A few questions:

The slides (Thanks acl!) show retiring of "120 of our least efficient aircraft over the next 18 months including DC-9-50, Saab turbo prop fleets, and 60 50-seat regional jets".

Weren't these cuts previously announced, and there's basically no additional announced fleet reduction?

With our DCI agreements, how does Delta go about saying to one of them that we want to eliminate say 25% of their fee for departure 50 seat RJ feed within six months?

I would think with fuel prices where they are, and knowing that the 50 seat RJ loses money, DAL would want to whack that fleet segment pretty hard.
