From what I was told, PDT tried to get some planes based at PHX and Messa through a fit about it. So I believe that they are holding off on new classes until Jan. b/c they are trying to get things fixed in PHX (which is just speculation) and/or since the holiday's are coming up they don't want to run any new classes. I don't think that PDT is the only regional out there that is holding off on new classes b/c of the holiday's so that might be more of the reason than their deal in PHX.
That sounds about right. SF says attrition is down 10% from last year (according to the ATW artice from the employee site.) Everyone I know around the burry is planning on 'riding out the merger' here.
