Regionals have received their largest aircraft. I think what most people don't understand is that there is NO 100 seat aircraft available except for the E190, and most airlines are not impressed with the product. Not to mention that most airlines, including DAL aren't interested in a 100 seat airplane. It's looking like 130 pax min is turning into the new norm.

It's unlikely that the airlines will attempt to fill the gap between 76-130 seat flying.
