San Antonio to Dallas/Fort Worth

What the Data Says About SAT to DFW

The San Antonio to Dallas/Fort Worth corridor (SAT → DFW) covers roughly 247 miles and is served by 14 carriers, based on Bureau of Transportation Statistics reporting. Across 22,003 flights in the dataset, this route posts a 78.9% on-time rate with an average delay of 92.3 minutes when flights run late. Over the most recent 24 months of BTS data, 9,049 flights were recorded on this pairing — 274 cancelled (3.0%) and 16 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 14 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 22,003 total flights analyzed, the 78.9% on-time figure is statistically meaningful rather than a small-sample fluke. The 92.3-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 84% on-time, while Jul 2024 came in at 64% on-time — a 20-point gap between best and worst recent month. For travelers evaluating the SAT to DFW route, the combination of a 78.9% on-time rate, 92.3-minute average delay, 3.0% recent cancellation rate, and 14 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
