Even though flying in an aeroplane is the safest mode of transport, recent disappearances and crashes have resurfaced the security concerns surrounding it. AirlineRatings.com publishes a list of the most dangerous airlines in the world every year based on a rating system of seven stars. They take into account multiple factors including fatalities and country blacklists. None of the airlines below attained more than two stars.
