Funny. I would not fly for a trip of 350 miles. Being at the airport early, going through security, checking in luggage, all of those are unpredictable. Most of the time i leave home 3 hours before scheduled flight, it can take 1 hour to get to the airport (depending on traffic, usually 20 minutes), and then all of the above. 3 hours can get me almost 200 miles away, and then I'm left with 150 miles of driving.

NorCal to SoCal using regional airports (avoid sfo lax etc) can be less than 2 hours door to door. Online check in + no checked bag means you can show up at small airports 30 minutes before takeoff. 50 minutes in the air, 10 minutes to deplane and leave the airport, and less than 15 minutes driving on either end and you have 2 hours door to door (and a lot more leg stretching than driving the 5).

plus adding in (I think) the magic number is 400 miles when flying becomes safer than driving.
