Denver to Dallas/Fort Worth

What the Data Says About DEN to DFW

The Denver to Dallas/Fort Worth corridor (DEN → DFW) covers roughly 641 miles and is served by 25 carriers, based on Bureau of Transportation Statistics reporting. Across 33,523 flights in the dataset, this route posts a 77.5% on-time rate with an average delay of 83.0 minutes when flights run late. Over the most recent 24 months of BTS data, 12,238 flights were recorded on this pairing — 242 cancelled (2.0%) and 45 diverted (0.4%). Those baseline metrics tell you what to expect before you book.

Having 25 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 33,523 total flights analyzed, the 77.5% on-time figure is statistically meaningful rather than a small-sample fluke. The 83.0-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 86% on-time, while Jun 2025 came in at 63% on-time — a 23-point gap between best and worst recent month. For travelers evaluating the DEN to DFW route, the combination of a 77.5% on-time rate, 83.0-minute average delay, 2.0% recent cancellation rate, and 25 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
