I'm not sold on the 717 option. It brings with it most of the cost issues of the 318, without any of the benefits.

And what of the 767's? I am guessing that Phase II will see all the CP birds on a one-way trip to NM. (To resolve those conflicting power plant issues). But the older -200's are getting on in years. In theory the 321's could pick up the domestic slack, and the 330's the international, but these aircraft actually bracket the 767, rather than replace it. (Hmm...)
