Everything I’ve heard indicates that NOBODY has been denied flying because of this. You will just be subjected to additional security screening. If you happen to be in a trusted traveler program, like TSA Precheck, then that ID card is as good as a Real ID. Military ID also. If you’d like to be certain before you pack, why not go out to your local airport and talk to TSA personally. Get the name of the person you talk to. Hope to see you at the convention.
