Insanely long lines for both Clear and PreCheck this morning at Terminal 3 in SFO. Of course, every Clear passenger is being asked to complete the whole Next Gen upgrade thing, which involves new face scans and ID scans and phone number verification code things, which just slows the whole process down. Plenty of passengers near me declined. I was lucky enough to find a short Clear line closer to the the International Terminal without PreCheck. I'll take my shoes off if I don't miss my flight!
