I'm waiting for the Air Train to the BART station finally. Not sure if I'll make it to the Walk for Life at all. Other flights from southern California to San Francisco at around the same time seem to have been delayed about half an hour while ours was delayed about 1-1/2 hours or more. Not sure why. Our flight crew seemed to think it was system wide but flight status check online of other flights shows shorter delays for others. Since our flight had a lot of passengers with international connecting flights, I'm guessing there must have been foreign names on the passenger list that were checked out. But that's just a guess. So I'm on my way now to the city and will see what happens when I get there.
