My whole point was about business flight. Sure for leisure I’ll take a train. But if I’m flying for work I’d rather deal with a consistent (mostly, compared to any rail I’ve taken) experience.
I've heard that the flight delays cascade throughout the day. So if the first flight is 10 minutes delayed, all SF-LA flights are delayed for the rest of the day. Since SFO has a lot of fog, my understanding is that it's often delayed.
Maybe it's okay coming from Burbank, but I live on the Westside so I have to take LAX.
I would love to have another option. Ideally, a train would decrease the load on the airlines so that they could handle delays better.
To answer your question directly, no I don't have to do work trips every couple of days, but I do have work trips from LA to SF every couple of months.
