San Francisco to Missoula

What the Data Says About SFO to MSO

The San Francisco to Missoula corridor (SFO → MSO) covers roughly 769 miles and is served by 2 carriers, based on Bureau of Transportation Statistics reporting. Across 522 flights in the dataset, this route posts a 82.2% on-time rate with an average delay of 62.2 minutes when flights run late. Over the most recent 24 months of BTS data, 522 flights were recorded on this pairing — 0 cancelled (0.0%) and 1 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 2 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 522 total flights analyzed, the 82.2% on-time figure is statistically meaningful rather than a small-sample fluke. The 62.2-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 SFO to MSO route, the combination of a 82.2% on-time rate, 62.2-minute average delay, 0.0% recent cancellation rate, and 2 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
