50 seaters can still make money, they just have to be full or almost full on most routes. There will probably always be a niche, but odds are that smaller RJ's move away from mainline routes and go back to doing what they were designed to do in the first place...right sized service to Podunk Falls, at a premium price.
50-seaters will make more than a 70-seater and 90-seater anytime there is less than 55 seats sold.
You forget that 15 seats sold on the 70-seater is the same as the 50-seater (minus first class of-course). The 70-seater costs more per hour, gas and cost of the plane (its newer and bigger)
