Not to mention, if management really wants/needs RJ lift in whatever capacity, DL, UAL, SWA, etc pilot groups can fly unlimited amounts with no restrictions. As to the myths about how its not profitable at a mainline, the numerous billions spent on management mistakes (too numerous to list in a short post) directly related to outsourced ACMI RJ lift, including bleeding the coffers with yield trashing spawns like IndyAir, Republic Air Group and soon SkyWest, among many others, proves that insourcing may be the only long term way to operate them profitably in the first place.
