They are down to 57.4% of system departures in March, 2012. If you look at system ASM's (again from OAG) they were at 14.5% of system ASM's in January 2010, and will be at 13.8% of ASM's in March 2012. Your assertion that they are replacing mainline flying doesn't match with the math. DCI as a percentage of Delta flying got smaller.
