Denver to Austin

What the Data Says About DEN to AUS

The Denver to Austin corridor (DEN → AUS) covers roughly 775 miles and is served by 29 carriers, based on Bureau of Transportation Statistics reporting. Across 25,122 flights in the dataset, this route posts a 78% on-time rate with an average delay of 61.8 minutes when flights run late. Over the most recent 24 months of BTS data, 9,549 flights were recorded on this pairing — 59 cancelled (0.6%) and 23 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 29 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 25,122 total flights analyzed, the 78% on-time figure is statistically meaningful rather than a small-sample fluke. The 61.8-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, Sep 2024 posted the best performance on this corridor at 88% on-time, while Jul 2025 came in at 58% on-time — a 30-point gap between best and worst recent month. For travelers evaluating the DEN to AUS route, the combination of a 78% on-time rate, 61.8-minute average delay, 0.6% recent cancellation rate, and 29 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
