The newest revision of our travel management system (booking, expense reports etc) allows for redress numbers to be stored in our travel profiles. Since the upgrade, if you book any air travel through the system (and you have to use the system to do so) it will demand your gender and date of birth which will be stored in your profile. This is odd since that info is coded into our master personnel/security files from which the system automagically plucks your legal name. Why it doesn't get DOB and gender, I don't know. If you also have a TSA redress number, you can include it to "help" you speed through check-in.
