Beware the operational sub! Was bored on a conference call and browsed a few hundred pictures on a.net. Looks like Skywest has somewhere around 15 CRJ-200's flying around sporting Skywest livery, and one CRJ-900 and no 700's.
Good news, Skywest has the fleet to bring in another plane during maintenance, irrops, etc. Bad news, it will probably be a 200!
