What the Data Says About MRY to SFO

The Monterey to San Francisco corridor (MRY → SFO) covers roughly 77 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 2,728 flights in the dataset, this route posts a 83.9% on-time rate with an average delay of 86.8 minutes when flights run late.

Having 1 carrier on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 2,728 total flights analyzed, the 83.9% on-time figure is statistically meaningful rather than a small-sample fluke. The 86.8-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, Aug 2025 posted the best performance on this corridor at 91% on-time, while Sep 2024 came in at 60% on-time — a 31-point gap between best and worst recent month. For travelers evaluating the MRY to SFO route, the combination of a 83.9% on-time rate, 86.8-minute average delay, 1.2% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
