A good friend of mine is a 777 captain for United. He tells me frequently that my job is harder than his. But he earns more. He has also 'paid his dues'. I am 'paying' them now. At least I hope so.
The idea that the larger aircraft flies a harder schedule is absurd. Not to dis their work at all. But we also work all hours and make up to 6 approaches per day, etc.
To say one is better or harder is just not right.
