Houston to Aspen

What the Data Says About IAH to ASE

The Houston to Aspen corridor (IAH → ASE) covers roughly 913 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 3,118 flights in the dataset, this route posts a 68.7% on-time rate with an average delay of 90.4 minutes when flights run late. Over the most recent 24 months of BTS data, 1,478 flights were recorded on this pairing — 71 cancelled (4.8%) and 69 diverted (4.7%). 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 3,118 total flights analyzed, the 68.7% on-time figure is statistically meaningful rather than a small-sample fluke. The 90.4-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 77% on-time, while Mar 2023 came in at 57% on-time — a 20-point gap between best and worst recent month. For travelers evaluating the IAH to ASE route, the combination of a 68.7% on-time rate, 90.4-minute average delay, 4.8% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
