Doesn that article reference "Delta's fleet optimization plan"? I thought that the addition of the 737-900ER was to begin in 2013 also.. Those aircraft are "cash accretive" from the first day according to previous company memo. Also therre are 30 more "fuel efficient" MD-90's that will cut costs too that will occur in 2013.

The "plan" has lots of moving parts... Just because this article doesnt mention other aspects of the fleet optimization plan doesn't mean that those pieces cease to exist.
