Lists
I'm on the list (I think)
ESTA's were fine.
Was trying to check-in online and I got flagged. The rest of the family didn't. I asked and was told I was on "a list" and had to go through an extra hour of security checks...
Then, at the airport (both sides) - I get the extra checks (ballistics, everything).
Sadly - I've normalised it so turn up earlier to expect it now.
