Sitka to Juneau

What the Data Says About SIT to JNU

The Sitka to Juneau corridor (SIT → JNU) covers roughly 95 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 3,876 flights in the dataset, this route posts a 86.1% on-time rate with an average delay of 64.4 minutes when flights run late. Over the most recent 24 months of BTS data, 1,454 flights were recorded on this pairing — 27 cancelled (1.9%) and 17 diverted (1.2%). 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 3,876 total flights analyzed, the 86.1% on-time figure is statistically meaningful rather than a small-sample fluke. The 64.4-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, Sep 2024 posted the best performance on this corridor at 93% on-time, while Dec 2025 came in at 71% on-time — a 22-point gap between best and worst recent month. For travelers evaluating the SIT to JNU route, the combination of a 86.1% on-time rate, 64.4-minute average delay, 1.9% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
