DL wasn't giving anything yesterday. Kinda nervewracking when WIGolfer was flying from ATW-DTW-MSP-GEG and it was touch and go DTW-MSP due to WX and MX issues. DL refused to reroute ATW-DTW then onward to SLC or ATL to avoid MSP.
ATW, GRB, MSN, and CWA are definately in much worse shape.
MKE hasn't got nearly as much snow as the upper valley. We've got a foot of snow right now 3-5 inches more expected today and winds are holding steady around 20 mph. Its gonna be a rough day.

Frontier, being based in DEN, is likely used to massive amounts of snow. The 6 to 10 inches that MKE is getting is likely nothing much for them considering what DIA has had already this year.
