Commuting sucks, but it isn't the worst thing ever. Most of the time things work out just fine in my experience. If you are willing to accept that every so often you may have to commute in the day before or commute home the day after your duty period, then you'll be okay. It does wear on you though. For instance, I have to wake up at 4:45AM tomorrow to make it into base for my 1100 short call duty period. That sucks. If I lived in base, I would just roll over when the alarm clock says 1100, hit snooze and call scheduling to report in. But that just isn't the case for me. That being said... if it were me personally, I would see how many daily flights there are between DTW or wherever you commute from and where you would be based. If there are several daily flights with early and late schedules, I might consider Piedmont. If not, go with Endeavor. I honestly think no matter where you go there will be movement and upgrades over the next 5 years as the hiring at the legacies and majors picks up.
