between best and worst recent month. For travelers evaluating the IAH to AMA route, the combination of a 79.9% on-time rate, 103.3-minute average delay, 1.3% recent cancellation rate, and 2 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
