When we got our GE, Prececk wasn't a separate service you could purchase, as it is now. Still, we were told that, as GE fliers, we were eligible for Precheck. BUT that it was RANDOM. There have been two occasions in the past five years or so where one or the other of us has not gotten Precheck. And yes, our numbers are in our airline profiles, and are in our records of every single airline ticket we purchase. It's random, people! And if you think about it, that makes perfect sense from a security point of view!
