The constitution no longer applies in the airport, according to the TSA, and also apparently according to the courts, so if you just plan to buy a ticket to fly like John "if you touch my junk" Tyner, that simple commercial transaction now means you are relinquishing your rights under the constitution:
Tyner was told by a TSA supervisor on tape, “By buying your ticket you gave up a lot of rights.” ...
According to [Michael J.] Aguilar, [TSA Chief, San Diego], Tyner is under investigation for leaving the security area without permission. That’s prohibited, among other reasons, to prevent potential terrorists from entering security, gaining information, and leaving. ...
Aguilar said that once a passenger enters the security area, there is a legal obligation to follow through with the process.
So by buying a plane ticket and entering the airport, you become the TSA's slave, in their view.
