What the Data Says About HOU to BNA

The Houston to Nashville corridor (HOU → BNA) covers roughly 670 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 9,215 flights in the dataset, this route posts a 82.4% on-time rate with an average delay of 56.3 minutes when flights run late. Over the most recent 24 months of BTS data, 3,547 flights were recorded on this pairing — 32 cancelled (0.9%) and 8 diverted (0.2%). 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 9,215 total flights analyzed, the 82.4% on-time figure is statistically meaningful rather than a small-sample fluke. The 56.3-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, Jan 2025 posted the best performance on this corridor at 92% on-time, while May 2024 came in at 68% on-time — a 24-point gap between best and worst recent month. For travelers evaluating the HOU to BNA route, the combination of a 82.4% on-time rate, 56.3-minute average delay, 0.9% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
