Nice!

Any idea on the cost (CASM, 500-1000-1500nm trip costs, block hour costs, etc)?

If 50 seaters are so insanely uneconomical, I can't immagine 70 seaters or 90 seaters with 76 seats installed can be that much better.

In any case, 255 of the large ones is way over the top and that number needs to be radically slashed in C2012 or it gets sent back to the NC, even if they take their toys and go home, quit and have to start over.
