Alaska Airlines and JetBlue Airways still rank highest in the annual J.D. Power survey of passengers on the nine largest North American airlines, and the firm says overall traveler satisfaction with the industry is at a 10-year high.

J.D. Power said Wednesday that Alaska Airlines ranked highest among traditional airlines for the ninth straight year and JetBlue was the top-rated low-cost carrier for the 11th year in a row.

The researchers say passengers are growing more tolerant of paying extra fees. Widespread fees on checked bags began in 2008 but are now common.

J.D. Power says its online survey covered more than 10,000 people who flew on a major North American airline between April 2015 and March 2016.
