A new report from WalletHub used available data to analyze the best and worst airlines in terms of overall service quality and functional performance. The analysis looked at the nine largest national airlines as well as two regional carriers (that report to the Department of Transportation because they have at least 1 percent of total domestic scheduled-service passenger revenues) in terms of 16 key metrics across four major categories. In the comfort category, the study assigned points to airlines in areas including leg room, entertainment options, Wi-Fi availability, the availability of complimentary refreshments, and price. (The data set included costs in relation to in-flight amenities for the sake of fairness in evaluating the value as a whole.) At the bottom of the list were the no-frills carriers Spirit and Frontier (which also ranked as the most affordable). Read on to find out which airline came out on top in the comfort category, and which others round out the list of most comfortable airlines.
