What the Data Says About JNU to ANC

The Juneau to Anchorage corridor (JNU → ANC) covers roughly 571 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 6,699 flights in the dataset, this route posts a 84.8% on-time rate with an average delay of 73.5 minutes when flights run late. Over the most recent 24 months of BTS data, 2,446 flights were recorded on this pairing — 52 cancelled (2.1%) and 2 diverted (0.1%). 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 6,699 total flights analyzed, the 84.8% on-time figure is statistically meaningful rather than a small-sample fluke. The 73.5-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, Feb 2025 posted the best performance on this corridor at 96% on-time, while Dec 2025 came in at 66% on-time — a 30-point gap between best and worst recent month. For travelers evaluating the JNU to ANC route, the combination of a 84.8% on-time rate, 73.5-minute average delay, 2.1% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
