Interesting analysis. Having flown several times through CVG that if it becomes a hub I will change airlines

MEM is toast.

If it comes down to MSP or DTW I'd gamble that only one becomes a hub. Maybe one as a domestic hub and the other as an international hub?

Weatherwise, I am much happier to be based at MSP rather than any of the others, summer or winter.

Cheers!
