Looks like some front/back office as well as some operation stuff for all three w/o regionals will be conducted at the controlling entity for all three carriers. I'm guessing MC Holdings will morph into this entity post merger.
Companies Plan Future Regional Carrier Strategy
The Regional Carrier Strategy Integration team, led by Don Bornhorst, SVP-Delta Connection, and Bryan Ebensteiner, Northwest VP-Finance & Business Development, continues work on a number of merger-related initiatives. The team is responsible for crafting all aspects of the future company’s regional strategy - from how to standardize experiences and products across its eight regional carriers to how to streamline supply chain and purchasing spend.
Composed of more than 20 functional experts, the Regionals team includes members from Delta Connection, Comair, Mesaba, and Compass. The team is working to ensure a seamless integration after the merger closes across all of the following areas: fleet, ground/ACS stations, IT, supply chain, facility and maintenance operations, HR, and others
