I've never seen anything close to an hour at PDX for PreCheck and honestly this is really hard to believe. I've gone through PDX PreCheck +/- 10X over the last six months around 6/7AM and have never waited more than 10 minutes. An hour on a Sunday morning and worse a week earlier? Hmmm.
One thing notable when I went through this morning is that the PreCheck line is now to the left of the general boarding line. The new side has you put everything in bins where the old setup was just throw bags directly on the belt. When I first read the post I was thinking maybe there was some changeover/confusion/problem on Sunday AM with the move and new equipment but that doesn't explain the "even worse" a week earlier.
Out of curiosity, how far back was an hour (or worse) wait? Did the line snake back out in front of the ticket counter? During times of chaos I've seen the general boarding line back to where it gets mixed in with people in the AS ticket counter line. I can't even imagine how far back an hour wait for PreCheck would be.
