So, with this rumor about the -200s moving up to DTW in the fall, there might be something to it. Looking at the schedule in October, there are a quite a few cities (CVG, MKE, PIT, MSN) that are getting several XJT flights from DTW on the -200s, more than usual compared to right now. Not sure if it will justify a 200 base, but it appears to be an increase.
