jetBlue of course
Of course I will fly jetBlue into OAK and LGB. What I will not do is fly into LAX because the traffic is horrible, regardless of how cheap the ticket is. If I wan't cheap tickets, I'd go to hotwire or something, but I don't look for cheap tickets, I look for the best value. As for SFO, I'll fly into SFO on American or America West but in the pass I did find cheaper tickets on American between SFO and JFK. Because all of my trip starts in the Bay Area or Sacramento, I also take into consideration of how much parking is, therefore, I am willing to pay the extra $50 or so on jetBlue and fly out of Oakland because thats about how much more i'll end up paying for parking at SFO.
