Getting a -900 program up when you already have a CRJ program isn't that difficult. I know Air Wisconsin already has part of the plan in place. Sim is just -200, but training dept has a -700/-900 syllabus and sections of the FOM blocked off for -700/-900.
Gojet.... Who knows?? They can barely staff what they have. So I can't see them getting another 30-40 planes and being able to have any sort of completion factor.
SKYW..... Respectable company, and already in bed with Delta. If Skywest Inc has the cash and the staffing to get it done, and delta wants to make them their mega regional (something they vowed not to do post-Comair strike), then I could see SKYW getting it.
Realistically PNCL will probably vote their TA in, get the airplanes, and get the options. Mid-Jan we will all know either way.
