Since the most junior captain position should pay more than the most senior fo position. And all the small twin jets......md-80 thru 90 series, dc-9 all series, 737 all series and airbus 318-321(dont know if that is all the airbus series) should pay the same. The 757 and like powered should pay the same. 767 and a-330 should pay the same and 777 and 747 should pay the same and then if there ever is a 787 it would fit in there somewhere.....all out mock rebid where the senior guys go to the high pay airplanes and so on all the way down to the lowest pay and least senior....then ratio that list.....do a five year fence and call it good........nah that is too easy
