Anchorage to Juneau

What the Data Says About ANC to JNU

The Anchorage to Juneau corridor (ANC → JNU) covers roughly 571 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 6,787 flights in the dataset, this route posts a 85% on-time rate with an average delay of 55.7 minutes when flights run late. Over the most recent 24 months of BTS data, 2,445 flights were recorded on this pairing — 8 cancelled (0.3%) and 16 diverted (0.7%). 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 6,787 total flights analyzed, the 85% on-time figure is statistically meaningful rather than a small-sample fluke. The 55.7-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, Oct 2025 posted the best performance on this corridor at 94% on-time, while Jan 2024 came in at 71% on-time — a 22-point gap between best and worst recent month. For travelers evaluating the ANC to JNU route, the combination of a 85% on-time rate, 55.7-minute average delay, 0.3% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
