Personally, I do not. As with my investment portfolio, I am comfortable with a considerable amount of risk. Unless Delta were to offer us some ridiculous amount of pay in return for what is essentially an unlimited profit sharing plan, e.g., something akin to 12-14% APR on a CD, I believe that we are better off accepting the risk of no profit some day in return for higher returns in profitable years.

But that's just me. Others may be more risk averse and prefer the certainty of a higher fixed pay rate. The trick, though, is to ensure that you're not mistaking the pay that you've bought with your profit sharing for an actual increase in compensation.
