Dan,
Sorry this isn't as in depth as I would have liked to explain. Brightscope is a third party and not affiliated with SWA, or any other corporations as far as I know.
Anyway, our high score is a BS ranking based on participant rate, company match, fees, fund options, .... The match percentages are well known, most pilots if not all hit the 402(g) federal limits ($17k in 2012).
Someone mentioned our Top Hat program. To further describe this plan: Our Top Hat program is a Rabbi Trust non-qualified compensation plan. Essentially, it allows us to set aside up to $50k per year (tax deferred), lowering our current taxable income. This money is not protected from unsecured creditors though, and can be taken back if SWA were to ever go through bankruptcy. The options are limited in this plan; I think the income limit is $135k to participate. You have two options upon departure (lump sum or paid evenly over 5 years). There are other details I'm not familiar with, as I don't participate in this program. Honestly, not positive if BS even considers the TH program.
Someone mentioned "high compensated" employees. This is a federal non-discrimination test. Prolly be Googled, but in essence, the feds limit high compensation employees (by definition, almost all SWA pilots; think it was $110k last year) to a maximum 401k deferral relative to the savings rate of the "non-high" compensation rate employees. For example, if the rampers on average save 4% of their income into the 401k, this limits pilots to 6% (I Googled it

. We'd miss out on 3.3% match. Hope that is not confusing.
deleted, I started to get in the weeds a little too much Already getting too long, let me just try to summarize.
By contract, SWA caps all retirement plan matches to $25k annually.
Any amount over the 415(c) excess limit is cut as a check up to this $25k limit.
Our 401k provides access to a brokerage account. The PCRA (Personal Choice Retirement Account - Schwab), we can direct up to 95% of our 401k. From here, aside from the funds that are already in the Mutual Fund side of the account (& LUV), you can buy pretty much anything (well aside from high risk stuff - I think; again I don't this so not as familiar).
The fees are incredibly small. The S&P 500 index fund has a 0.025% expense ratio.
Schwab ETFs trade fee of charge, and ARE the lowest in the industry for the particular asset class.
We self manage the 401k options. Someone mentioned an annuity option coming up. I know John, he is hyper cost sensitive, so the annuity will probably be one of the best in the nation as well.
