The cost of labor is just a small piece of the puzzle that differentiates LCCs from traditional carriers. If Delta paid it's pilots the same as jetBlue, it would still have higher overall costs than the LCC....and frankly, LCCs are here to stay...they are the product and service innovators that will continue to create and exploit new growth segments in the industry. Now if jetBlue paid its pilots the same wages as Delta, paid into its non-existent defined-benefit retirement plan at the same funding levels, and paid its bankers the same for its airplanes as Delta, then it might be in big troube - so the concept works in the opposite direction.
