Just my .02, worth exactly what you paid for it, but...
I don't think an 'insert small aircraft' pilot should be paid the same as an 'insert large aircraft' pilot, UNLESS they are working for the same company.
If I am #1 on a seniority list, why should I take a pay cut to fly any aircraft in the inventory? We are in a seniority based business, and although you can be carrying 50 or 300 people behind you, you aren't directly effecting the bottom line of the company. If I would rather fly one hour shuttle flights all day why should that change my paycheck as the #1 pilot?
