US-based airlines have just completed the country’s safest ever decade for air travel.

According to a recent study conducted by the Associated Press, 153 people died in commercial aviation accidents over the last ten years, which amounts to two lives for every 100 million passengers flown.

The figure marks a substantial improvement over years prior. Only ten years before, which was then the safest period yet for commercial air travel in America, passengers’ chances of dying in a commercial airline crash was 10 times the risk it was from 2002 to 2011. At the start of commercial jet travel, the risk was even greater; 1,696 people died in airline accidents from 1962 to 1971, amounting to 133 lives for every 100 million passengers.

Airsafe.com Foundation director and former Boeing safety engineer Todd Curtis said that although commercial air crashes weren’t yet a thing of the past they are quite simply much more rare than they were just a couple of decades ago.

All of the fatal commercial air crashes in the US over the last 10 years have been on regional airlines, which are usually operated by smaller firms that fly under major brand names such as Delta Connection, American Eagle and United Express. The last fatal crash with a larger aircraft was AA Flight 587, in which 265 people were killed shortly after departure from JFK airport in New York in November, 2008.
