You may be right about PSA getting the CRJ-700s. I saw an article where Andrea Ahles of the Fort Worth Star-Telegram said that Piedmont was going to get them, but that didn't make much sense to me, since Piedmont is all Dash 8 and hasn't announced a retirement schedule for them - other than one or two each of the past couple of years. PSA flies nothing but CRJs, so that sounds more plausible. In mid-2014, management said the CRJ-700 transfers would begin in mid-2015 and be complete by end of 2016 - but I don't know if they ever started.
