Being that there isn’t a realistic replacement aircraft for the 50 seat niche, the niche will eventually adapt or go away. Some markets may not be served. People in CLL can drive to IAH. Other markets could see fewer flights on larger aircraft. The regionals can fly the 70/76 seat jets allowed by scope to the smaller markets and mainline covers the rest using what ever the company decides that we fly. It took us years to get here, and changing won’t happen overnight. It will be interesting to watch it unfold though. The current 50 seat jets will eventually have to be replaced. The question is with what?
