Cant speak for DTW. But even when I was a super jr lineholder in ORD, I was getting commutable lines both ends. But I bid for that above all other preferences usually. Something like 9:45am and later starts, release by 5 or 6 pm. So I guess it depends on where you are flying from. ORD seems to have alot of commuters from all over just from what Iv observed, and most the “local” guys that drive to work that I meet either drive from WI, IN, or even western MI.
