No, just Southwest. At the time they'd run a flight every hour between SJC -> BUR and after a while it became really easy to gauge exactly when I could show up and hop onto the next flight out. Cut it too close and miss a flight? They'll just put me on the next one. No big deal. The smaller airports help enormously in getting in and out fast -- I could walk into SJC and be on a flight in a matter of minutes. SFO and LAX are gigantic time sinks.

Though in Musk's case I imagine he can do the private jet thing and have the plane wait for him.
