I am signed up for pre-check, and I never rent a car in LA, so I always cab to LAX. I have no status on WN and my current activity level on WN isn't enough to get it.
I live in the middle of San Francisco not particularly near a BART station and I hate hate hate flying out of OAK. I am lucky enough to be able to expense a car service to either SFO or OAK, but I try to keep in mind that the ride to OAK is about the same price as a one-way flight to LAX. Plus it takes much longer. I have switched from LAX-SFO to LAX-OAK when delayed but the ride back to the city is long enough that it's often the same total amount of time as just waiting out the delay.
