Dallas/Fort Worth to Birmingham

What the Data Says About DFW to BHM

The Dallas/Fort Worth to Birmingham corridor (DFW → BHM) covers roughly 597 miles and is served by 40 carriers, based on Bureau of Transportation Statistics reporting. Across 11,643 flights in the dataset, this route posts a 76.1% on-time rate with an average delay of 79.6 minutes when flights run late. Over the most recent 24 months of BTS data, 4,604 flights were recorded on this pairing — 104 cancelled (2.3%) and 5 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 40 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 11,643 total flights analyzed, the 76.1% on-time figure is statistically meaningful rather than a small-sample fluke. The 79.6-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, Oct 2024 posted the best performance on this corridor at 88% on-time, while Jun 2025 came in at 62% on-time — a 26-point gap between best and worst recent month. For travelers evaluating the DFW to BHM route, the combination of a 76.1% on-time rate, 79.6-minute average delay, 2.3% recent cancellation rate, and 40 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
