Amarillo to Houston

What the Data Says About AMA to IAH

The Amarillo to Houston corridor (AMA → IAH) covers roughly 517 miles and is served by 3 carriers, based on Bureau of Transportation Statistics reporting. Across 1,999 flights in the dataset, this route posts a 83.4% on-time rate with an average delay of 113.6 minutes when flights run late. Over the most recent 24 months of BTS data, 1,273 flights were recorded on this pairing — 19 cancelled (1.5%) and 2 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 3 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 1,999 total flights analyzed, the 83.4% on-time figure is statistically meaningful rather than a small-sample fluke. The 113.6-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 2022 posted the best performance on this corridor at 95% on-time, while Apr 2025 came in at 73% on-time — a 21-point gap between best and worst recent month. For travelers evaluating the AMA to IAH route, the combination of a 83.4% on-time rate, 113.6-minute average delay, 1.5% recent cancellation rate, and 3 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
