Okay lets break this down further. There will be no mergers between Comair, Compass and Mesaba.

seamless integration (Keyword) after the merger closes across all of the following areas: fleet, ground/ACS stations(Compass and Mesaba fleet and stations to DCI), IT, supply chain, facilityand maintenance operations, HR, and others.( All these functions will be performed by the holding company)

Each airlines will have their own maintenance dept, but the managerial aspect will be controlled and centralized at the holding company. The main HR, IT, and so on will be at the holding company. So all three w/o regionals will operates on the same syatems and programs like I've been telling you guys. The only way it affects the other DCI carriers is to streamline the DCI product
