I'm telling you that your rights are not, and cannot be, absolute. You do not have the right to fly on a plane that does not belong to you, free from any scrutiny whatsoever, because your general right to travel does not guarantee you a particular method by which you can travel.
Asserting rights beyond what is enumerated in the Constitution is an exercise in wishful thinking. Both the contractual obligations of your ticket and the Commerce Clause of the Constitution provide ample justification for consensual searches of passengers - the Fourth Amendment is simply irrelevant, since the search is entirely consensual. If you don't like it, you are free to refuse to be searched, and then travel by some other means. You can always take a bus. Or buy your own plane. But the Commerce Clause clearly and explicitly gives Congress the right to regulate interstate commerce, which obviously includes a flight from Portland to Las Vegas.

Once again, you tell me that I only have the rights my government listed in the Constitution.
Rights do not come from government, general_re.

"Regulation" does not include government agents searching people without warrants.
A search is not "consensual" if it is forced upon you.

We are "free" to refuse to do our job, if the job requires that we be four States away tomorrow morning?
We're "free" to give up a three day vacation in Hawii?
Air travel is a requirement of a major segment of our society, and a welcome luxury for all the rest of us.
Travel is a right. The fact that our government is infringing on that right does not negate it.

True, a commercial flight from Portland to Las Vegas would qualify as interstate commerce.
A commercial flight from Houston, Texas to Austin, Texas does not qualify. Even so, the same regulations are used, whether between States or within States.
The federal government does not have the authority to "regulate" commerce inside the individual States. The fact is that the Federal government actually does regulate commerce within individual States.
Our national government has usurped powers not granted to it.
