Dallas/Fort Worth to South Bend

What the Data Says About DFW to SBN

The Dallas/Fort Worth to South Bend corridor (DFW → SBN) covers roughly 846 miles and is served by 4 carriers, based on Bureau of Transportation Statistics reporting. Across 5,031 flights in the dataset, this route posts a 79.7% on-time rate with an average delay of 78.7 minutes when flights run late. Over the most recent 24 months of BTS data, 1,946 flights were recorded on this pairing — 32 cancelled (1.6%) and 7 diverted (0.4%). Those baseline metrics tell you what to expect before you book.

Having 4 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 5,031 total flights analyzed, the 79.7% on-time figure is statistically meaningful rather than a small-sample fluke. The 78.7-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 2024 posted the best performance on this corridor at 89% on-time, while Jun 2025 came in at 67% on-time — a 22-point gap between best and worst recent month. For travelers evaluating the DFW to SBN route, the combination of a 79.7% on-time rate, 78.7-minute average delay, 1.6% recent cancellation rate, and 4 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
