Turns out, though, that another carrier -- Spirit Airlines, which wasn't included in the AQR report -- has generated more gripes than Frontier according to "The Unfriendly Skies," a new report from the U.S. PIRG Education Fund. But Frontier is gaining ground at an unflattering clip. See details, graphics and the complete report below.
Spirit is certainly a familiar airline to Denver travelers, and in January, it hyped travel to the city by alluding to the legalization of marijuana. A promotion touted "fares so low they're barely legal in some states."

The complete report is below, but here's the damning summary of Spirit's performance:
Spirit Airlines, which markets itself as a low-cost, no-frills airline, generated the most complaints per 100,000 passengers every single year in the study, by a large margin. It was nearly three times as likely to generate complaints as the second place airline each year. As the airline has grown in the past every years, complaints against the airline have skyrocketed.
Since 2008, the DOT has hit Spirit with five different fines totaling $565,000 for violating various consumer protection laws concerning over-sales, baggage, and multiple cases of deceptive advertising.
In fact, Spirit's ranking on complaints is so out of proportion to the others that a second graphic actually excludes it. In the latter, you can see that Frontier, represented by the orange line, was in range of the other airlines until 2012, at which point complaints spiked, pushing the carrier above all its competitors other than Spirit:
How does the study illustrate Frontier's fall from grace?
Continue to read more about airlines and customer complaints, including additional graphics and the complete study. Another pair of graphics tell the tale. In this one, representing 2012, Frontier places seventh in terms of customer complaints....
...but by 2013, it had shot up to second:
The Frontier blurb reads like so:
Frontier Airlines has grown considerably in the last several years, and its complaint volume has grown as well. Frontier saw a large jump in 2013, becoming the most complained-about airline in the group besides Spirit Airlines.
