They only have the power to regulate commerce among the states, with Indian tribes, and with foreign nations. How does air travel apply?
Even if you're going to use the wildly distorted "interstate commerce" view, there's still that nasty 4th Amendment there.
Also, if the government isn't personally searching you, (but instead telling someone else to search you) they can probably get around the fourth amendment,
No, they can't. There's nothing in the 4th Amendment allowing them to do it. Besides, they are doing it, directly. These are TSA employees.
