What the Data Says About IAH to ABI

The Houston to Abilene corridor (IAH → ABI) covers roughly 307 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 528 flights in the dataset, this route posts a 88.4% on-time rate with an average delay of 145.9 minutes when flights run late. Over the most recent 24 months of BTS data, 528 flights were recorded on this pairing — 9 cancelled (1.7%) and 0 diverted (0.0%). Those baseline metrics tell you what to expect before you book.

Having 1 carrier on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 528 total flights analyzed, the 88.4% on-time figure is statistically meaningful rather than a small-sample fluke. The 145.9-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, Dec 2020 posted the best performance on this corridor at 97% on-time, while Jun 2021 came in at 76% on-time — a 21-point gap between best and worst recent month. For travelers evaluating the IAH to ABI route, the combination of a 88.4% on-time rate, 145.9-minute average delay, 1.7% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
