I applied/filled out info on TSA web site to be quailifieed for TSA Pre Check. Question is:::How or when will I know if I have been selected for Pre Check on a flight? Rules state that the bar code is coded to show your status for Pre Check but not readible with the naked eye. Rules also state that one is should not expect to be selected for every flight, how will I know/find o ut that I do or do not quailify for a flight. I fly thru Atlanta to Vegas and both airports use the TSA Pre Check. Any info appreciated.
