Given how much more moolah Southwest has compared to Republic, chances are more than good that the former will best the latter on Thursday, when a formal auction for Frontier is slated to take place. That's grim news for locals with pride in their hometown airline (which will almost certainly disappear if Southwest comes out on top), not to mention Frontier employees like those who rallied at Mayor John Hickenlooper's office last week, many of whom are sure to lose their livelihoods due to consolidation. As a result, this week could lead directly to the final Frontier.
