What the Data Says About JAN to IAH

The Jackson/Vicksburg to Houston corridor (JAN → IAH) covers roughly 351 miles and is served by 7 carriers, based on Bureau of Transportation Statistics reporting. Across 990 flights in the dataset, this route posts a 89.2% on-time rate with an average delay of 81.7 minutes when flights run late. Over the most recent 24 months of BTS data, 990 flights were recorded on this pairing — 52 cancelled (5.3%) and 3 diverted (0.3%). 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 990 total flights analyzed, the 89.2% on-time figure is statistically meaningful rather than a small-sample fluke. The 81.7-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, Aug 2020 posted the best performance on this corridor at 94% on-time, while Jan 2020 came in at 86% on-time — a 8-point gap between best and worst recent month. For travelers evaluating the JAN to IAH route, the combination of a 89.2% on-time rate, 81.7-minute average delay, 5.3% recent cancellation rate, and 7 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
