How is that a solution? If you're about to take a flight, you already spent a bunch of money, which usually means you really want or need to get to your destination.

Leaving doesn't solve anything. You think TSA gives a crap? No, they get paid either way. You think airlines give a crap? No, they already got your money, and now they have an empty seat that they can resell (via the overbooking process).

The real solution is to sue.
