Who would it hurt? Sure any one flying the 777 will still get a premium international override pay. Think outside the box seniority based pay is a total win. But if you only think that the economy will stay roaring or no disaster ever hits or they never swap out your 7er's for 737's then maybe it's a wash. but, for the rough times and downfalls or you just don't want to live or commute to precious Atlanta to get a raise then seniority based pay is a win win because your pay will never go down just up...
