I saw from fftpilot that CHI is 80-90% 1 day trips. How long are these days? Think they'd be doable from MSP or at least to arrive back home at MSP after the days done? I know commuting's a pain, but I'm trying to figure out how to have a base preference. I'm hoping for ATL, DEN, or DFW since those have the most 2-, 3-, and 4- day trips.

If anyone has any advice, I'm all ears.
