It is simple really...you could not take a 717 and fly it from ORD-SEA or from BDL-ORD-LAX without a number ot stops in between. Lets just say there is a 717-300 created, pushing 150' in length nose-to-tail. That would still be outclassed in capacity and range by a 738. AA was growing and needed growing plans.
As for YX in 717s...hope to see them flying over the eastside of MKE on approach very soon.
