Dallas/Fort Worth to Aspen

What the Data Says About DFW to ASE

The Dallas/Fort Worth to Aspen corridor (DFW → ASE) covers roughly 701 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 5,988 flights in the dataset, this route posts a 74.8% on-time rate with an average delay of 72.9 minutes when flights run late. Over the most recent 24 months of BTS data, 2,472 flights were recorded on this pairing — 72 cancelled (2.9%) and 144 diverted (5.8%). Those baseline metrics tell you what to expect before you book.

Having 1 carrier on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 5,988 total flights analyzed, the 74.8% on-time figure is statistically meaningful rather than a small-sample fluke. The 72.9-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, Nov 2023 posted the best performance on this corridor at 95% on-time, while Dec 2025 came in at 57% on-time — a 38-point gap between best and worst recent month. For travelers evaluating the DFW to ASE route, the combination of a 74.8% on-time rate, 72.9-minute average delay, 2.9% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
