What the Data Says About SUN to SFO

The Sun Valley/Hailey/Ketchum to San Francisco corridor (SUN → SFO) covers roughly 587 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 704 flights in the dataset, this route posts a 71.4% on-time rate with an average delay of 92.2 minutes when flights run late. Over the most recent 24 months of BTS data, 704 flights were recorded on this pairing — 19 cancelled (2.7%) and 1 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 704 total flights analyzed, the 71.4% on-time figure is statistically meaningful rather than a small-sample fluke. The 92.2-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).

Monthly performance varies, so review the monthly table above to see specific periods. For travelers evaluating the SUN to SFO route, the combination of a 71.4% on-time rate, 92.2-minute average delay, 2.7% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
