Dallas/Fort Worth to Chattanooga

What the Data Says About DFW to CHA

The Dallas/Fort Worth to Chattanooga corridor (DFW → CHA) covers roughly 695 miles and is served by 8 carriers, based on Bureau of Transportation Statistics reporting. Across 6,834 flights in the dataset, this route posts a 82.4% on-time rate with an average delay of 70.7 minutes when flights run late. Over the most recent 24 months of BTS data, 3,049 flights were recorded on this pairing — 58 cancelled (1.9%) and 4 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 8 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 6,834 total flights analyzed, the 82.4% on-time figure is statistically meaningful rather than a small-sample fluke. The 70.7-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, Oct 2024 posted the best performance on this corridor at 92% on-time, while Jun 2025 came in at 61% on-time — a 31-point gap between best and worst recent month. For travelers evaluating the DFW to CHA route, the combination of a 82.4% on-time rate, 70.7-minute average delay, 1.9% recent cancellation rate, and 8 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
