Maybe all the Code F stands were occupied for some reason, but the AF made it in OK. I think the EK went straight in to OAK, then was sitting in a holding area by the threshold of 30, last I looked.
NKB, take a look at a map of the Bay area and see where SFO and OAK are compared to the city. I've hopped between the two in a taxi and it's a fair drive in early evening traffic.
