Yeah they changed that pretty quick. It hasn't been like that for years now.
I don't fly often, but I did a few months ago, and every airport didn't have a single scanner machine running, it was all metal detectors. I don't know if the machines broke and the money to keep them running dried up, or they just stopped caring, or what.
Every time I’ve flown in the past few years they’re still using the scanning machines. I have PreCheck so I get to skip them and go through the metal detector, but the machines were still there scanning away.
I’m well aware. Read what the person I replied to wrote, about how they don’t even use these scanners and use metal detectors instead. That is not my experience.
