The MD is at like 92% reliability. Mitch wanted a higher number like 96%. Mitch is the new boss over R. Barr. Mitch decided to move the MD over time to domestic as the 400 comes along. MD will be about half Intl. half domestic within two years according to some in the know.
Also looking at the 777 at these high fuel prices. This is maybe why they stopped the MD at 38 frames.
