If you join GE you can add your Trusted Traveler Number to your airline reservations. Reports on FlyerTalk are that most get PreCheck 99% of the time after that. The other way of joining Pre was to hold elite status on a participating airline and opt-in. This yielded far less success, anywhere from 0-90%. As a United platinum member I was getting Pre about half the time, traveling weekly. I got GE over the summer and have gotten Pre 100% since then. Even if you're eligible for Pre, the TSA doesn't always grant Pre as a "security measure."
