It's the latest airline ranking this year among a series released by different organizations.
The J.D. Power North American Airline Satisfaction study's scores and rankings are based on cost and fees, in-flight services, aircraft, boarding/deplaning/baggage, flight crew, check-in and reservation, according to responses from 5,966 passengers who flew between March 2018 and March 2019.
Overall, customer satisfaction with airlines is at a record high based on the J.D. Power scores, due to newer planes, better ticket value and improved technology for reservations and check-in.
“Fleets are newer and travelers generally feel that they are getting great value for their money,” said J.D. Power travel intelligence lead Michael Taylor in a written statement.
However, in the airline industry overall, in-flight services continue to be the lowest-ranked factor in the study, according to Taylor. That includes connectivity, in-seat power, food service and entertainment.
