You know u guys are pushing it with the Boeings and Airbuses with high cycles.
There is a reason why the DC-9 and DC-8s r still flying today, and u don't see too many 707s or 727s. The hulls on DC airplanes are thicker and can handle more cycles than Boeing. Now i don't know about the 717, but I bet it can handle more cycles and would be a good replacement for 737-300 short leg trips. The Boeing and Airbus planes are only designed for about 25-30 years of average life. I say average for average cycles on the airframe. It is also the reason why Mcdonald Douglas is no longer with us. They made the planes too thick in the hulls. They last too long. Less repeat customers maybe.
