Air France, British Airways, KLM and Lufthansa are the safest airlines in Europe, according to the Geneva-based air Transport Rating Agency (ATRA), which this week published a list of the world's 10 most reliable carriers.
The safest US carriers are American Airlines and its associate American Eagle, together with Continental Airlines, Delta Airlines, Southwest Airlines, United Airlines and US Airways.
Japan Airlines was the only airline outside the US and Europe to make it into the top 10, although the rating agency did not place the airlines in any order.
ATRA said it used available information on 15 criteria, such as the average age of the aircraft used or the homogeneity of the fleet.
The agency explained that to understand airline safety, one needed not only to look at accident figures, but also "technical, human, organisational and external" elements.
