Projecting wages and the size of seniority lists over 2 or 3 decades as if things were static is pointless. This industry is the antonym of stability.
What if you were considering America West in the early 80's. Or Southwest in the 70's? Granted I don't know what they payed at the time, but I'm sure some lippy Delta pilot would have chimed in about how much more THEY make.
