Eaglefly, what do routes have to do with it. Regionals don't set the routes they're going to fly. Regional management doesn't tell mainline these are our routes and those are yours. No regional owns the flying it does. If mainline management decided to bring all of the flying back in, there is nothing the regionals could do. It's not going to happen but there isn't anything they could do about it.
As for profitability, I would say that most managements don't know how to make a profit.
