I need some help. I am a Platinum member, and was approved for Global Entry (GE) in Nov 2011. For the next two months I successfully went thru PreCheck (PC) at DCA, LAS, and Orlando among others. About 4 months ago I stopped being approved for PC while going through TSA, and so far my last 14 flights I have been unsuccessful. Delta says its a TSA issue, and the TSA supervisors I have spoken to all agree that while the system is "random" and I will not get selected for the precheck line 100% of the time, that zero for 14 is indicative of a problem and that the problem resides with Delta (since they issue the boarding credentials). I flew on United this past weekend just to check, and didn't make it through there either. I have seen some blogs online that said a couple of months ago the PreCheck and GE name matching methods changed, and that could be the issue. No one seems to be able to offer a solution. Help.
