Might want to do a little research here. Here's a link to the 24 cities Delta reduced or cut service to:

Delta Air Lines Newsroom - Press Kit

Of these 24, 17 are EAS subsidized and 7 are not. I think it's safe to say MOST are EAS subsidized.

Of these 17, 4 were awarded to Delta to be contracted out by them to one of their code share partners (Hibbing and Escabana to SkyWest, and pelliston and Sault Ste Marie to Pinnacle). 3 were awarded to SkyWest (Alpena, Iron Mountain, and international falls). 6 were awarded to Great Lakes (Thief River Falls, Devils Lake, Watertown, Ft Dodge, Jamestown, and Mason City). And 4 were Awarded to Silver, but these 4 were always flown to either Memphis or Atlanta, so they are irrelevant (Greenville, Muscle Shoals, Tupelo, and Hattiesburg).

So, that's 17 EAS contracts, 11 to SkyWest and Great Lakes, 2 to Pinnacle, and 4 to Silver. So once again, I think it's safe to say MOST were awarded to Skywest and Great Lakes.

As for the other 7 unsubsidized out of the 24 cities, 3 are serviced by SkyWest (Butte, Aberdeen, and Bemidji), 2 by Great Lakes (Pierre and Brainard), and the other two were always serviced by Eagle (Waterloo and Sioux City).

This brings the total distribution of the 24 cities to 8 for Great Lakes, 8 for Skywest, 4 Silver, 2 Pinnacle, and 2 Eagle (Again, safely saying most went to Skywest and Great Lakes).

So where exactly is this opportunity for Silver to pick up flying for Delta out of MSP?
