United last on J.D. Power customer satisfaction survey, but the airline is improving

United Airlines remained the worst-ranked traditional airline when it comes to consumer satisfaction, according to a new J.D. Power survey. But the airline improved over last year’s score. Customers gave Alaska Airlines the highest rating among the 5 traditional carriers in the study for the twelfth straight year, with a score of 801 on a 1,000-point scale, followed by Delta Air Lines with 788, J.D. Power said Wednesday. American Airlines came in third, followed by Air Canada and United. United was also the lowest-ranked carrier last year, when it scored a 708. This year, United scored a 723, J.D. Power said. While LCCs JetBlue Airways and Southwest Airlines earned the highest ratings overall, improvements in satisfaction were driven by the traditional carriers, according to the survey. <br/>
