Denver to Anchorage

What the Data Says About DEN to ANC

The Denver to Anchorage corridor (DEN → ANC) covers roughly 2,405 miles and is served by 5 carriers, based on Bureau of Transportation Statistics reporting. Across 2,955 flights in the dataset, this route posts a 76% on-time rate with an average delay of 59.0 minutes when flights run late. Over the most recent 24 months of BTS data, 1,222 flights were recorded on this pairing — 4 cancelled (0.3%) and 12 diverted (1.0%). 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 2,955 total flights analyzed, the 76% on-time figure is statistically meaningful rather than a small-sample fluke. The 59.0-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 2024 posted the best performance on this corridor at 84% on-time, while Jul 2025 came in at 66% on-time — a 18-point gap between best and worst recent month. For travelers evaluating the DEN to ANC route, the combination of a 76% on-time rate, 59.0-minute average delay, 0.3% recent cancellation rate, and 5 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
