Anchorage to Denver

What the Data Says About ANC to DEN

The Anchorage to Denver corridor (ANC → DEN) covers roughly 2,405 miles and is served by 5 carriers, based on Bureau of Transportation Statistics reporting. Across 2,952 flights in the dataset, this route posts a 82.8% on-time rate with an average delay of 84.3 minutes when flights run late. Over the most recent 24 months of BTS data, 1,219 flights were recorded on this pairing — 7 cancelled (0.6%) and 1 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 5 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 2,952 total flights analyzed, the 82.8% on-time figure is statistically meaningful rather than a small-sample fluke. The 84.3-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, Jun 2025 posted the best performance on this corridor at 91% on-time, while Aug 2025 came in at 83% on-time — a 8-point gap between best and worst recent month. For travelers evaluating the ANC to DEN route, the combination of a 82.8% on-time rate, 84.3-minute average delay, 0.6% recent cancellation rate, and 5 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
