Anchorage to Dillingham

What the Data Says About ANC to DLG

The Anchorage to Dillingham corridor (ANC → DLG) covers roughly 329 miles and is served by 4 carriers, based on Bureau of Transportation Statistics reporting. Across 1,089 flights in the dataset, this route posts a 86.2% on-time rate with an average delay of 54.0 minutes when flights run late. Over the most recent 24 months of BTS data, 862 flights were recorded on this pairing — 48 cancelled (5.6%) and 7 diverted (0.8%). Those baseline metrics tell you what to expect before you book.

Having 4 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 1,089 total flights analyzed, the 86.2% on-time figure is statistically meaningful rather than a small-sample fluke. The 54.0-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 2021 posted the best performance on this corridor at 95% on-time, while Aug 2022 came in at 85% on-time — a 10-point gap between best and worst recent month. For travelers evaluating the ANC to DLG route, the combination of a 86.2% on-time rate, 54.0-minute average delay, 5.6% recent cancellation rate, and 4 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
