Can anyone point out the difference between a so called "no frills" airline like SW or Jetblue vs an American or Delta etc? There may have been a difference at on point a long time ago when SW first came out, but it seems like the differences now are only in how they advertise themselves to the public. For example the only differences between them is whether you get an assigned seats or get pretzels. As far as pricing I have seen that you can get gouged just as easily by a "low cost" ailine as by a major carrier.
