Frontier Airlines (F9, Denver International) is aiming to go public as early as the second quarter of this year people with knowledge of the matter have told Bloomberg news.

According to the report, JPMorgan Chase & Co., Deutsche Bank AG, Citigroup Inc. and Evercore Partners Inc. are the offering's leading underwriters. Barclays Plc, once poised to lead the IPO, will now have a more passive role after the departure of its airline analyst, the people said.

This will be Frontier's second listing as prior to its takeover by Republic Airlines (Indianapolis International) in 2009, the LCC was listed on the NASDAQ.

Arizona-based LCC investment specialists Indigo Partners LLC acquired the carrier from Republic in October 2013. At present, Frontier operates twenty-one A319-100s, twenty-six A320-200s, five A320neo, and sixteen A321-200s on flights connecting sixty destinations across the United States, Mexico, Cuba (to be discontinued in June), and the Dominican Republic.
