I've had to take a few domestic red eyes from sfo and have noticed that between 7ish to 9ish there is little traffic but clear is open (although unnecessary), so when I got there at 10 a few nights ago and the lines were horrendous I was looking forward to using clear. Guess what - it was CLOSED. I got there about 2 minutes past and the TSA said they closed at 10 (but given the barrier up and no one in sight it must have been earlier) So..... I get to go through the "1st class/priority" line (which isn't priority since everyone with a cc gets to go there) and it takes 30 minutes! Open when it's not needed, closed when it's desperately needed Don't think they have convinced me to pay for their services when renewal comes around!
