I am on the SSSS list too.
I’m sure FreePers are at the top of the list.
Years ago I had to go on last minute travel.
My ticket was one-way there, and one-way back.
No carry on luggage, last minute, traveling alone.
My boarding passes had SSSS stamped on them at each stop along that trip.
And they waited until the last passenger to call me, and put me through the ‘turn around, belt off, we are going through your bag, etcc. while the plane load waited.
And I knew it was coming, I figured out the SSSS real fast.
