We can compare against another mode of human-controlled transportation. There are 1.37 deaths per 100 million passenger-miles driving in the US [1]. In comparison, there are ~0.2 deaths per 10 billion passenger-miles flying. Converting into the same units, there are 137 deaths per 10 billion passenger-miles driving. So you are 685X more likely to die while driving/riding in a car than flying. That's almost three orders of magnitude worse! Humans are pretty terrible drivers in comparison to how good we are at flying.
