While some of the pilots are now more nervous about retirement funds in light of UAL et al, the truth is that our A fund is currently well funded with no issues in sight. The company has never lost money, although they have not always made as much as they wanted -- there is NO time in the history of any of the pax carriers you could say that, even during regulation.
Our A-fund is essentially 50% of our final average earnings during the highest 5 years of the last 15. There are several creative ways of artificially making that number work out to well over 50% of a typical year's pay.
We have a company funded B-fund that is 6%. Overally, it is not a bad balance, as historically, B funds haven't done all that well, too dependent on external factors and personal choices, while A funds with solvent companies are pretty reliable.
On the travel benefits, yes, good interline rates for discounted travel, standard stuff, reduced airfare, hotels, rental cars, etc.
