I fly about 6 times a year, and I have had only one problem with TSA. I follow the rules for liquids and pocket knives; I travel lightly on the plane to avoid awkward situations, and I wear slip on shoes to simplify removing and putting them back on.
However, I sent in an email complaint over a year ago when I had the one bad experience. I received the standard email acknowledgment of how important my comment was. However, I have never heard another word.
Basically, I flew Colorado Springs to Houston, changed planes (not airlines) and flew to St. Louis. I had the nice little note about the TSA search. However, this search was conducted outside in the rain in Houston! The papers I had in my luggage were ruined by water and my clothes were soaked. Fortunately, I was home, but what if I had been on the way to a meeting and my materials were damaged? How easy is it to dry your clothes in a hotel - I don't travel first class.
Most of all, why didn't the TSA have the courtesy to respond to my comments. Are you really 14 months behind in handling complaints?
