The Airline Quality Rating (AQR) was developed and first announced in early 1991 as an objective method for assessing airline quality on combined multiple performance criteria. This current reporting, the Airline Quality Rating 2023, reflects monthly Airline Quality Rating scores for calendar year 2022. AQR scores for 2022 are based on 15 elements in four major areas that focus on airline performance aspects important to air travel consumers over the calendar year of 2022. The Airline Quality Rating 2023 is a summary of data for U.S. airlines that are required to report performance by virtue of having at least 0.05% of domestic scheduled-service passenger revenue during 2022. Using the Airline Quality Rating system of weighted averages and performance data in the areas of on-time arrivals, involuntary denied boardings, mishandled baggage, and a combination of 12 customer complaint categories, the AQR reports airlines' comparative performance for the calendar year of 2022. This report contains a summary of the AQR methodology and data that tracks comparative performance quality for domestic airline operations for the 12-month period of 2022 and the industry. Also, comparative Airline Quality Rating data for 2021 are included, where available, to provide historical perspective regarding performance quality in the industry.
