Going, but not gone. I'm not defending CVG's future, but let's dispel the myth that it's already de-hubbed. It's a heck of a lot smaller than it once was, but DL still has a hub operation there... however numbered its days may be.

MSP is actually more affected by snow than DTW.

Except for Asia, which is where the major growth and profits are right now. Aside from the recent plan to add-back a few weekly ATL-PVG flights, the road to Asia on Delta still runs through DTW, NRT, or to a lesser degree, SEA.
