I've noticed that whenever I board with my eboarding pass that when the gate attendant scans my ticket, a red popup appears on her screen. They usually have to key something in and then rescan my ticket.

I just so happened to look at the screen this week and i noticed it said "TSA*** " along with some text in that red box.

Anyone know what that is? or encountered it before?

I do plan on asking next time it happens, but curiosity is getting the better of me!
