The argument about DTW and MSP stagnation is moot as there really isn't an alternative right now. Skywest at DTW being the exception - for now.
MSP flying has shrunk from mainline through all the regionals. Fact of life.
Makes the argument of living in base vs. commuter less than clear cut. At least commuting gives you some flexibility in these situations.
...or people move to the base with movement. Like what happens at any other job...
