Oh and then there's this:

Memorandum of Understanding
It is hereby understood and agreed, by and between Southwest Airlines Co. and Southwest Airlines Pilots’ Association, that upon ratification of the Parties’ new collective bargaining agreement, the Parties through their designated representatives will initiate a joint study of the feasibility of an alternative automated bidding system. Upon completion of their joint study, the designated representatives will make recommendations to their respective organizations.

Looks like PBS in disguise to me.
