Aspen to Houston

What the Data Says About ASE to IAH

The Aspen to Houston corridor (ASE → IAH) covers roughly 913 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 3,122 flights in the dataset, this route posts a 69% on-time rate with an average delay of 99.6 minutes when flights run late. Over the most recent 24 months of BTS data, 1,482 flights were recorded on this pairing — 96 cancelled (6.5%) and 14 diverted (0.9%). 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 3,122 total flights analyzed, the 69% on-time figure is statistically meaningful rather than a small-sample fluke. The 99.6-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, Aug 2023 posted the best performance on this corridor at 76% on-time, while Dec 2024 came in at 51% on-time — a 24-point gap between best and worst recent month. For travelers evaluating the ASE to IAH route, the combination of a 69% on-time rate, 99.6-minute average delay, 6.5% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
