Our rating system is rated from one to seven stars on safety – with seven being the highest ranking. Within each airline, you will find the country of origin, airline code, booking URL, and seat map information.

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.
