I specifically got GE so I could skip the immigration lines and use TSA pre-check. Unfortunately on my last two international trips I have been denied TSA pre-check in LAX since there is no indication on my boarding pass that I should get TSA pre-check. Evidently boarding passes printed outside the US don't show TSA precheck. Showing my GE ID made no difference. I have now been told twice by the TSA personnel in LAX that GE has no impact on TSA pre-check. It appears the only way I can take advantage of TSA precheck is to stop at an airline counter in LAX and get a new boarding pass printed.
Is this the same experience others have had?

thanks
