Louisville to Dallas/Fort Worth

What the Data Says About SDF to DFW

The Louisville to Dallas/Fort Worth corridor (SDF → DFW) covers roughly 733 miles and is served by 28 carriers, based on Bureau of Transportation Statistics reporting. Across 11,294 flights in the dataset, this route posts a 78.2% on-time rate with an average delay of 103.1 minutes when flights run late. Over the most recent 24 months of BTS data, 4,248 flights were recorded on this pairing — 116 cancelled (2.7%) and 16 diverted (0.4%). Those baseline metrics tell you what to expect before you book.

Having 28 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 11,294 total flights analyzed, the 78.2% on-time figure is statistically meaningful rather than a small-sample fluke. The 103.1-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 89% on-time, while May 2024 came in at 60% on-time — a 29-point gap between best and worst recent month. For travelers evaluating the SDF to DFW route, the combination of a 78.2% on-time rate, 103.1-minute average delay, 2.7% recent cancellation rate, and 28 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
