I don't think so. If there's money to be made they want it. Too many airlines serving too many of the same routes. They just need a merger or two to take care of that then they can dominate. If they merged they could fill more seats and with full seats they'd realize the 737's were more efficient than the RJ's pulling in more per mile. Of course pilots would be losing their jobs, but the legacy guys will hang around. Thats IMHO
