Here's something for you all to think about:
Any increase to pilot's T&Cs will put other pilots out of a job.
The travelling public can only afford to pay so much. To double pilot salaries, for example, would require the public to pay roughly twice what they presently pay in airfares.
Doubling pilot salaries would (roughly) reduce pilot numbers by half.
The above is a very rough guide as to the effect of increased pilot remuneration and conforms with general economic theory. Please don't rattle off one of those calculations that show how a tiny, $0.20 cent increase in ticket prices can finance huge pay increases for pilots. Those calculations are rubbish.
