Detroit is such an under utilized airport and would be able to handle a lot of expansion from Delta. One thing I have heard is through the jv with aero Mexico is that delta will potentially serve Guadalajara and Leon from dtw soon with increased service to Monterrey using delta planes and not aeromexico. I don't wish anything bad on msp and I'm not sure i believe this but each year that goes on there are more and more people that live in metro Detroit that work for delta and this would be great news if there was expansion, especially if it doesn't involve taking anything from msp
