The scores are based on 15 components in the four key areas that air travel consumers find important, including on-time arrival, mishandled baggage, involuntary denied boardings and complaints filed with the Department of Transportation. The data is sourced from the Air Travel Consumer Reports from the Department of Transportation.The authors of the report are Dr. Brent Bowen and Dr. Dean Headley. Dr. Bowen is the head of the Department of Aviation Technology at Purdue University. Dr. Headley is an associate professor of Marketing at the W.
