You would do yourself a big favor and research how our current A fund is funded by the company. How much money is in it. Who are the other employees that participate in it. Also research the current pension laws and what is required by the company by law. Even if the pilots voted to eliminate it you would be locked in at what you have earned as far as high five and YOS.
It is a lot of money, invest the time and do the research. You will earn a lot of money here. Hardest part is keeping it and investing wisely.
