I dont have a good answer on why someone would want to do it either, but they are. I received a PM from someone today who had information about me, my travel and my Delta flights that there was no other way they could have gotten other than they were a Delta employee who had accessed my record there. And was later able to verify that yes the person was signed in via a Delta line. In my case I believe they were able to figure out who I was using the routing I had posted when I asked for seating information. But it got me thinking about how flight connect could be used the same way by them tying together your same segments and your flight numbers (something I hadnt considered before when listing my flights on there).

I am not at all suggesting people dont use the function, because I think it is a great program with an admirable goal, I just wanted to warn people so they dont get the same surprise I did today.
