I'm quite an accomplished researcher, thank you very much. The fact that Alaska Airlines writes those regulations into its contract of carriage demonstrates that they are indeed a common carrier. The rules under "refusal to transport" must apply equally to all paying passengers, and no passenger may be refused transportation except under the specific conditions Alaska Airlines set forth there. A common carrier does not have the right to refuse to transport passengers, except according to objective and non-discriminatory standards like those Alaska has written out.

But now we're getting into minutiae.

Back to the point of the thread, if government officials can not keep their hands off our private parts, we should: (a) avoid flying at all costs, because that spares us personally of the pain of physical abuse, and (b) fight like hell until Congress / the courts dictates that fondling the bodies of non-suspects in an airport is illegal / unConstitutional.
