Some freight stuff flies out of there, Falcon 20s or DC-9-15s, as it's close to final assembly plants. There's a flight school I think, and probably a little corporate. Never a busy place when I was on a trip going through there.

About 15 years ago, an airline called ProAir tried to make a run at it there. DET-EWR, DET-LGA, DET-MCO that kind of thing. It was supported by GM I think, as they were trying to get lower fares out of DTW and the airlines there weren't playing ball. The only problem was, from what I hear, that if the weather was crappy the 737s they flew couldn't land, as the runway was too short (5,090 ft). Airline lasted a few years if I remember.
