One of the folks at Boing Boing got caught up in a TSA snag at LAX:

  I flew from JFK to LAX today, and something really weird happened when I arrived (at about 230PM local time).

I walked from the arrival gate towards baggage claim, and when I was
about halfway there, all of a sudden about a dozen or more TSA
personnel and private security staff appeared, shouting STOP WHERE YOU
ARE. FREEZE. DO NOT MOVE. Not just at me, but all of the travelers who
happened to be wandering through the hallway at that moment.

Some of the TSA guards then backed up against walls in the hallway, and
sort of barked at anyone who tried to move a few feet away from their
"spot," like towards chairs to sit down or whatever…

After 30 minutes, the TSA people said, okay, you may leave now. And
everyone unfroze, and went and got their bags. No explanation. I guess
I should have pressed for an explanation, or demanded to know why we
were being held without our consent and without a provided reason, but
I was really tired and just wanted to get the hell out of there and go
home. Perhaps I was wrong to have just walked away.

Add this kind of experience to extended delays, cancelled flights, seats that most 10 year olds can barely fit in and having to mull about with thousands of other travelers just as annoyed as you are and you can see why I don’t fly anymore unless I absolutely have to.
