Or LAX-OAK. In the summers when the fog and low clouds roll into SFO gets problematic for all airlines, fast. I did that commuter route weekly for years on United, Southwest, American, and Delta. With the exception of United post-merger, the routes were generally visibility issues.

Only real option is to be able to get put on an earlier flight that's been delayed to your original departure time or reroute to OAK or SJC (co-terminals).
