ASE delay-share reading

The standout signal at Aspen, CO is on-time standing: 73.5% (5.5 pts below the 79% national flight-weighted average; roughly the bottom-quartile on-time performance) across 78,805 BTS flights (2020–2025). When a departure runs late, the average delay is 97.1 minutes; cancellations run 3.88%.

Delay minutes concentrate in Carrier (28.5% late-aircraft, 34.7% carrier, 15.0% NAS, 21.4% weather, 0.4% security). As a busy airport, that mix matters more for connection planning than for a thin schedule.

On the multi-year calendar, ASE is strongest in November (92.5% on-time) and weakest in December (82%), a 10.5-point swing. Volume peaks in March (~1,889 flights/month). The busiest connecting route is to DEN (Denver) at 74.9% on-time. Field definitions: on-time performance explained.

Using ASE's data

ASE's on-time book sits in the slower half of the BTS set; check the delay mix and the worst month before treating the headline as typical.

  • Check the busiest route from ASE before you book a connection. See top routes
  • Travel in November rather than December if your dates are flexible. Seasonal patterns
  • Build extra connection buffer when taxi-out spikes. March 2024 averaged 26.1 min. Taxi times

On-time rate reflects the BTS historical average across all reporting carriers at this airport, not any single flight or airline.
