And before anyone gets bent, case law supports the concept that a traveler in some situations has voluntarily relinquished certain rights.
4th amendment rights - voluntarily waived the instant you set foot on airport property.
5th amendment right to liberty (meaning in this case the right to travel freely) - voluntarily waived as well.
Lots of interpretations, here is a good one outlining where the basic rights go when you enter into a contract that waives them.

One applicable section (regarding highway travel but relevant to air travel as well):
Here is what the courts have said about this:
"...For while a citizen has the right to travel upon the public highways and to transport his property thereon, that right does not extend to the use of the highways...as a place for private gain. For the latter purpose, no person has a vested right to use the highways of this state, but it is a privilege...which the (state) may grant or withhold at its discretion..."
[State v. Johnson, 75 Mont. 240, 243 P. 1073 (1926)]
There are many court cases that confirm and point out the difference between the right of the citizen to travel and a government privilege and there are numerous other court decisions that spell out the jurisdiction issue in these two distinctly different activities. However, because of space restrictions, we will leave it to officers to research it further for themselves.
(2) The second group of citizens that is legally under the jurisdiction of the state are those citizens who have voluntarily and knowingly waived their right to travel unregulated and unrestricted by requesting placement under such jurisdiction through the acquisition of a state driver's license, vehicle registration, mandatory insurance, etc. (In other words, by contract.)
We should remember what makes this legal and not a violation of the common law right to travel is that they knowingly volunteer by contract to waive their rights. If they were forced, coerced or unknowingly placed under the state's powers, the courts have said it is a clear violation of their rights.
It means that the govt can come up with a requirement for travel (issuance of real ID, pilots license, etc) and by accepting the terms of such license you waive certain rights.
