Before our last flight noticed the Trusted Traveler number missing from my wife's ticket confirmation so I called and they told me it was a computer glitch and they would add it in.

It was not a random denial with GE but might have been blamed on that had it not been caught prior to printing the boarding pass.. We have had GE for just under 5 years and have ALWAYS had precheck where available.

I would blame booking issues first before declaring it a GE issue.
