Several hundred $$$ for me. Most of one day at DCA, then another at the Balt FSDO. Not counting mileage, just leave. . .I can't remember what the fee was. TSA was collecting PII on a pirate form then, and then left 'em lying on the counter for casual reading. The paper-shover had to step away for an hour or so. . .dropped the dime to OMB.
I believe the local FRZ airports are keeping hard copies of the forms, with SSN, name, address, birth date, etc. in their highly secure file cabinets, with acess limited to only those who can pull the drawer out. College Park actually locks the cabinent. Pretty sure that's not the case universally.
Threw in the towel after OPM & BC/BS passed my PII to China, and my mortgage company the VA left my data on the front steps, too. Just fraud alerted all three credit agencies and moved on.
Almost supernatural incompetence by OPM and the VA. But then, that's always been the case with both of them. It's just that now they have have much riskier toys to play with. . .
