I never liked comparing air travel to car travel. It's just not a fair comparison.

Per mile danger is the most favorable towards airlines, but you could use per-journey and then airline travel is 3-4x more dangerous than cars.

The best you can do is either say "airline travel is plenty safe enough" or make direct comparisons like "traveling from NYC to LA via airline is safer than driving the same distance".

This wouldn't be a fair comparison either, unless you normalized for number of people on the journey. (As done in passenger-miles.)

My point was that the 3-4x stat is also not fair. My point was that there are very few fair comparisons, and gave some examples that I think are fair statements.
