Sorry, I don't have current info on the afternoon security line lengths for gates 1 to 17, since CO dropped SFO-HNL service around 2000.

Before the 22 June 03 BART opening, I used to cut through the International terminal on foot.

Now it is so much simpler to take the AirTrain, which loops around SFO airport. It is one level up from the departure area.

Continental's Presidents Club is outside security, so the length of the line is important for any frequent flyer departing on CO who wants to use the lounge.
