This way of thinking is too surface. Think deeper. Running jets inefficiently (2 50 seat gass-guzzlers for one 100 and up seater) is Terrible in a long run--It will end up in the company losing money and further layoffs. Also, deciding to fly a 50-seater for life is not an option since regional jobs change on a daily basis (contracts ending, selloffs, closed domiciles constantly, etc.). No regional will be there for life. So, you leave the regional and go to the major where you will "cheerlead" the end of the 50-seater all the way to the bank!
