Alaska Airlines is on top when it comes to customer happiness. The carrier was just named the best in customer satisfaction by the American Customer Satisfaction Index Travel Report for 2018-2019. This report gives us a glimpse into how domestic travelers perceive their experiences with airlines in the United States.

Alaska managed to pull in a score of 80 out of 100 for the latest ranking. Southwest previously held the top spot. However, the popular budget carrier's score fell down to 79 this time around and created the perfect conditions for Alaska to soar. Southwest actually tied with JetBlue for second place. Delta and American Airlines followed close behind. Northwest Airlines and Continental ranked at the bottom.

All airlines had a combined average score of 74 out of 100 in this year's survey. That represents an increase of 1.4 percent from last year's score. A score of 74 may not seem all that stellar. However, it is actually very impressive for an industry that is more or less designed to elicit gripes from customers.

One piece of news that may surprise some travelers is that satisfaction among airline customers is up all around. It turns out that customers are about as happy as they've ever been when it comes to what the flight experience has to offer. Some of the factors that have been helping to boost customer satisfaction all around include mobile apps, mobile check-in options, smoother boarding experiences and cabin cleanliness. The one category where passengers still aren't happy is seat comfort. That's no doubt due to shrinking seat sizes on planes across all carrier networks in the country.
