My parents traveled by air (as well as by ship) numerous times a year for half a century. My father had "the travel bug" to the extreme (having grown up poor in a small rural area), and was a surgeon so he could afford it.
One of my first memories was a trip by air to Jamaica (or was it Cuba? or both) in 1949 when I was just a year old. I remember traveling across the Atlantic in the early 1950's, when airplanes had pullmans. We were quite the vagabonds. We went to every continent except Antarctica and spent as much time away as at home.
My father died at 70 from cancer. My mother is still alive and will be 98 in a month. My conclusions are that air travel had absolutely no impact on life span, and (in my father's case) that money and knowledge cannot protect you from everything.
