Houston to Mobile

What the Data Says About IAH to MOB

The Houston to Mobile corridor (IAH → MOB) covers roughly 427 miles and is served by 7 carriers, based on Bureau of Transportation Statistics reporting. Across 1,390 flights in the dataset, this route posts a 87.6% on-time rate with an average delay of 85.3 minutes when flights run late. Over the most recent 24 months of BTS data, 1,390 flights were recorded on this pairing — 85 cancelled (6.1%) and 5 diverted (0.4%). Those baseline metrics tell you what to expect before you book.

Having 7 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 1,390 total flights analyzed, the 87.6% on-time figure is statistically meaningful rather than a small-sample fluke. The 85.3-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, Apr 2020 posted the best performance on this corridor at 100% on-time, while Aug 2021 came in at 79% on-time — a 21-point gap between best and worst recent month. For travelers evaluating the IAH to MOB route, the combination of a 87.6% on-time rate, 85.3-minute average delay, 6.1% recent cancellation rate, and 7 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
