Hawaiian Airlines was No. 1 for the second consecutive year in a quality ratings study that looks at air carrier performance last year in terms of on-time performance, baggage handling, denied boardings and customer complaints.

Hawaiian beat out 17 other carriers evaluated in the 20th annual Airline Quality Rating study conducted by researchers at Purdue University and Wichita State University.

Hawaiian was also the top-ranked airline in the annual AQR study for 2006 and 2008, and was not included in the report for 2007.

Hawaiian was best of all airlines in on-time performance, and was second-best in denied boardings and mishandled baggage.
