Frontier Airlines will expand its presence at the Austin airport, adding four new nonstop flights beginning in March. Why it matters: The low-cost carrier's decision to add more routes comes as Spirit Airlines files for Chapter 11 bankruptcy protection.

Frontier Airlines is expanding its operations at Austin-Bergstrom International Airport with the addition of four new nonstop routes. The Denver-based discount airline announced Nov. 19 that it is adding routes from Austin to Chicago, Orlando, Cincinnati and Phoenix.
