The promise of large RJ flying was a stop gap measure to get people to stay as was the supposed Flow Through provision.
Nothing prevents AAG from promising and taking a few large RJ's to accomplish the short term goal of transitioning from the 140/145 fleet when a critical mass is reached. That is all they care about not some loyalty reward program for pilots who gutted it out and made it work. This kind of thinking will get you a door slam to the derriere in the "end."
