An AA 777 captains' son goes to my school, and he is on my brother's hockey team. I asked him(the captain) and he said the pay varies, he gets paid more than lets say, an MD-80 captain for a few reasons including:
flight time(the individual flight)
those are only a few factors involved(i don't know all of them) but a high ranked pilot like a captain can easily earn 6 digits(as stated in above posts)
Give me a break, I created this username when I was a kid...
