No Im not talking about the stock purchase program, which is a 15% discount of the lower of the stock price on the first and mid year prices. (not sure the exact dates, I think end of Dec, and June).
This is kind of shady if you ask me, they paycheck deduct your predetermined amount and you can only access that money twice a year, purchasing stock. During that time skyw invests the money they are not paying you and makes the interest that you should be making. (just like uncle sammy does with income tax). Many companies allow you to purchase stock at a discount any time during the year, giving you full leverage of your hard earned money. Skyw management is smart, they play off our ignorance to make a little extra cash.

Skyw used to issue stock options (option to buy stock at a predetermined price on a specific date). I.e. you would get the option to buy say 100 shares at 19 dollars per share on a given date. So you sell the options for the difference of the current price vs. grant price and take the profit. (26.5-19=7.5 7.5*100=750$)
That is a thing of the past. You now get a set amount of shares that become yours on a given date, with the restriction that you are still employed with skyw. Point is, the new program dosent amount to much. Last person I talked to got something like 13 shares that become theirs if they are still employed at skywest in 2 or 3 years. This is suppose to reduce turnover.
Again this is off the top of my head, Im to lazy to look up the exact specifics.

Don’t get me wrong, this is a good thing, but many companies with "god sent" management are much more generous. I know jetblue gets options as soon as they finish training. Not sure about swa's options program, but I here it’s a huge part of the overall compensation.
