The rights referred to in the Constitution do not exist in transactions between businesses and individuals, except insofar as Congress has provided through regulation of interstate commerce (the Civil Rights Act of 1964, for example).
Hence, while you are riding in someone else's airplane, you cannot make a speech, carry a gun, quarter a soldier under your seat. You are not free from unreasonable searches or seizures, as long as they are not carried out by an agent of the government. You may not freely exercise your religion. You may not peaceably assemble in the aisles or toilets. And so on.
Interesting point and I will cogitate on it.
Thanks!
Wrong, -- and this judge explains why:
In Plona v. United Parcel Service, 2007, -- U.S. District Judge Ann Aldrich found that "allowing an employer to terminate an employee for exercising a clearly established constitutional right jeopardizes that right, even if no state action is involved."
