My personal data on this front is 20 years old, so please keep that in mind.
I want to college in Shallow Alto, and worked for the following 2 years in Mountain View.
I had to go to Los Angeles 1x per month.
I used AA to fly SJC-LAX because our LA office was really close to LAX.
But, if Burbank was more convenient, I would have flown WN in a heartbeat.
