Dallas/Fort Worth to Bismarck/Mandan

What the Data Says About DFW to BIS

The Dallas/Fort Worth to Bismarck/Mandan corridor (DFW → BIS) covers roughly 977 miles and is served by 7 carriers, based on Bureau of Transportation Statistics reporting. Across 3,727 flights in the dataset, this route posts a 80.2% on-time rate with an average delay of 66.4 minutes when flights run late. Over the most recent 24 months of BTS data, 1,333 flights were recorded on this pairing — 7 cancelled (0.5%) and 1 diverted (0.1%). 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 3,727 total flights analyzed, the 80.2% on-time figure is statistically meaningful rather than a small-sample fluke. The 66.4-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 92% on-time, while Jun 2025 came in at 62% on-time — a 30-point gap between best and worst recent month. For travelers evaluating the DFW to BIS route, the combination of a 80.2% on-time rate, 66.4-minute average delay, 0.5% recent cancellation rate, and 7 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
