Unless the US market is a whole lot different than the European market, I doubt that!
Their model is based on that of highly successful European LCC's like Ryan Air and EasyJet. EasyJet has had a higher market capitalizatin than their home country's flag carrier, British Airways, for some time, and Irish-based Ryan Air earlier this year launched an almost succesful takeover bid for Ireland's flag carrier. Their model has made these LCC's consistently profitable even when the legacy airlines or flag carriers were bleeding red ink.
The model is also being repeated on the Continent with LCC's like Air Berlin and Germanwings, also highly profitable. Air Berlin just placed the largest order to date from a European airline (20 planes) for Boeing's new super efficient long range 787 Dreamliner.
