Dumbdumb, You neglect to mention that pilots without a FE line number moved to the bottom of the FE seniority list if they decided to make the move to FE when they reached 60 (soon to be 65) This protected the seniority of the PFEs that joined Atlas with no intention of becoming pilots. Can you imagine how many pilots would have made the move to the FE seat if they could have retained their seniority when they reached 60? Maybe even you were one of the PFEs that benefited from this rule?
