Frontier Airlines (F9, Denver International) has held preliminary discussions with investment banks over a possible IPO. Sources who spoke to Bloomberg news on condition of anonymity said the carrier is considering starting a formal IPO process as early as next year but that no firm decision has yet been taken.

The carrier is no stranger to the stock market having traded publicly on the NASDAQ up until 2008 when it was taken private following a Chapter 11 bankruptcy filing. In 2009, it was acquired by Republic Airlines (Indianapolis International) parent, Republic Airways Holdings, before being sold off to private equity firm Indigo Partners for USD145 million in 2013.

Under Indigo's ownership, Frontier has been repositioned as an Ultra Low Cost Carrier (ULCC) operating an all-Airbus (AIB, Toulouse Blagnac) fleet of thirty-three A319-100s, twenty-three A320-200s, and three A321-200 (SL)s on scheduled flights throughout the United States as well as to the Dominican Republic, Mexico, and Jamaica.
