Aspen to Dallas/Fort Worth

What the Data Says About ASE to DFW

The Aspen to Dallas/Fort Worth corridor (ASE → DFW) covers roughly 701 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 5,987 flights in the dataset, this route posts a 69.6% on-time rate with an average delay of 110.9 minutes when flights run late. Over the most recent 24 months of BTS data, 2,472 flights were recorded on this pairing — 171 cancelled (6.9%) and 20 diverted (0.8%). 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 5,987 total flights analyzed, the 69.6% on-time figure is statistically meaningful rather than a small-sample fluke. The 110.9-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 Jun 2025 came in at 59% on-time — a 36-point gap between best and worst recent month. For travelers evaluating the ASE to DFW route, the combination of a 69.6% on-time rate, 110.9-minute average delay, 6.9% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
