Columbus to Dallas/Fort Worth

What the Data Says About CMH to DFW

The Columbus to Dallas/Fort Worth corridor (CMH → DFW) covers roughly 926 miles and is served by 9 carriers, based on Bureau of Transportation Statistics reporting. Across 9,144 flights in the dataset, this route posts a 81.8% on-time rate with an average delay of 104.1 minutes when flights run late. Over the most recent 24 months of BTS data, 3,467 flights were recorded on this pairing — 75 cancelled (2.2%) and 18 diverted (0.5%). Those baseline metrics tell you what to expect before you book.

Having 9 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 9,144 total flights analyzed, the 81.8% on-time figure is statistically meaningful rather than a small-sample fluke. The 104.1-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 May 2025 came in at 69% on-time — a 22-point gap between best and worst recent month. For travelers evaluating the CMH to DFW route, the combination of a 81.8% on-time rate, 104.1-minute average delay, 2.2% recent cancellation rate, and 9 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
