Flew LAS - ATL / ATL - LAS starting on the 10th of this month and arrived home today. Went to the TSA Pre line and was rejected both times. Have a NEXUS card and Delta was given the redress number at the time of booking.

Needless to say that in the future I won't bother with Pre as they seem not to accept trusted travelers.

To update: In the original post, I wrote that my Nexus number was in the redress space, checking back at my Delta Airlines profile, my Nexus card number was in fact in the trusted traveler space. So, still getting shafted by the TSA.
