MSP is where I grew up and I do think it's a great airport. I really love all of the food options, and they have done a good job of remodeling and redecorating over the years. However, as a DL pax, I think the Sky Clubs are seriously lacking, even with the minor renovations that they did. They have not made any major investment in the clubs since the merger (same is true of DTW). Fro example, the restrooms, especially in the F club, are totally gross, and the club is very often overcrowded too. While the Twin Cities takes pride in their airport, DL seems to just see it as a fortress hub cash cow that is not worthy of investment.
