The last time I flew through MEM was in November 2002 on the way home from depositions in New Orleans. My boarding pass for both MSY and MEM was labeled SSSS, so I had the "pleasure" of secondary screening when I departed MSY and also at the gate at MEM. I tried to explain to the gung-ho screeners that I was just changing planes and had been cleared in New Orleans, but that was before the concept of checkpoints and sterile areas occurred to the geniuses at TSA. Oh well, two more sets of hands going through my personal items, no big deal. Good luck to you this time at MEM.
