Let me clarify my statement on PEOPLExpress...

Spirit is different from PEOPLExpress in a lot of ways. However, one of the things that eventually did them in was ignoring threats from their competition. They never factored into their business model that major, full service carriers would meet or beat their own low no frills fares, and then add capacity to dilute demand. They were highly criticized for their poor customer service and lost market share as a result, among other things that did them in. That's exactly what could happen in Ft. Lauderdale.

Let's hope that NK's customer service doesn't become its "Waterloo." Either our guys in Phoenix are incredibly bright and KNOW this ULCC model will work, or they haven't anticipated the entry into our markets by Jet Blue, Virgin America, and others and will have to find a way to defend NK's turf.
