I would much sooner be flown to my destination by a good pilot than an old pilot.
Firstly, seniority irrespective, anyone in either seat has to pass the appropriate courses etc. - and not all do
Would you rather your pilots use seniority, which in some ways equates to experience (but not all

) to govern who gets commands? Or by who takes the least fuel? Accepts the most defects? Exceeds the max duty hours by the largest amount? Who puts cost savings over safety? These might be the sort of criteria Management use to select their Captains in a non-Seniority structure
