SEATTLE, May 14, 2014 /PRNewswire/ -- Alaska Airlines ranked highest in airline customer satisfaction among traditional carriers for the seventh consecutive year in the J.D. Power 2014 North America Airline Satisfaction Study SM. The organization also announced today that frequent fliers ranked Alaska Airlines' Mileage Plan highest in overall customer satisfaction in its first-ever Airline Loyalty/Rewards Program Satisfaction Report SM. "I could not be more proud of our employees for delivering the level of service that we believe helped us receive our seventh straight J.D. Power award and top honors for our Mileage Plan," Alaska Airlines CEO Brad Tildensaid. "We're very honored by this recognition from our customers and remain committed to being the easiest airline to fly." In the overall rankings among traditional carriers, Alaska received the highest score of 737, up 20 points from last year. For the first time in seven years, customers ranked Alaska highest in every category that J.D. Power evaluates, including reservations; costs and fees; check-in; boarding/deplaning/baggage; aircraft; and flight crew. J.D. Power 2014 North America Airline Satisfaction Study SM is based on responses from more than 11,300 customers who flew on a major North America carrier between March 2013 and March 2014. The study measures overall customer satisfaction based on performance in seven measures (in order of importance): cost and fees; flight crew; inflight services; aircraft; boarding/deplaning/baggage; check-in; and reservation. Traditional carriers are defined as airlines that operate multi-cabin aircraft and use multiple airport hubs. Alaska Airlines Mileage Plan Ranks Highest in Overall Customer SatisfactionJ.D. Power also announced Alaska Airlines' Mileage Plan ranked highest in overall customer satisfaction based on six factors, including ease of redeeming points/miles; reward program terms; account maintenance/management; ease of earning points/miles; variety of benefits available; and customer service. "A key strength for Alaska Airlines is its partners program, which allows its members to earn points when flying one of its partner airlines or staying at one of its partner hotels," according to J.D. Power. "While partner programs are not unique to Alaska Airlines, the carrier's vast partner networks allow its members to earn points through a number of airlines and hotels."
