Frontier Airlines files for IPO

David Zalubowski

Low-cost airline Frontier today filed for an initial public offering, which means it likely plans to go public sometime in May. The Denver-based company last year flew 14.9 million passengers through 59 airports in the U.S., Mexico and the Caribbean.

Top line: The Denver-based carrier's income statement reflects its budget sensibilities, with $200 million in net income on $1.7 billion in revenue. This is up from $146 million of earnings on $1.37 billion in revenue in 2015.
