Red herring.......that'll be the new phrase here after the posts on the other thread.

"do you really feel that if an airport crazy knew your last name you are more likely to be physically assaulted?"

Not in the airport but this person could find info on an employee they had a disagreement with and cause harm to them, not just physically. If I want to give out my full name to someone, I will. I shouldn't have to worry if a customer gets my last name if I'll be defamed online without knowing about it or have it used to harm my financial records or to be located in my home. That is a choice I want to make and I choose not to give it out.
I said it before and I'll say it again, first names, employee numbers along with dates, times and cities are more than enough to identify an employee. Having the last name is of no more help and is un-needed.

Edit.....I agree with you that Dana didn't want her first or last name taken and that is wrong. She is hiding something but could have been easily be identified with date, time of flight, city and gate number. Not that hard.
