Well, we are flying Delta out of SFO, with a short layover in Atlanta. SWA does get you to Orlando, but I have found that their times are bad. United has a nonstop, but it's usually expensive. Delta has a non stop, but it's overnight. US Airways also has a non stop.
Go to Orbitz.com to get an idea of flight schedules.
have you considered flying out of Oaland or San Jose?
