And depending on how one is getting to SFO and from where ... I'm usually in a car and it takes 25 minutes to the terminal from my home across the Bay Bridge before 5am. After, I need to add an hour of cushion just to be sure I'll probably make it.
One thing about SFO, they have cancelled a slew of flights either the first morning or last afternoon flight on this route all month, so I wouldn't even consider first flight from SFO safe as any weather/ATC management on the east coast/JFK SFO is one of the first routes axed.
