This isn't requal or differences training. You will be qualifying under a new training program for a different airline that is overseen by a different FSDO. This is no different that you quitting Mesaba and going to work for another airline. Coincidentally, that's what you'll be doing. Welcome to Pinnacle!
Yes, and they have had four months to figure out how to do that. The answer to the thread's question is that the vacancies should be open right now. We don't know if the company is ready or not, but they should be ready because they are open. If they don't honor that, then there will probably be bypasses, people sitting on their ass while they figure it out, or somenoe getting 200 captain pay while they are an FO. It's not our problem the company can't honor our contract, but damn straight they are going to compensate someone when they don't follow it.
