Airlines, Crisis Communications 101, and Prohibited Speech

"The Friendly Skies" unfriendly expulsion of a paying customer from one of its planes April 9 (fortunately a plane still on the ground) has produced a plethora of complaints, comments, and constructive suggestions. 

What seemed to me one of the more creative suggestions starts by accepting that the airlines are going to continue the business model of contracting with customers to perform something (air transportation between two designated airports at specified prices, times and dates) that the airline can unilaterally refuse to perform at any time -- up to and including immediately prior to a paying customer's boarding.
