As of the 12/01/14 seniority list, the most junior Denver captain was hired 12/05/05. The most junior captain line holder in Denver as of the January bid was hired 03/24/03. There are a few vacation relief lines that went slightly junior to that, but I don't have the means to figure that out at this moment.

Hope this helps, but I wouldn't count on good news re: captain juniority in Denver for the foreseeable future. I wouldn't be a bit surprised, actually, to see some current junior Denver captains either forced out of the domicile or downgraded to FO's (this would be the pilot's option under our CBA).
