This is what i dont understand though, if a privately owned airline decided they didnt want their customers to be searched, would they be exempt? Say if united decided they dont want TSA screening passengers, could they just walk straight onto the plane?
I had a good chat about this with a frontier pilot, and he said he does not know of any law or regulation that requires you to go through security to fly on a privately owned plane, the airline can refuse you service, but technically if you flew on an airline that didnt require a security screening, you would be able to refuse to be screened and pass on through.
Id like to see what law says you have to be screened by tsa to fly on a privately owned airline. Im more curious than anything, because as far as i know, you are not required by LAW.
