Juneau to Sitka

What the Data Says About JNU to SIT

The Juneau to Sitka corridor (JNU → SIT) 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 83.8% on-time rate with an average delay of 55.1 minutes when flights run late. Over the most recent 24 months of BTS data, 1,454 flights were recorded on this pairing — 26 cancelled (1.8%) and 6 diverted (0.4%). 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 83.8% on-time figure is statistically meaningful rather than a small-sample fluke. The 55.1-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 97% on-time, while Jan 2024 came in at 67% on-time — a 30-point gap between best and worst recent month. For travelers evaluating the JNU to SIT route, the combination of a 83.8% on-time rate, 55.1-minute average delay, 1.8% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
