If DAL goes through its plan to park most of the 50 seat RJs, most of the DCIs whether WO or not will continue to shrink. XJ only has 17 CRJ200s so even if they are all parked in the near future that is nowhere near as catastrophic as it would be for Comair, SkyWest, or Pinnacle which has in excess of hundreds of CRJ200s.
DAL will probably park all Saabs by the end of 2011 but after this year's cut, XJ is only left with 28 Saabs, and it looks like CRJ200s from all DCIs will not be safe from the chopping block. I think current DAL CEO is in a bit of a quandry due to errors made by previous CEO. Because 10 plus DCI contracts were signed away by previous management, DAL risk expensive legal battles if it tries to cancel DCI contracts with SkyWest/ASA, Pinnacle or CHQ. But his beancounters and legal advisors may give him the green signal to cancel them one at a time if the cost of getting sued is actually cheaper than going through with the continuing DCI agreements.
Current DAL CEO has said many times he wants to keep most of the DCI flying inhouse in the future. Whether he will be able to do so is a big question mark.
