Ok here we go, The 737 type is a requirement for several reasons. The first reason was to help a low cash if no cash start up company that was struggling to compete against AA out of dallas. From a business insurance stand point, the type allows the company to keep insurance cost down. Plus the initial training is informational , but if you don't have that type you will be lost, being lost and not knowing cost the company money. The type does help the company keep cost down. I am very proud of the type I bought. I paid it off after being at SWA for a year and a half, what a great investment for me and SWA.
