For me, on TCONs, don't really have much of a choice. SJC is too far, and no way I'm sitting on WN on anything longer than 90 min. So, it's SFO or bust on TCONs. Now, on shorter flights to LAX/LAS, definitely prefer WN out of OAK, especially now that the BART connection is finished sparing us from that Bus ride from the station.
