By that logic, you could say that a road is public property and that by driving on the road, you automatically consent to a search.

This isn't the way it works. The Fourth Amendment protects people, not places.

Wrong, the airport is a restricted area.The article says the searches are being done upon entry, a prerequisite. When you enter a government building you go through the metal detector, that is a form of search, same as when you board the plane.

so then all luggage searches at airport check-in violate the 4th amendment too?
