You are a PR and havent gotten TSA-Pre even with GE and FF status - read on
I am an LPR, I don't travel a ton - I am just a UA Gold.
I got the Global Entry late 2012 and have had my KTN in my Mileage Plus Profile since - I have never gotten TSA-Pre.
So I spent the $85 got the TSAPre Enrollment this Jan - they gave me a new KTN which was alphanumeric ( my GE KTN was all numeric). I updated my Mileage Plus Profile with the new KTN and since Jan I have made 4 domestic RTs and gotten TSA-Pre everytime!
