Pilots at financially strong companies or those hoping to build up a B fund as part of their net worth need to be aware of some major drawbacks of changing the current retirement age. As explained to me:

B-fund: Ask an over-60 F/E if he is getting any contributions towards his B fund. No he is not; the section 415(b) does not allow it. This is also the section that allows us to have a tax deferred fund to make up for the requirement for pilots to retire earlier that Social Security limits. Theoretically, we could lose this entire benefit because it could be argued that we do not qualify for it.

That should be enough to encourage the 45-55 year olds to write their congressman!
