I also really enjoy SC. I especially like their feature where for $75 you can upgrade nearly ANY FLIGHT (based on availability at checkin) at the airport.

I also find their staff much freidlier than NW. And, HHH from Minneapolis is WAY better than MSP. Much better airport. Avoid taking the lightrail to HHH, though, because the walk is rediculous from the dropoff to ticketing.

As a 3 year Platinum, I am considering switching as much business as possible to SunCountry. Their value consistently exceeds NW.

Off to check out the VIP program.
