Pilot salaries in airlines like AA are by far not the only spenditures on flight crew. Without going into details if AA and Ryanair pilots will be paid the same, it will still cost AA 50%+ more.
Another thing is that most of the pilots never had any other job (non-flying) which pays $200k+ a year which is not their fault for sure but it restricts their ability to judge about fairness of their remuneration. Most of the pilots can't imagine what a loads of cr@p people making $200k+ on the ground in most industries are taking on a daily baisis. 110 nights in hotel is not too much comparing to that, really.
