Frontier Airlines is in comeback mode, at least financially.

The Denver-based airline is seeking an initial public offering to attract investors. The low-cost carrier that features photos of animals on the tails of its planes reported a net income of $200 million in 2016, up nearly 43 percent from 2014.

But while the company's profits are soaring, its customer service ranking is the second-worst among U.S. airlines.
