"Therefore, if some TSA lackie decides to harass me when I fly, I'll ask for the supervisor, and then dial the FAA..."

I don't quite get the point here. The FAA person can do nothing if your complaint is dealing with the TSA. The TSA Security Director, and airport security in itself has nothing to do with the FAA anymore. The fact that they transferred FARS 107, 108, 109 to 49 CFR (part 1500) puts this totally out of FAA jurisdiction.

So, why "dial the FAA"? You might want to add a TSA number instead.
