I tried to make this point in an earlier post, but amid all the euphoria, it seems to have gone through to the keeper:
Improving your own salary and conditions will put other pilots out of a job.
This is a basic economic reality. Improvements to YOUR terms and conditions are at the expense of other pilot's jobs. This is because the money that pays the increased salaries must come from the public.
But the public, generally speaking, can't afford the extra cost, or are not prepared to pay it.
And no, it is not just another 20 or 30 cents on the airfare.
