The likely outcome of your choice is highly tied to what Delta does. If Delta furloughs 400 pilots they will have the ability to completely flush the Compass list and fly those E-175's. Your furloughed now, so really there isn't much to lose other than possibly giving up recall to RAH then getting furloughed again from Compass if Delta furloughs. If Delta doesn't furlough, then you'll probably be OK and have the ability to flow up to Delta without interviewing which for a SLC guy could be a good thing. If you don't have anything else going, I'd go for it if you can live with a commute to DTW.
