Ok, so I was looking on-line for June 10 SFO-LAX flights, there is one at 6:18pm and then the next one not until 9:30pm on United.com. However on United Timetable it lists one at 7:22pm and 8:13pm as well.

I was originally on the 7:22, but rebooked onto the 6:18, since I wanted a buffer. We are connecting to the TG flight. If the other two are really not available, then I'm wondering if I should go with the 5ish flight as to make sure there is still one buffer one.

ANA shows the 7:22 and 8:13 as well.
