For those of you who went through the security at SFO, is there a Global entry(Nexus) only line? I am thinking to maybe step out for a quick smoke... while waiting for my next flight. My first leg is YEG-SFO arriving local time at 9:50am, and next flight departs at 1:10pm; SFO-ICN. So I have about 2.5 hour window. If there is separate Nexus lane which I can take, then risk of missing or even running to catch my flight will decrease. If there isn't one, I guess it is time for me to quit...
