AirAdvisor, a Boston, Massachusetts-based claims-management company, published its first-ever top 10 US airlines rankings on July 20. The company analyzed data from January 2022 until May this year.
AirAdvisor evaluated airlines on a ten-point scale based on nine criteria: reliability, comfort, safety, price, customer reputation, airline lounges, professional reviews, family travel, and traveling with pets. The overall score is taken from the average of the individual criteria scores.
"The result: analyzing nearly 1 million reviews, over 5 million flights, and 25 different individual factors," AirAdvisor said in its press release.
At the top of the list: Delta Airlines, which had an average score of 7.67, was crowned the best US airline.
But two popular airlines — Frontier and Spirit — were ranked at the bottom of the list, with overall scores of 3.22 and 4.11, respectively.
Insider has included the scores of each airline in three criteria — safety, comfort, and reliability — as these are some of the most important factors for passengers when flying with airlines.
