Just arrived at the AC here in SFO after CLEAR insist that I use security at T1 since there was a huge back up with CLEAR as well as PreCheck (I have both). Was told that since I'm departing from Gate 45, I shuld use that security checkpoint. So, I made the walk over there, 2-4 min walk, and I was the next one to walk in to CLEAR and then PreCheck. Amazing difference! Then I made the walk back to to T2 for AC as I'm about 1.5 hrs early for my flight. Oh well!!
