I hear ya brotha. As a fellow commuter, it really sucks when flights are downgraded from DC9s and A320s to CRJ200s, 900s, and E175s.

Don't know where the flight to SEA will originate from. If I have to guess, it would be from MSP or SLC or DAL outstations in the West. CRJ900s have the range to do it from DTW if they want to but that is not likely.
