In recent years, Frontier, which likes to portray itself as Denver's hometown airline, has regularly gotten hammered in customer satisfaction reports.

Take its brutal finish in the 2014 Airline Quality Rating study.

Did the carrier do better in the Air Travel Consumer Report, issued by the U.S. Department of Transportation.

Below, see the photo-illustrated list pertaining to customer complaints, with the thirteen U.S. airlines in question ranked from best to worst. Included is DOT data from both 2014 to 2015. And while Frontier's performance last year wasn't exactly outstanding, its tumble this time around qualifies as absolutely spectacular.

Count them down here, and then check out the complete Air Travel Consumer Report, included in its entirety.
