The rating system takes into account a number of different factors related to audits from aviation’s governing bodies, lead associations, as well as the airlines, own safety data. Every airline has a safety rating breakdown so you can see exactly how they rate. Over 230 of the airlines on the site that carry 99 percent of the world’s passengers have a product rating. Given that low cost, regional and full-service carriers are so different we have constructed a different rating system for each which can be found within each airline.
